Cannabis Law and Access in Vietnam

Forty-seven countries have now introduced some form of regulated cannabis access. Vietnam is not one of them. That number tends to surprise people who've spent time in Southeast Asia and noticed the casual availability of cannabis products in tourist areas , but the gap between street-level reality and the legal framework is wide, and the consequences of mistaking one for the other are severe.

I've been tracking regulatory developments across the Asia-Pacific region for a few years now, mostly because Australia's own access architecture , the Special Access Scheme, the Authorised Prescriber pathway, TGA scheduling , gets discussed in near-complete isolation from what's happening in neighbouring jurisdictions. Vietnam is worth understanding for exactly that contrast.

The legal foundation: what the law actually says

Vietnam's primary instrument is the Law on Narcotic Substances (Luật Phòng, chống ma túy), most recently revised in 2021 and effective from 1 January 2022. Cannabis; including all parts of the Cannabis sativa plant and any preparations derived from it, is classified under List I of the country's controlled substances schedule. List I is the most restrictive category. It covers substances deemed to have no accepted medical use and high potential for dependency, and it broadly mirrors what the United Nations' 1961 Single Convention on Narcotic Drugs calls Schedule IV (the most restrictive level).

There is no carved-out medical exemption. There is no equivalent of Australia's Schedule 4 or Schedule 8 pathway for cannabis-based medicines. There is no provision for domestic research licences that would permit clinical investigation of cannabidiol or tetrahydrocannabinol outside of a tightly controlled (and, to date, non-existent in practice) government programme.

Possession, use, cultivation, trafficking and import are all prohibited. Penalties scale sharply with quantity. Trafficking offences involving large amounts can attract the death penalty under Article 251 of the Penal Code, a provision that remains in active use.

Enforcement and the tourist reality

Here's the tension that anyone who has travelled through Hanoi's Old Quarter or Ho Chi Minh City's Bui Vien Street will recognise: small-scale cannabis use exists visibly in backpacker zones, and police enforcement in those areas can appear selective or inconsistent. Some travellers interpret this as de facto tolerance. It is not.

Selective enforcement is not decriminalisation. Vietnamese law makes no formal distinction between personal use and supply at the definitional level, and enforcement priorities can shift without notice. The Australian Department of Foreign Affairs and Trade's Smartraveller advice is unambiguous on this point: Australians arrested on drug offences in Vietnam face the Vietnamese legal system, and consular assistance cannot change the outcome of a prosecution.

I'll be honest: the visibility of cannabis in tourist areas is, in my view, partly a function of how enforcement resources are allocated; not evidence that the law is soft. The underlying statute is unambiguous and the penalties are real.

No medical cannabis framework, and why that matters scientifically

The absence of a regulated pathway has a downstream consequence that rarely gets discussed: it forecloses legitimate clinical research. Understanding how cannabinoids interact with the endocannabinoid system, including how CB1 and CB2 receptors behave in different human populations; requires institutional research frameworks that Vietnam currently does not have for cannabis. This matters because pharmacogenomic variation across Southeast Asian populations is genuinely understudied in cannabinoid science.

It also means there is no legal mechanism for authorised importation of cannabis medicines. A patient travelling to Vietnam from Australia with a legally prescribed cannabis product, dispensed under the TGA's regulatory framework, would be carrying a controlled substance into a jurisdiction with List I prohibition. The Australian prescription carries no legal weight at the Vietnamese border. None.

Regional context: where Vietnam sits

Vietnam's position is not unusual in the ASEAN bloc. Thailand is the notable outlier; it removed cannabis from its narcotics list in 2022, though the regulatory situation there has since become complicated and contested. Most other ASEAN members maintain strict prohibition: Singapore, Malaysia, Indonesia, Philippines, and Laos all carry severe penalties including, in several cases, mandatory minimum sentences and capital punishment for trafficking.

Vietnam sits firmly in the majority position. There have been periodic academic discussions within Vietnamese public health circles about harm reduction approaches to drug policy more broadly, but as of the current legislative cycle those have not produced any movement on cannabis specifically.

The 2021 revision to the Law on Narcotic Substances introduced some changes to how addiction is treated, moving toward a public health framing for dependency in certain circumstances, but this did not alter the scheduling of cannabis or create any pathway for regulated access. The two things are sometimes conflated in commentary, and it's worth being precise: harm reduction framing for users is distinct from regulatory reform of the substance's legal status.

Hemp and industrial cannabis

There is one partial exception worth noting. Vietnam has a small history of hemp cultivation in the northern highlands; historically associated with ethnic minority communities in provinces like Hà Giang and Lào Cai, where hemp has traditional textile and cultural uses. This practice has existed in a complicated legal grey zone. The Vietnamese government has at various points tolerated traditional hemp cultivation by specific communities whilst maintaining that cannabis cultivation is otherwise prohibited.

This is not a licensed industrial hemp framework of the kind that exists in Australia, the EU, or the US. There is no defined THC threshold below which hemp is treated as a separate crop. There is no commercial hemp industry with associated regulatory oversight. The traditional cultivation that exists does so in a context of cultural recognition and practical non-enforcement rather than legal authorisation, a different thing entirely.

Spent a decent chunk of last Saturday with some old survey maps of the Hà Giang region, I collect topographic maps from the French colonial survey period, completely unrelated hobby; and it was striking how consistently hemp cultivation appeared in land-use records for those highland provinces across the 20th century. The plant's presence there predates the modern legal framework by generations. Anyway.

What this means for Australian travellers and researchers

If you're an Australian researcher with an interest in cannabinoid science, say, studying how anandamide metabolism differs across populations, or examining terpene profiles in traditional plant varieties, Vietnam's framework makes formal collaborative research extremely difficult to structure. Any work involving controlled substances would require engagement with Vietnam's Ministry of Health and Ministry of Public Security, and there is no established pathway for doing so with cannabis specifically.

For Australian travellers: do not carry cannabis products into Vietnam, regardless of their legal status at home. Do not assume that visible use in tourist areas reflects the law's actual position. The Australian Government's Smartraveller register is worth checking before travel to any country in the region.

And for context on how differently Australia has approached this: the contrast with the TGA's access architecture; including the Special Access Scheme and the ARTG listing pathway for approved cannabis medicines, is stark. Both systems are responses to the same plant chemistry; the policy divergence is almost total.
