Marijuana in Portugal - a decriminalization model that changed the world (FAQ)
Marijuana in Portugal: answers to frequently asked questions and what research says. u Bucha.
In 2001, Portugal did something that the drug world considered madness: it decriminalized the possession of all drugs - including marijuana, heroin, and cocaine - for personal use. Instead of punishing with imprisonment, the country opted for dissuasion commissions and healthcare. More than two decades later, data EMCDDA show that the experiment has been a success: the number of overdose deaths has drastically fallen, and the addiction rate has decreased to below the EU average. This article explains how the Portuguese model works, what is specifically allowed and what is not - and what Poland and Europe can learn from it.
KEY INFORMATION
• Portugal decriminalized the possession of all drugs for personal use in 2001 with Law No. 30/2000 - trade and production remain crimes (EMCDDA, Drug Policy Profile Portugal).
• The limit for marijuana: up to ~25 g of herb or ~5 g of hashish without criminal liability.
• The number of overdose deaths in Portugal fell from ~80 per million inhabitants (2001) to ~3 per million (2017) - the lowest level in the EU.
• CBD is legal with a THC content below 0.2%; medical marijuana has been available since 2019 by prescription.
Ustawa nr 30/2000 - czym jest model dekryminalizacji?
The Portuguese model is based on a fundamental distinction: drug trafficking remains a criminal offense prosecuted to the fullest extent of the law, while possession for personal use becomes an administrative offense. This seemingly minor change makes all the difference in practice - from prisons to clinics, from police to therapeutic commissions.
Law No. 30/2000 of November 29, 2000 (effective July 1, 2001) sets the quantity limits considered "possession for personal use" for each drug. For marijuana, this is approximately a 10-day supply, which according to health ministry guidelines corresponds to ~25 g of dried flower or ~5 g of hashish (EMCDDA, Drug Policy Profile Portugal). Possession up to this amount directs a person to the Commission for the Deterrence of Drug Addiction, rather than to the criminal court.
Important: decriminalization is not legalization. Buying, growing, and selling marijuana remains a crime. Decriminalization only applies to the consumer holding the drug for personal use. This detail is often misunderstood by tourists visiting Lisbon or Porto.
How do the Commissions for the Deterrence of Drug Addiction (CDT) work?
Comissões para a Dissuasão da Toxicodependência (CDT) are the heart of the Portuguese model - multidisciplinary panels operating in every administrative region of the country. The composition of the commission consists of three people: a lawyer or social worker, a psychologist or sociologist, and a healthcare worker or representative of medical professions.
When the police detain a person with a drug below the limit, they are referred to the CDT - usually, the summons appears within 72 hours. Before the commission, the person presents their circumstances. The commission assesses three issues: whether the person is dependent, whether they use the drug recreationally, and what the risk of returning to drugs is. Based on this assessment, the CDT makes a decision.
Possible CDT decisions include: a warning (most common for first contact with a recreational user), an administrative fine (rare, especially in cases of addiction), a ban on appearing in certain places or with certain people, and in cases of confirmed addiction - referral to a treatment or therapy program. Refusal to accept treatment may result in an administrative penalty, but not imprisonment.
| Situation | Proceedings | Possible penalty |
|---|---|---|
| Possession ≤25 g of marijuana | CDT (administrative commission) | Warning, fine, therapy |
| Posiadanie >25 g marihuany | Criminal proceedings | Prison sentence (trafficking) |
| Trafficking / production | Criminal proceedings | Up to 12 years in prison |
| Cultivation for personal use | Gray area (lack of clear interpretation) | Depending on the quantity and circumstances |
| CBD (THC <0,2%) | Legal | No penalty |
Does the Portuguese model work? Data after 25 years
After more than two decades of the decriminalization model, the data is clear. Dramatic overdose death statistics are the most cited outcome: in 2001, Portugal had one of the highest rates in Europe - about 80 deaths per million inhabitants. By 2017, this rate had dropped to about 3 per million, representing the lowest level in the entire European Union - with the European average being over 20 per million (EMCDDA, Drug Policy Profile Portugal).
HIV among people who inject drugs fell from 52% of new HIV infections in 2000 to below 7% in 2015. Prisons in Portugal are not overcrowded with drug users - about 20% of prisoners have drug-related sentences, while before 2001 it was over 40%.
A often overlooked aspect of the success of the Portuguese model: Portugal simultaneously increased investments in addiction treatment and prevention alongside legal changes. The CDT programs alone, without a healthcare system, would likely not have yielded such good results. This is a lesson for countries considering simply abolishing penalties without building supportive infrastructure - decriminalization alone is not enough. The Portuguese model is a package: legal change plus real healthcare.
These results are widely cited by organizations such as Drug Policy Alliance and WHO as evidence that drug decriminalization combined with investments in healthcare reduces harm more effectively than punitive policies. The Portuguese model is being studied by governments around the world - from Scotland to Colombia - although its full replication also requires a similar level of investment in social services.
Medical marijuana and CBD in Portugal
Medical marijuana became available in Portugal in 2019 under Decree-Law No. 8/2019. Patients with certain conditions can obtain a prescription from a specialist, and cannabis medications are dispensed at pharmacies. Indications include, among others, multiple sclerosis, treatment-resistant epilepsy, neuropathic pain, and chemotherapy-induced nausea. Access is possible but limited - the list of doctors authorized to prescribe is short, and products are neither cheap nor reimbursed.
CBD in Portugal is subject to EU law with local modification: the THC limit is 0.2% (lower than the EU's 0.3%). Following the CJEU ruling in 2020 (C-663/18), CBD products are sold legally. The CBD market in Lisbon and Porto has significantly developed since 2021 - many shops have opened, and products are also available in pharmacies.
Frequently Asked Questions
Is marijuana legal in Portugal?
No, marijuana is not legal in Portugal - but it has been decriminalized since 2001. Law No. 30/2000 decriminalized the possession of all drugs (including marijuana) for personal use in amounts up to a 10-day supply. This means that possessing a small amount is not a criminal offense but an administrative infraction handled by the CDT. Trafficking and production remain criminal offenses (EMCDDA, Drug Policy Profile Portugal).
How much marijuana can one possess in Portugal without criminal penalties?
Law No. 30/2000 sets a limit of a 10-day supply for each drug. For marijuana, official guidelines set this limit at about 25 grams of flower or 5 grams of hashish. Possession above these limits qualifies for criminal proceedings for trafficking. Below the limit, a person is referred to the Drug Addiction Deterrence Commission (CDT).
How does the Drug Addiction Deterrence Commission (CDT) work in Portugal?
CDT consists of multidisciplinary panels made up of a lawyer, psychologist, and medical worker. Anyone caught with drugs below the limit appears before such a commission. The CDT assesses whether the person is addicted or using recreationally and decides: warning, fine, ban from certain places, or referral to addiction treatment.
Does the Portuguese model work? What are the effects?
The effects are positive. According to EMCDDA the number of overdose deaths in Portugal fell from about 80 per million inhabitants (2001) to about 3 per million (2017) - the lowest level in the EU. The addiction rate has decreased to below the European average. HIV among intravenous drug users dropped from 52% of new infections to below 7%.
What is the status of CBD in Portugal?
CBD in Portugal is legal. CBD products can be sold provided that the THC content is below 0.2% (a lower threshold than in the EU - 0.3%). Following the CJEU ruling in 2020 (C-663/18), Portugal adjusted its interpretation of the law. Medical marijuana has been available since 2019 with a prescription from a specialist (EUR-Lex C-663/18).
Is Portugal planning full legalization of marijuana?
As of 2026, Portugal does not plan full legalization of recreational marijuana. There is political debate, but after the 2024 elections, in which the center-right PSD won, the prospects for legalization seem distant. The decriminalization model remains an unaltered foundation of drug policy.
