Drug Possession in Vietnam: Article 249 of the Penal Code and Your Defence

Lawyer UnilawReading time: 8 min

Vietnam treats illegal possession of narcotics as an offence in its own right, separate from trading, transporting or producing them. It is Article 249 of the Penal Code, and unlike theft it has no non-custodial bracket: the lowest penalty the Article provides is three years’ imprisonment. If you are looking for a “drug possession attorney” in Vietnam, the questions that will decide the case are the substance, the measured quantity, and the purpose the file attributes to you.

1. Article 249 is about possession without a commercial purpose

Article 249(1) applies to a person who illegally stores narcotics not for the purpose of trading, transporting or illegally producing them. That qualification is the boundary of the Article. If the file alleges a commercial or production purpose, the charge moves to a different article with a different, heavier structure. A great deal of defence work in Vietnamese narcotics cases is therefore about what the evidence actually supports on purpose — packaging, scales, messages, cash, the account of the arrest — rather than about possession itself, which is often not in dispute.

2. The quantity thresholds that bring Article 249 into play

Article 249(1) is not open-ended. It applies in one of the following situations. The first is a record: the person has already been administratively sanctioned for conduct under this Article, or has an unexpunged conviction for this offence or for one of the offences in Articles 248, 250, 251, 252 or 256a, and offends again. The remainder are quantities:

opium resin, cannabis resin or coca paste: from 1 gram to under 500 grams;
heroin, cocaine, methamphetamine, amphetamine, ketamine, fentanyl, MDMA or XLR-11: from 0.1 gram to under 5 grams;
coca leaf, khat leaf, or the leaves, roots, stems, branches, flowers or fruit of the cannabis plant or other narcotic-bearing plants designated by the Government: from 1 kilogram to under 10 kilograms;
dried opium poppy fruit: from 5 to under 50 kilograms; fresh: from 1 to under 10 kilograms;
other solid narcotics: from 1 gram to under 20 grams; other liquid narcotics: from 10 to under 100 millilitres;
two or more narcotics whose combined quantity is equivalent to one of the thresholds above.

These figures are the statute, not a rule of thumb, and they are why the laboratory result is the centre of the file. A measurement at or just above 0.1 gram of methamphetamine is a different legal position from a trace that cannot be weighed, and the composition analysis — what proportion of the seized material is the controlled substance — can move the case across a threshold.

3. Three to five years is the entry bracket, not the maximum

Article 249(1) carries imprisonment from 3 to 5 years. Clause 2 raises it to 5 to 10 years for a list of circumstances: an organised offence, offending twice or more, abuse of position or powers, acting under the name of an agency or organisation, using a person under 16 in the offence, and the next quantity band — for example heroin, cocaine, methamphetamine, amphetamine, ketamine, fentanyl, MDMA or XLR-11 from 5 grams to under 30 grams. Higher clauses follow for larger quantities. The practical consequence is that the difference between clause 1 and clause 2 is usually a handful of grams or a single characterisation, and it costs at least two more years.

4. Article 65 and the arithmetic of a suspended sentence

Article 65 of the Penal Code allows a suspended sentence only where the imprisonment imposed does not exceed 3 years. Because Article 249(1) starts at 3 years, a suspended sentence is arithmetically possible only where the court imposes the statutory minimum exactly — and is out of reach entirely under clause 2. This is the single most important thing for a family to understand early, because it changes what “a good outcome” means and it puts the weight on the mitigating circumstances and on keeping the case in clause 1.

Article 51 lists the mitigating circumstances. The ones reachable here are mostly about conduct after the event: voluntarily making good or remedying consequences, offending for the first time in a less serious case, acting under threat or coercion, limited capacity for awareness not caused by one’s own fault, being a pregnant woman, or being 70 or over. Article 54 permits a penalty below the lowest limit of the applicable bracket in the circumstances it defines. Article 29 sets out the grounds on which criminal responsibility may be waived altogether, including where the offender voluntarily surrenders before the act is discovered, gives a full account and contributes effectively to the detection and investigation of the offence.

5. Minors and Article 249

Article 12 of the Penal Code lists Article 249 among the articles for which a person aged 14 to under 16 can bear criminal responsibility, for very serious and especially serious offences. Where the accused is under 18, the Law on Juvenile Justice No. 59/2024/QH15, in force from 1 January 2026, governs the procedure and the outcomes, including the twelve diversion measures in its Article 36 and the reduced imprisonment caps in its Article 119.

6. What the file has to prove, and what it cannot rest on

Article 13 of the Criminal Procedure Code No. 101/2015/QH13 states the presumption of innocence and requires the competent authority to conclude that the person is not guilty where the grounds for accusation cannot be established through the Code’s procedure. Article 98 is decisive in narcotics cases where the main document in the file is a statement taken at the scene: an admission by the accused may be treated as evidence only if it is consistent with the other evidence, and may never be the sole basis for a conviction.

Article 183 governs interrogation. The investigator must notify the procurator and the defender of the time and place, must explain the accused’s rights under Article 60 before the first interrogation and record that in the minutes, must question co-accused separately without letting them meet, and must not interrogate at night unless it cannot be postponed and the reason is recorded. Where a statement in a narcotics file was taken at night, that entry in the minutes is worth reading.

7. Your rights, and when a lawyer can actually be present

Articles 58, 60 and 61 of the Criminal Procedure Code set out the rights of a person held or arrested, of the accused and of the defendant. All three include the right to be told the reason, to have rights explained, to present evidence and requests, to comment on the evidence against them, and expressly not to be compelled to give a statement against oneself or to admit guilt. Article 16 obliges the authorities to notify, explain and ensure the exercise of the right to defence.

Article 74 fixes the entry point: a defender takes part from the moment charges are laid, and where the person is arrested or held in custody, from the moment they arrive at the investigating body’s premises or the custody decision is issued. Article 73 lists the defender’s powers, including being present when statements are taken and during interrogation and attending confrontation and identification. Article 78 requires registration in every case and lists the documents to be produced. Article 76 makes appointment mandatory where the maximum penalty is 20 years, life imprisonment or death, or where the accused has a physical or mental defect or is under 18.

8. Foreign nationals arrested in Vietnam

Article 5 of the Penal Code applies the Code to every offence committed on Vietnamese territory, and to conduct on aircraft and ships of Vietnamese nationality and in Vietnam’s exclusive economic zone and continental shelf. A foreign visitor, worker or resident found in possession of narcotics in Vietnam is therefore dealt with under Article 249. Article 5(2) qualifies this only for persons entitled to diplomatic or consular immunity.

Article 29 of the Criminal Procedure Code provides that proceedings are conducted in Vietnamese and that a participant may use their own language with an interpreter provided. Every statement in the file exists in a Vietnamese version, and verifying that the Vietnamese text matches what was said — particularly on the question of purpose — is part of the defence work, not a formality.

9. Speak to UniLaw before the first statement is signed

In an Article 249 case the outcome is largely set by three things: the measured quantity, whether the file alleges a commercial purpose, and what the earliest statements say. All three are most easily addressed while the investigation is open. If you or a family member has been arrested in connection with narcotics in Vietnam, contact UniLaw. We will tell you which clause of Article 249 the file is heading for and what is realistically available — including whether a suspended sentence is arithmetically possible at all.
