The legal status of cannabis is among the most complex and rapidly evolving areas of drug policy worldwide. A plant that was subject to international prohibition treaties in the 1960s is now legally regulated in a growing number of countries and sub-national jurisdictions. This page provides a structured overview of the global legal landscape for cannabis, organized by international framework, national approaches, and key distinctions in legal categories.

Three United Nations conventions form the foundation of international cannabis regulation:
| Convention | Year | Key Provisions on Cannabis |
|---|---|---|
| Single Convention on Narcotic Drugs | 1961 | Classified cannabis as a Schedule I and Schedule IV substance, requiring parties to limit its use to medical and scientific purposes. Required parties to "abolish" cannabis within 25 years. |
| Convention on Psychotropic Substances | 1971 | Did not explicitly schedule cannabis or THC (unlike synthetic cannabinoids), leaving regulation primarily to the 1961 Convention. |
| Convention Against Illicit Traffic | 1988 | Required parties to criminalize the possession, distribution, and cultivation of cannabis for non-medical/scientific purposes. |
In December 2020, the UN Commission on Narcotic Drugs (CND), following a World Health Organization (WHO) recommendation, removed cannabis and cannabis resin from Schedule IV of the 1961 Single Convention while keeping them in Schedule I. This change:
Countries that have legalized recreational cannabis (e.g., Canada, Uruguay) do so in tension with — and arguably in violation of — their obligations under the 1961 Convention. However, the UN has not imposed sanctions or meaningful consequences, reflecting a broader shift toward allowing national sovereignty on drug policy.
Understanding cannabis legality requires several key distinctions:
| Category | Description |
|---|---|
| Medical cannabis | Cannabis or cannabis-derived products prescribed or recommended for therapeutic purposes. Legal in more jurisdictions than recreational use, often under strict regulatory frameworks. |
| Recreational (adult-use) cannabis | Cannabis available for purchase and use by adults without a medical indication. Legal in fewer jurisdictions, typically with regulatory frameworks for production, sale, and taxation. |
| Term | Definition | Practical Effect |
|---|---|---|
| Decriminalization | Possession of small amounts remains a civil offense (like a traffic ticket) rather than a criminal offense. Production and sale typically remain illegal. | Reduced penalties for users; criminal penalties for dealers and growers may remain. |
| Legalization | Production, sale, and possession are legal under a regulatory framework. | Government-regulated market with licensing, quality control, taxation, and age restrictions. |
| Depenalization | No penalties (criminal or civil) for possession of personal-use amounts. Informal tolerance by law enforcement. | Minimal enforcement for personal possession; legal ambiguity remains. |
Many jurisdictions distinguish between hemp and cannabis (marijuana) based on THC content:
| Category | Typical Legal Definition | Key Note |
|---|---|---|
| Hemp | Cannabis containing 0.3% THC or less (US standard) or 0.2% THC or less (EU standard) | Often legal to grow and process; source of CBD products |
| Cannabis/Marijuana | Cannabis exceeding the hemp THC threshold | Subject to stricter controls or prohibition |
This distinction has created a significant legal loophole for CBD products in many jurisdictions.

The United States presents one of the most complex legal landscapes due to the conflict between federal and state law.
| Attribute | Detail |
|---|---|
| Classification | Schedule I controlled substance (Controlled Substances Act, 1970) |
| Definition | "No currently accepted medical use and a high potential for abuse" |

As of early 2026, the state-level landscape is as follows:
| Category | Approximate Number | Notes |
|---|---|---|
| Recreational + Medical legal | 24+ states + DC | Includes California, Colorado, Washington, New York, New Jersey, Illinois, Michigan, and others |
| Medical only | 15+ states | Includes Florida, Ohio, Pennsylvania, and others |
| CBD-only laws | A small number of states | Limited CBD access for specific conditions |
| Fully illegal | A small number of states | No medical or recreational framework |
::: warning State Law Volatility
The above numbers are approximate and change frequently. New states legalize regularly, and some states have existing programs under legal challenge. Always check current state law.
:::
Despite federal prohibition, enforcement in states with legal programs has been guided by executive branch policy memoranda:
| Policy | Year | Description |
|---|---|---|
| Cole Memorandum | 2013 | Directed federal prosecutors not to prioritize cannabis enforcement in states with robust regulatory frameworks. Rescinded in 2018. |
| Rohrabacher-Farr Amendment | 2014 (annual renewal) | Prohibits DOJ from using federal funds to interfere with state medical cannabis programs. |
| Current practice | 2021-present | De facto tolerance of state-legal programs under the Biden administration, though no formal policy guarantees this. |
Cannabis businesses in state-legal markets face significant financial challenges:
Medical cannabis is legal in a significantly larger number of countries than recreational cannabis:
| Region | Countries with Medical Cannabis Programs (examples) |
|---|---|
| Europe | Germany, Italy, Netherlands, Poland, Czech Republic, United Kingdom, Malta, Luxembourg, Cyprus |
| Americas | United States (state-level), Canada (also recreational), Uruguay (also recreational), Brazil, Colombia, Argentina, Chile, Peru, Jamaica |
| Oceania | Australia, New Zealand |
| Africa | South Africa, Zimbabwe, Lesotho, Rwanda, Morocco (limited) |
| Asia | Thailand, Israel, South Korea (very restricted), Japan (CBD only) |
| Middle East | Israel (research and limited medical) |
::: info Medical Program Variation
"Medical cannabis legal" encompasses a wide range of programs — from full pharmacy access to flower products, to restricted CBD-only access for specific conditions, to research-only frameworks. The scope and accessibility vary dramatically between countries.

::: danger Critical Warning
Transporting cannabis across international borders is illegal under international law and the laws of virtually all countries. This applies even when traveling between two jurisdictions where cannabis is legal.
| Scenario | Legal Risk |
|---|---|
| Flying internationally with cannabis | Very High — federal and international law violations |
| Driving across borders with cannabis | Very High — border crossings enforce federal law |
| Mailing cannabis across state/national borders | Very High — postal service is federal jurisdiction; adds trafficking charges |
| Possessing cannabis on federal property (US) | High — federal land (national parks, military bases) enforces federal law regardless of state legality |
The legal status of hemp-derived products has created a complex sub-category of cannabis law:
| Region | Status |
|---|---|
| United Kingdom | CBD legal as Novel Food; THC limited to < 0.2% |
| Australia | Low-dose CBD available over-the-counter; higher doses require prescription |
| Japan | CBD legal; THC strictly prohibited with severe penalties |
Countries and jurisdictions that have decriminalized cannabis possession (but not legalized it):
| Country | Year | Details |
|---|---|---|
| Portugal | 2001 | All drugs decriminalized; cannabis possession up to 25g is administrative |
| Spain | Various | Personal use and cultivation decriminalized; cannabis social clubs exist in a legal gray area |
| Belgium | 2003 | Possession of up to 3g for adults is depenalized |
| Czech Republic | 2010 | Possession of up to 10g is a civil offense |
| Italy | Various | Small amounts for personal use are administrative offenses, though legal interpretation varies |
| Australia (various states) | Various | Several states have civil penalty schemes for minor cannabis offenses |
| Estonia | 2002 | Small amount possession is misdemeanor, not crime |
| Russia | — | NOT decriminalized — possession of any amount is a criminal offense |
| China | — | NOT decriminalized — severe penalties including death penalty for trafficking |
Several jurisdictions that have legalized recreational cannabis have implemented social equity programs designed to:
