Marijuana in the USA: what is allowed and what are the risks (2026)

This entry describes only the federal law of the United States. State law is separate and very different, and the material we are working on does not cover it, so you will not find answers here to the question of what is allowed in a specific state.

This disclaimer is more important than usual, as the entire American paradox lies in the divergence between these two orders. Below is what follows from the text of the federal code and from the rule announced in April 2026.

Legal status checked on September 5, 2026, in the federal code and in the official journal. This is a description of federal regulations, not legal advice and does not describe state law.

Is possession of marijuana in the USA punishable?

Federally yes, and this is the essence of the American paradox. Marijuana is listed in Schedule I of the Controlled Substances Act, alongside LSD, mescaline, and peyote, and a separate entry is the extract of marijuana. Schedule I means no recognized medical use. The schedule does not provide for any exceptions for any state.

The consequence is formally simple. Possession remains a federal crime regardless of what state law says where it occurred. The federal schedule knows no territorial exceptions and does not refer to state legislation.

Practice diverges from this record, and this is where all the confusion comes from. A legal store operating under a state license does not change the federal status of the goods it sells; it only operates in a different legal order.

We therefore repeat the disclaimer from the beginning, as it is the most important here. It is not possible to answer based on this entry what is allowed in California or Colorado, and we do not attempt to do so.

The divergence between national law and practice in other states is shown by our map of marijuana legality.

How much marijuana is allowed in the USA?

Federally there is no quantity threshold for possession. Section 844 punishes possession of a controlled substance as such, without reference to weight or number of plants, and the only distinction it makes concerns the prior criminal record of the offender, not the quantity. The offender’s history replaces the weight measure here.

This is a rare construction in this context. Most of the states we describe build liability around numbers: grams, plants, or active substance content. The federal regulation does not refer to any quantity table.

The scale of liability therefore increases with the offender’s history, not with the contents of their pockets. The first, second, and third offenses have separate ranges, and the limit is determined by valid convictions, not weight.

It is worth noting that state convictions also count. The law mentions prior convictions under this same law or for any drug offense under the law of any state, so both paths accumulate.

The lack of a threshold is neither a gap nor an oversight. It results from the construction of the regulation, which describes the act by mere possession of a substance from the schedule, not by its quantity.

What are the consequences of exceeding the threshold in the USA?

The ranges increase with each prior case, and this is their main principle. For the first simple possession, the penalty is up to one year of imprisonment and a fine of at least 1000 dollars, or both penalties at once, as determined by the federal court. The case is then handled by the federal prosecutor.

After one valid prior conviction under this law or for any drug offense under the law of any state, the ranges shift upwards: from fifteen days to two years and a fine of at least 2500 dollars.

After two or more such convictions, it is even higher: from ninety days to three years and a fine of at least 5000 dollars. Here, a lower limit of imprisonment appears, which is absent for the first offense.

It is worth noting something that is easy to overlook when reading the ranges. The lower limit of the fine is set by the law itself, so even the lightest form of the act does not allow the court to impose less.

These numbers describe only the federal path. What happens in practice depends on whether the case is handled by a federal or state authority, and the regulation does not resolve this itself.

Is there a medical marijuana program in the USA?

In April 2026, less changed than the headlines suggested, and three things that confuse each other need to be separated. On April 28, 2026, a final rule came into effect transferring FDA-approved marijuana-containing medicinal products from Schedule I to Schedule III.

The scope of this rule is narrow and conditional. It includes marijuana as defined by the law, extracts from marijuana, and delta-9-THC and other compounds derived from the plant outside of mature stalks and seeds, as long as they do not fall within the definition of hemp.

Additionally, there is the most important condition. The transfer only works to the extent that the substances enter an FDA-approved product or are covered by a state medical marijuana license. Outside of this scope, nothing has changed.

Marijuana itself remains in Schedule I. The entry described by number 7360 still stands there, and the new entries in Schedule III do not even have assigned code numbers yet, which clearly shows how early this change is.

A broader transfer, announced since May 2024, did not take place. On the same day, the agency withdrew the notice of the hearing and ended the ongoing proceedings, then initiated a new one, publishing the notice in the same issue of the official journal. The matter is therefore ongoing, not closed.

Frequently asked questions

Is marijuana legal in the USA?

Federally no. It is listed in Schedule I of the Controlled Substances Act, alongside LSD, mescaline, and peyote, and Schedule I means no recognized medical use. State law is separate, and this entry does not describe it.

How much marijuana can be possessed in the USA according to federal law?

The regulation does not provide a threshold. Section 844 punishes possession of a controlled substance as such, without reference to weight or number of plants. The only distinction concerns the prior criminal record of the offender.

What are the penalties for first marijuana possession federally?

Up to one year of imprisonment and a fine of at least 1000 dollars, or both penalties at once. The lower limit of the fine is statutorily mandatory, not discretionary.

Was marijuana moved to Schedule III in 2026?

Only FDA-approved medicinal products containing marijuana. Marijuana itself remains in Schedule I, and the broader transfer announced since May 2024 did not take place.

Does a legal state protect against federal liability?

The federal schedule knows no territorial exceptions and does not refer to state legislation. A state license does not change the federal status of the goods; it only operates in a separate legal order.

Does a prior state conviction increase federal penalties?

Yes. The law mentions prior convictions under this same law or for any drug offense under the law of any state, so both paths count together.
