How Vietnam Enforces Cannabis Possession Laws

A few grams of cannabis in a bag, found at a checkpoint or in a hostel room in Vietnam, is not a ticket-and-fine situation. The Criminal Code treats possession of narcotics as a prosecutable offense, and cannabis is on the list.

The details of Vietnam's 2025 amendment below come from one unofficial source, a user-submitted bug report on an open-source cannabis-law tracker, not from the official legal text.

Where Cannabis Sits in Vietnamese Law

Vietnam classifies cannabis among prohibited narcotic substances. There is no legal recreational market and no licensed retail system of the kind found in some other countries.

The Criminal Code organizes drug offenses by activity rather than by substance alone. Possession falls under Article 249. Trafficking and transport, production, and the illegal cultivation of cannabis and other narcotic plants are handled as separate offenses, each with its own penalty structure.

A second layer sits on the administrative side. The Law on Drug Prevention and Control governs how people who use drugs are identified and handled outside criminal court. Its current version, and whether 2025 changes touch cannabis, are not covered here.

This section is a general outline of the framework, not a legal reading. The primary sources are thuvienphapluat.vn, vbpl.vn, and Ministry of Public Security materials.

Article 249: The Possession Offense

Article 249 covers illegal possession of narcotic substances. Cannabis resin and cannabis plant material fall within its scope.

The article is built in brackets. Penalties rise with the weight of the substance, and the higher brackets carry far longer prison terms than the entry level. A small amount and a large stash are charged in very different brackets.

One unofficial source reports that the first bracket begins at 1 g of cannabis resin or 1 kg of plant material. That is described as the older threshold, the one a legal-tracking file had been quoting. It has not been checked against the current text.

Upper-bracket weights and sentences are left out because no confirmed official source was found for them.

Trafficking, transport and production sit under separate articles, with considerably harsher exposure than simple possession. Where a case lands depends on what prosecutors can show about quantity and purpose, not only on what was found.

What Law 86/2025/QH15 Reportedly Changed

The most concrete recent claim comes from a user-submitted bug report on the cannabis-freedom-index GitHub project. It says Law No. 86/2025/QH15 took effect on 1 July 2025 and amended Article 249(1) to a range of 3 to 5 years, replacing the earlier 1 to 5 years for the first criminal possession bracket.

The same report indicates the weight threshold for that bracket was not changed by the amendment, though it does not prove that point.

It is a secondary, unofficial report, not a legal authority. Its author calls the 3-year minimum confirmed, but that is not a citation to the statute.

If the report is right, the floor of the range moves from one year to three, which narrows the room for a lenient outcome at the entry level of the possession offense. A judge facing a first-bracket case would have less distance between the minimum and the maximum.

How Enforcement Works in Practice

In general terms, a drug case in Vietnam begins with investigation by police. Prosecution is handled by the People's Procuracy, and trial takes place in a People's Court.

Criminal prosecution is not the only track. Drug use can also be handled administratively, through fines or rehabilitation measures under separate rules. Which track applies in a given case depends on the facts and the quantity involved.

No recent enforcement statistics, arrest counts or figures on cases involving foreign nationals turned up, so how often possession ends in prison rather than rehabilitation is unknown.

Readers who want data have two obvious places to start:

• Ministry of Public Security announcements on drug cases
• Vietnamese state media reports on drug arrests and trials

Those sources report individual cases and periodic summaries, which is the closest thing to a public record available.

What Travelers and Residents Should Take From This

Even a small quantity can lead to criminal charges in Vietnam. That includes products bought abroad: edibles, vape cartridges, or CBD items that may contain THC. A label that says legal where it was sold does not carry weight at a Vietnamese border or checkpoint.

Foreigners are subject to Vietnamese law while in the country. Consular staff can generally check on a detained citizen and help with contact and documents, but they cannot override local criminal procedure.

No verified legal pathway for hemp or medical cannabis turned up, and nothing on proposals or pilots.

Because the law reportedly changed recently, anyone carrying cannabis-derived products in or near Vietnam should consult a qualified Vietnamese lawyer.

The open questions are the current weight thresholds and whether the three-year minimum took effect as reported. Until the amending text is read directly, the first-bracket range of 1 to 5 years versus 3 to 5 years remains unsettled.
