The Reality: Available at Some Pharmacies, Illegal to Buy Without a Prescription

Walk into the right pharmacy in Kuta, Seminyak, or Legian, ask confidently for "diazepam 5mg" or even "Valium," and there is a reasonable chance a box will appear from behind the counter without anyone asking you for a prescription. This has been the case for years. Backpacker forums reference it. Long-term expats know which pharmacies are more relaxed. Some tourists treat it as a feature of Bali — a place where you can manage your anxiety or sleep problems without the administrative overhead of seeing a doctor.

This article is not going to pretend that the over-the-counter benzodiazepine market in Bali does not exist. It does. But what most tourists fundamentally misunderstand is the legal status of what they are participating in when they buy Xanax or Valium without a prescription in Bali. This is not a local custom that differs from Western norms. It is not a grey area in Indonesian pharmaceutical regulation. It is not the equivalent of buying ibuprofen without a prescription in a country where it is sold behind the counter. Purchasing benzodiazepines without a prescription in Indonesia is a criminal offence — and it is one where the pharmacy's willingness to sell is not a legal defence, a mitigating factor, or even useful context if you are caught.

The casual availability at some pharmacies reflects the pharmacy breaking Indonesian law, not Indonesian law permitting the transaction. Understanding that distinction is essential before you make any decisions about benzodiazepines during your Bali trip.

Indonesian Drug Law: Where Benzodiazepines Actually Sit

Indonesia regulates controlled substances through two primary legislative frameworks that operate in parallel. Tourists often hear about Law No. 35/2009 on Narcotics (Undang-Undang Nomor 35 Tahun 2009 tentang Narkotika) because it governs the substances with the most dramatic penalties — heroin, cocaine, methamphetamine, MDMA, cannabis — and because the death penalty provisions under that law generate international news. For a full breakdown of what that law entails and the sentences it carries, see our guide to Bali's drug sentences including the death penalty.

Benzodiazepines, however, are primarily regulated under a different and older piece of legislation: Law No. 5/1997 on Psychotropics (Undang-Undang Nomor 5 Tahun 1997 tentang Psikotropika). This law classifies psychotropic substances into four groups (Golongan I through Golongan IV), with Group I being the most restricted and Group IV being the least restricted — though "least restricted" under Indonesian law still means these are controlled substances requiring a valid prescription for lawful possession.

Benzodiazepines sit in Group IV (Golongan IV) under UU 5/1997. This classification means they have accepted medical uses in Indonesia and are available through the legitimate pharmaceutical system — but only through the legitimate pharmaceutical system, meaning with a valid prescription from a licensed Indonesian doctor or equivalent documentation when imported from abroad.

The oversight body for pharmaceutical regulation in Indonesia is Badan Pengawas Obat dan Makanan (BPOM) — the National Agency of Drug and Food Control. BPOM maintains the official list of scheduled psychotropic substances, regulates their import, and governs what documentation is required for legitimate possession. Their regulations are binding on pharmacies and on anyone bringing controlled psychotropics into Indonesian territory.

It is worth being clear about how UU 5/1997 and UU 35/2009 relate. They are separate laws with separate penalty scales and separate classification systems. The psychotropics law is not the narcotics law. Benzodiazepines are not classified as narcotics under the 2009 law. This matters because the penalty exposure under UU 5/1997 — while serious — is not the same as the catastrophic penalty exposure under UU 35/2009. But "less severe than a potential death sentence" does not mean "not serious." Up to five years imprisonment is not a trivial outcome for a tourist who bought a box of diazepam without a prescription.

Benzodiazepine Classification Under Indonesian Law

Generic Name	Brand Name(s)	Indonesian Classification	Governing Law	Available in Indonesia by Prescription?
Alprazolam	Xanax, Alganax	Golongan IV Psikotropika	UU No. 5/1997	Yes — prescription required
Diazepam	Valium, Stesolid, Valisanbe	Golongan IV Psikotropika	UU No. 5/1997	Yes — prescription required
Lorazepam	Ativan, Merlopam	Golongan IV Psikotropika	UU No. 5/1997	Yes — prescription required
Clonazepam	Klonopin, Riklona	Golongan IV Psikotropika	UU No. 5/1997	Yes — prescription required
Nitrazepam	Mogadon, Dumolid	Golongan IV Psikotropika	UU No. 5/1997	Yes — prescription required
Clobazam	Frisium	Golongan IV Psikotropika	UU No. 5/1997	Yes — prescription required
Zolpidem	Ambien, Stilnox	Golongan IV Psikotropika	UU No. 5/1997	Yes — prescription required
Midazolam	Dormicum	Golongan IV Psikotropika	UU No. 5/1997	Yes — hospital/clinical use only

Note: Zolpidem (Ambien/Stilnox) is classified as a Group IV Psychotropic in Indonesia despite being technically a Z-drug rather than a benzodiazepine. Its regulatory treatment is identical. Midazolam is primarily used in clinical anaesthesia settings and is not available through retail pharmacies under any circumstances.

What the Penalties Look Like for Tourists

The penalty provisions of UU 5/1997 that are most relevant to tourists break down along a few distinct scenarios:

Possession Without a Valid Prescription

Article 62 of Law No. 5/1997 is the core provision applying to individual possession. It provides that anyone who without right possesses or carries psychotropic substances shall be sentenced to a maximum of 5 years imprisonment and a maximum fine of IDR 100 million (approximately USD 6,200 at current exchange rates). This applies to possession of Group IV psychotropics including all benzodiazepines.

"Without right" in practice means: without a valid prescription from a licensed Indonesian doctor, or without the documentation required for lawful import if the substance was brought from abroad. The quantity possessed affects how severely the charge is prosecuted but not whether the offence exists. One strip of alprazolam tablets purchased without a prescription is technically as illegal as a full month's supply.

Bringing Benzos from Abroad Without Declaration

If you bring benzodiazepines from home and do not declare them at customs, you face two separate legal exposures simultaneously:

1. A customs violation under Law No. 17/2006 on Customs (Undang-Undang Kepabeanan), which prohibits the undeclared importation of controlled substances, and
2. A psychotropics possession offence under Article 62 of UU 5/1997, because undeclared importation means you do not have lawful import documentation and therefore do not have lawful possession.

These are not alternative charges — prosecutors can and do pursue both simultaneously. For the full picture of what Indonesian customs procedures look like when things go wrong, see our complete guide to Bali customs rules for tourists.

Purchasing From a Pharmacy Without a Prescription

This is the scenario that catches people off guard. You walk into a pharmacy, buy diazepam, and walk out with a box of tablets with a pharmacy label on it. In your mental model, having a labelled product from a pharmacy makes the possession legitimate. In Indonesian law, it does not. The pharmacy label is evidence of where you bought the substance. It is not evidence that you had a prescription or that your possession is lawful. The pharmacist who sold it to you may face criminal or regulatory consequences for the sale — but that is an entirely separate matter and has no bearing on your personal legal exposure.

This is not theoretical. There have been cases in Bali where tourists were arrested for possession of prescription medications purchased from pharmacies, and the defence that "the pharmacist sold it to me" was not successful. Indonesian law places the responsibility for lawful possession on the possessor, not on the person who made the sale.

Real Cases Involving Tourists

Comprehensive public records on benzodiazepine-specific tourist arrests in Bali are not always well-documented in English-language media, partly because these cases tend to involve lesser charges than narcotics cases and receive less international attention. However, several documented patterns are worth knowing:

Tourists carrying loose tablets — benzos removed from their original packaging and placed in pill organisers or small bags — have been detained at Ngurah Rai airport during both arrival and departure screening. In cases where the tourist could not produce a prescription, the tablets were confiscated and the tourist was detained for questioning. Outcomes have ranged from confiscation with a warning (rare, and dependent on the specific officer and circumstance) to formal charging. The risk is highest in the departure context, which is discussed in detail below.

More commonly, benzo possession becomes apparent during police encounters for unrelated reasons — a scooter accident, a noise complaint, a brawl at a bar. If police find unlabelled or unprescribed medications during a search, the possession charge compounds whatever the original situation involved. See our guide to getting arrested in Bali for how Indonesian police and prosecution procedures work in practice.

The Pharmacy Reality: What Actually Happens at the Counter

Bali has hundreds of pharmacies — apotek — ranging from the major national chains like Guardian, K24, and Kimia Farma to small independent neighbourhood shops. The regulatory compliance environment varies significantly between these establishments.

The major chains — Guardian, K24, and Kimia Farma in particular — generally comply with prescription requirements for controlled psychotropics. A pharmacist at a K24 in Denpasar is unlikely to sell you alprazolam or diazepam without a valid Indonesian prescription. They have too much regulatory exposure to risk a controlled substance sale, and their staff are typically trained on the legal requirements.

Smaller independent pharmacies — particularly those in tourist-heavy areas like the Kuta strip, Legian, and parts of Seminyak — operate differently in practice. Some do sell diazepam or lorazepam with minimal or no questions asked. The products they sell are legitimate pharmaceutical-grade medications with proper BPOM registration — the substances themselves are not counterfeit. The transaction is simply illegal because no prescription was involved.

From a tourist's perspective, the key points are:

• The fact that a pharmacy sold you the medication without a prescription does not make your possession legal. The pharmacy took a risk with its licence. You took a risk with your freedom.
• The friendly transaction at the counter does not create any paper trail that protects you. There is no receipt that says "sold with pharmacist's professional endorsement in lieu of prescription." You have a box of tablets and no documentation explaining why your possession is lawful.
• The pharmacist's professional licence and the pharmacy's operating permit are separate from your personal legal situation. Even if the pharmacy faced consequences for the illegal sale, those consequences would not reduce or eliminate your own legal exposure.

If you are already in Bali and have purchased benzodiazepines from a pharmacy without a prescription, the safest course is to see a local doctor, get a proper Indonesian prescription retroactively if the doctor agrees that it is medically warranted, and carry that documentation going forward. This is not a guarantee, but it is significantly better than carrying the substance with no documentation at all.

Bringing Your Own Benzos to Bali Legally

If you take benzodiazepines regularly — for anxiety, panic disorder, sleep, or any other condition — and you want to bring your medication to Bali lawfully, the process is straightforward but requires preparation before you travel. Do not leave this to the last minute.

Step 1: Original Packaging, Intact

Your medication must travel in its original commercially labelled packaging. The pharmacy label showing your name, the medication name and dosage, the prescribing doctor's name, and the pharmacy's details must be intact and legible. Do not consolidate medications into pill organisers, zip-lock bags, or any container other than the original pharmacy packaging. Tablets removed from their original labelling are anonymous — customs officers cannot determine what they are or whether they are lawfully held without laboratory testing, and that is not a process you want to trigger at the arrivals hall.

Step 2: Doctor's Letter

You need a letter from your prescribing physician, prepared before you travel, that covers:

• Your full name and date of birth as they appear in your passport
• Your diagnosis or condition being treated
• The medication name (generic and brand), dosage, and frequency
• The total quantity being carried and the number of days' supply this represents
• A statement that the medication is medically necessary and that interrupting treatment poses a health risk
• The doctor's name, licence number, clinic address, and signature

A standard prescription printout is not sufficient on its own. The letter should be on clinic letterhead and should be written with the understanding that it will be presented to Indonesian customs officials who may not read English with full fluency.

Step 3: Bahasa Indonesia Translation

Having your prescription and doctor's letter translated into Bahasa Indonesia by a certified translator (penerjemah tersumpah) significantly strengthens your position at customs. It demonstrates preparation and good faith, and it makes the documentation immediately legible to the Indonesian customs officers reviewing it. Your country's Indonesian embassy or consulate can provide a list of certified translators.

Step 4: Declare at Customs

On your arrival customs declaration form, declare your controlled medications. Select the red channel (declarations channel) rather than the green channel. Present your documentation proactively when you reach the customs officer. This is the single most important step. Failing to declare and then being found with controlled psychotropics converts a documentation review into a criminal matter.

Step 5: Quantity Limits

The general guidance from BPOM for personal import of controlled medications is a maximum of 30 days' supply for personal use without requiring a formal import permit. If you are staying in Bali for longer than 30 days and require a larger quantity, contact BPOM directly before travel to determine whether a formal import authorisation is required. For standard holiday trips of one to three weeks, a 30-day supply with proper documentation should be manageable at customs.

Carry Documentation Throughout Your Stay

Customs clearance on arrival is not the end of the documentation requirement. If you are stopped by police at any point during your stay in Bali and are found carrying benzodiazepines — whether in your bag, your hotel room, or anywhere else — you need to be able to produce your prescription documentation on the spot. Keep a copy accessible at all times. Keep the original packaging intact throughout your stay. Prescribed ADHD medications have the same documentation requirements; for a parallel discussion, see our guide to travelling with prescription ADHD medication to Bali.

What Happens at Customs When They Find Benzos

Ngurah Rai International Airport's customs operation uses a combination of X-ray screening, narcotics detection dogs, and targeted physical inspection. The narcotics dogs at DPS are trained primarily for the substances most commonly smuggled — cannabis, heroin, cocaine, methamphetamine — rather than for pharmaceuticals specifically. However, physical inspection triggered by X-ray irregularities, passenger profiling, or random selection can and does result in medication being identified.

The detection scenario that most commonly applies to benzodiazepines is not a dog alert but a physical search: a customs officer opens your bag, finds tablets in an unlabelled container or a medication that looks unfamiliar, and asks what it is. At that point, your response and your documentation determine everything.

If You Have Documentation and Have Declared

The officer reviews your documentation, confirms the quantity matches your prescription, and processes you through. This can take additional time — expect 20 to 40 minutes beyond normal processing — but it is not a legal crisis. The red channel exists precisely for this purpose. Customs officers who deal with declared controlled medications every day understand the difference between a tourist with a legitimate prescription and a trafficking situation.

If You Have Not Declared

If controlled medication is found and you went through the green channel without declaring it, you are now in an undeclared importation situation regardless of whether you have documentation. The failure to declare is itself an aggravating factor. Even if you subsequently produce documentation, the undeclared importation is already on the record. The customs officer's discretion about whether to process this as a documentation oversight or a criminal matter shifts materially once you have passed through the green channel.

If You Have No Documentation

This is the worst-case scenario. Controlled psychotropics found without documentation and without declaration are treated as unlawfully imported controlled substances. The process moves from customs to narcotics police (Sat Narkoba). Your medications are confiscated as evidence. You are detained for questioning. A police report is filed. Your consulate is notified. The outcome from this point depends on the quantity involved, your cooperation, and the specific officers and prosecutors involved — but none of the realistic outcomes are good.

The World Health Organization's guidance on controlled substance transport for personal medical use is consistent with Indonesian expectations: carry the original prescription, declare at customs, carry only a medically justified quantity. These are not extraordinary requirements. They are standard international travel practice for controlled medications.

The Departure Risk: Taking Locally-Purchased Benzos Home

A scenario that tourists consistently underestimate: buying benzodiazepines in Bali over the counter — whether from a pharmacy or from another source — and then attempting to take them home when you depart.

The departure process at Ngurah Rai involves security screening of all carry-on bags and, for flights to high-scrutiny destinations (Australia, the UK, the USA, Japan), additional departure screening by the Indonesian Narcotics Board (BNN) and customs. This screening is specifically designed to catch substances being exported from Indonesia, including locally purchased controlled substances.

The legal exposure at departure operates on two levels:

Indonesian Export Law

Exporting psychotropic substances from Indonesia without authorisation is an offence under UU 5/1997. Even if you purchased the diazepam from an Indonesian pharmacy — even if you somehow have a pharmacy label — exporting it without a valid prescription and export documentation is a controlled substance export offence. This carries similar penalties to the possession offence: up to 5 years, with aggravated provisions for larger quantities.

Your Destination Country's Import Law

When you land at home carrying Indonesian-labelled diazepam without documentation from your home country's prescribing doctor, your destination customs now sees undeclared psychotropics in your luggage. In Australia, the UK, the USA, and most EU countries, this triggers their own controlled substance import procedures. The Indonesian pharmacy label is not documentation that satisfies Australian Therapeutic Goods Administration requirements or UK Home Office requirements or US DEA import procedures. You may face action in both countries for the same tablets.

The practical lesson: benzodiazepines purchased in Bali without a prescription should not travel internationally in either direction. If you find yourself in a situation where you have purchased them and are wondering what to do before your departure, the cleanest option is to not take them through the airport.

Alternatives Available in Bali Without Restriction

If anxiety, sleep difficulty, or stress is the underlying issue you are trying to manage, Bali has a range of options that do not involve controlled substances or any legal risk.

Antihistamines for Sleep

First-generation antihistamines — diphenhydramine (the active ingredient in Benadryl, Nytol, and many OTC sleep aids) and doxylamine (Unisom in the USA) — are available in Bali pharmacies without a prescription. They cause significant drowsiness and are effective for occasional sleep difficulty. They are not appropriate for regular use and are not a substitute for prescription sleep medication for chronic insomnia, but for a holiday sleep disruption caused by jet lag or an uncomfortable environment, they are a legitimate and legal option. Local brands of diphenhydramine-containing products are inexpensive and widely available.

Melatonin

Melatonin supplements are available at larger pharmacies and health supplement stores in Bali without restriction. For jet lag specifically — which is one of the most common reasons tourists want sleep medication in Bali — melatonin is evidence-supported and appropriate. The WHO recognises sleep regulation as a meaningful component of overall mental health, and melatonin's role in circadian rhythm management is well-established. Standard doses of 0.5 to 5mg taken 30 minutes before the local bedtime are the typical recommendation for jet lag management.

Herbal and Traditional Supplements

Indonesia has a rich tradition of herbal medicine (jamu), and several preparations with mild calming effects are available throughout Bali. Products containing valerian root, passionflower, chamomile extract, and various traditional Indonesian botanical preparations are sold at pharmacies and health stores. These are not regulated as controlled substances and can be purchased and transported freely. Their efficacy is generally less potent than pharmaceutical anxiolytics, but for mild situational anxiety, they are worth considering.

Non-Pharmaceutical Approaches

Bali's wellness infrastructure is extensive. If the reason you are considering benzodiazepines relates to anxiety or stress management, the island offers world-class yoga centres (particularly in Ubud and Canggu), sound healing and meditation facilities, spa treatments, and breathwork practitioners. For situational holiday stress, these are appropriate tools. For genuine clinical anxiety disorders requiring pharmacological management, they are supplementary — not replacements — but they can reduce the intensity of symptoms meaningfully.

For stomach-related anxiety triggers, which are common in Bali due to changes in diet and intestinal adjustment, see our guide to treating Bali belly for specific OTC medications available locally without restriction.

Getting a Legitimate Prescription in Bali

If you have an established need for benzodiazepines and either run out during your trip, did not bring enough, or did not know you would need them before travelling, the legitimate pathway is to see a doctor in Bali and obtain an Indonesian prescription.

Finding a Doctor in Bali

Bali has a functioning medical infrastructure with international-standard clinics in the main tourist areas. The BIMC Hospital network (Kuta and Nusa Dua), Kasih Ibu Hospital in Denpasar, and SOS Medical Clinic in Seminyak all have English-speaking doctors and are familiar with treating international patients. International SOS and Global Doctor operate clinics specifically aimed at expatriates and tourists.

What to Expect from a Consultation

An Indonesian doctor will conduct a clinical assessment. They are not going to simply prescribe benzodiazepines on request because a tourist says they take them at home. They will ask about your medical history, your existing diagnosis, your previous prescriptions, and your specific situation. If you have documentation of your home prescription — even if it is not sufficient for customs purposes — bring it to the appointment as supporting clinical information.

An Indonesian doctor who determines that a benzodiazepine prescription is clinically appropriate will write you a valid Indonesian prescription. This prescription, combined with a properly labelled Indonesian pharmacy dispensing the medication, creates a lawful possession situation. Keep the prescription and the pharmacy label together. This documentation will also be necessary if you are stopped by police at any point during your remaining stay.

Cost Considerations

A consultation at an international clinic in Bali typically costs between USD 50 and USD 150, depending on the facility and the complexity of the assessment. The medication itself — diazepam, for example — is inexpensive at Indonesian prices if dispensed through the legitimate pharmacy system. Travel insurance that covers medical consultations will typically cover a clinic visit for this purpose; check your policy before assuming it will not be covered.

The Indonesia Ministry of Health's official health portal (kemkes.go.id) provides information on the Indonesian healthcare system and registered medical facilities. International clinics operating in Bali are licensed by the relevant provincial health authority and operate within the Indonesian regulatory framework.

Frequently Asked Questions

Is it actually illegal to buy diazepam at a Bali pharmacy without a prescription?

Yes. Diazepam is classified as a Group IV Psychotropic substance under Indonesian Law No. 5/1997 on Psychotropics. Indonesian pharmaceutical regulations require a valid prescription from a licensed doctor for any controlled psychotropic to be dispensed legally. A pharmacy selling diazepam without a prescription is violating Indonesian law, and a person purchasing and possessing diazepam without a prescription is in possession of a controlled substance without legal authorisation — which is an offence under Article 62 of UU 5/1997, carrying a maximum penalty of 5 years imprisonment. The fact that some pharmacies sell it without a prescription does not change either the law or your personal legal exposure.

What is the difference between benzodiazepines and narcotics under Indonesian law?

These are regulated under completely separate laws. Narcotics — cocaine, heroin, methamphetamine, MDMA, cannabis, psilocybin — are regulated under Law No. 35/2009 on Narcotics, which carries penalties up to and including the death penalty for trafficking quantities. Benzodiazepines are regulated under the older Law No. 5/1997 on Psychotropics as Group IV Psychotropics. The penalties under UU 5/1997 are serious (up to 5 years possession, up to 15 years for distribution offences) but are categorically different from the penalty scale under UU 35/2009. Being caught with unlawfully possessed diazepam is not the same legal situation as being caught with narcotics. However, "less severe than a potential death sentence" is still a very serious situation that should not be minimised.

Can I bring Xanax (alprazolam) to Bali from my home country?

Yes, if you bring it correctly. Alprazolam is a Group IV Psychotropic under Indonesian law and its importation for personal medical use is lawful if you: carry it in the original commercially labelled pharmacy packaging, carry a doctor's letter explaining the medical necessity and quantity (ideally with a certified Bahasa Indonesia translation), declare it on your customs arrival form and go through the red channel, and do not bring more than approximately 30 days' supply (the generally accepted limit for personal import without a formal BPOM import permit). Doing all of this correctly means your possession is lawful and you have documentation to demonstrate it. Missing any of these steps — particularly failing to declare — creates significant legal risk.

What should I do if police ask about medication I'm carrying in Bali?

Stay calm and cooperative. Do not attempt to conceal the medication or lie about what it is. Produce your prescription documentation immediately. If you have a valid Indonesian prescription or valid import documentation from customs arrival, present it clearly and explain the situation. Do not offer money — attempting to bribe police officers in Bali is itself a criminal offence and will dramatically worsen any situation you are in. If you are detained, request consular notification immediately. You have the right to contact your embassy or consulate. Indonesia is a signatory to the Vienna Convention on Consular Relations, which requires Indonesian authorities to notify your consulate upon request when a foreign national is detained. For a full walkthrough of Indonesian arrest and detention procedures, see our guide to getting arrested in Bali.

Are there sleep medications I can buy in Bali without a prescription?

Yes. First-generation antihistamines such as diphenhydramine are available over the counter at Bali pharmacies without restriction and cause significant drowsiness useful for sleep. Melatonin supplements are also available without prescription and are appropriate for jet lag management. Herbal preparations including valerian-based products and traditional Indonesian jamu formulations for calming are available freely at pharmacies and health stores. None of these are controlled substances and none carry any legal risk in purchasing, possession, or travel. What is not available without a prescription in Indonesia are the benzodiazepine-class sleep medications: nitrazepam (Mogadon), temazepam, triazolam, and zolpidem (Stilnox/Ambien) are all Group IV Psychotropics under UU 5/1997 and require a valid prescription for lawful possession.

What happens if customs finds my unlabelled benzodiazepine tablets?

Unlabelled tablets found during customs inspection — tablets that have been removed from their original pharmacy packaging and placed in a pill organiser, small bag, or any other container — cannot be immediately identified by customs officers. The standard response is to detain the passenger and the substance for testing. You will be held in the customs area while the tablets are tested to determine what they contain. If they test positive for a controlled psychotropic substance, the situation escalates to narcotics police involvement. Even if you can subsequently explain that these are prescription benzodiazepines, the absence of original labelling will be treated as an attempt to conceal the nature of the substance, which is an aggravating factor in any subsequent proceedings. Always travel with medications in their original, labelled pharmacy containers. This is the most basic and most important rule for travelling internationally with controlled medication.

I bought diazepam from a pharmacy in Bali without a prescription. What should I do now?

Your options depend on your specific situation. If you still need the medication medically, the cleanest path is to visit an international clinic in Bali, explain your situation honestly to the doctor, and get a proper Indonesian prescription if the doctor determines it is medically appropriate. Keep the prescription and the pharmacy packaging together for the remainder of your stay. If you do not medically need the remaining tablets, the safest course is to not take them through any airport — Indonesian departure or your arrival airport at home. Indonesian export of controlled psychotropics without authorisation is an offence, and your destination country's customs operates independently of whatever happened in Bali. This is a situation to be handled carefully and honestly, not one where creative solutions are likely to help.
