Are Coca Leaves Illegal in the United States?

Yes, coca leaves are illegal in the United States for almost everyone. Federal law classifies them as a Schedule II controlled substance, which means possessing, importing, growing, or distributing them without specific federal authorization is a crime. Narrow exceptions exist for decocainized extract used as a food flavoring, DEA-registered scientific research, and authorized pharmaceutical processing, but none of those pathways are open to ordinary consumers, travelers, or gardeners.

Schedule II Status and What It Means

Under 21 U.S.C. § 812, coca leaves sit on Schedule II of the Controlled Substances Act, alongside cocaine, fentanyl, and oxycodone.¹ Schedule II substances are treated as having a high potential for abuse and a risk of severe dependence, tempered by some recognized medical use. The DEA’s own regulations mirror this and add one specific carve-out: decocainized coca leaves and extracts, meaning material from which cocaine and ecgonine have been removed, are excluded from Schedule II entirely.²

That distinction is important because it explains why some products containing “coca” are legal while the leaves themselves are not. Whole coca leaves contain cocaine and related alkaloids. Once those alkaloids are stripped out through industrial processing, the remaining flavor extract is no longer a controlled substance and is permitted as a food additive under 21 CFR 182.20.³ For a private person, that carve-out is not a useful loophole. You cannot do the extraction at home, and you cannot buy raw leaves and process them yourself.

Bringing Coca Leaves or Coca Tea Back from South America

This is where travelers get into trouble. Coca tea, often sold as mate de coca, is legal and common in Peru, Bolivia, and Colombia. Buying a box at a market in Cusco is unremarkable. Packing it in your suitcase for the flight home is not.

Federal law prohibits importing coca leaves into the United States. Under 21 U.S.C. § 952, importing any Schedule II substance is generally barred, with a limited exception allowing the Attorney General to authorize importation for medical, scientific, or other legitimate purposes.⁴ That exception exists to let a single authorized industrial importer operate; it does not cover individuals.

Customs and Border Protection is explicit on this point: it is illegal to bring coca leaves into the United States for any purpose, including brewing tea or chewing.⁵ CBP treats an attempt to walk coca leaves through a checkpoint as smuggling. The leaves will be seized. Depending on quantity and circumstances, criminal charges can follow. Telling the officer the tea was for personal use is not a defense; the statute does not distinguish between leaves destined for tea and leaves destined for anything else.

Decocainized coca tea products do exist and are legal, but CBP notes they are generally not sold in South American countries and must be sourced from authorized U.S. importers.⁵ If a tea bag you bought abroad is labeled “coca,” treat it as illegal to bring in.

Federal Penalties

Penalties depend heavily on what you were doing with the leaves and how much you had. The gap between a few tea bags and bulk quantities is the gap between a misdemeanor and decades in federal prison.

Simple Possession

A first offense of simple possession, with no intent to distribute, carries up to one year in prison and a minimum $1,000 fine. A second offense after a prior drug conviction runs from 15 days to two years and at least $2,500. A third or later offense carries 90 days to three years and a minimum $5,000.⁶

Distribution and Trafficking

Distributing coca leaves, or possessing them with intent to distribute, falls under 21 U.S.C. § 841. The quantity thresholds count the total weight of the mixture, not pure alkaloid content:

500 grams or more triggers a mandatory minimum of 5 years, up to 40 years. If someone dies or suffers serious bodily injury from the substance, the floor rises to 20 years and the ceiling becomes life. Individual fines can reach $5 million.
5 kilograms or more triggers a mandatory minimum of 10 years, up to life. Death or serious bodily injury raises the floor to 20 years. Individual fines can reach $10 million.

Prior convictions for serious drug felonies or violent felonies push both the minimums and the fine ceilings higher.⁷

Illegal Importation

Importation charges under 21 U.S.C. § 960 track the domestic trafficking penalties closely. The same thresholds apply: 500 grams or more brings 5 to 40 years, and 5 kilograms or more brings 10 years to life.⁸ For smaller quantities that fall below the mandatory minimum thresholds, importation still carries up to 20 years in federal prison.⁹

Mandatory minimums mean exactly that. A federal judge cannot sentence below the statutory floor, even in sympathetic circumstances.

The Narrow Legal Pathways

A handful of legal uses exist. None are available to ordinary people without going through the federal government first.

Decocainized Extract and Coca-Cola

The Stepan Company, based in New Jersey, is the only commercial entity authorized by the DEA to import coca leaves into the United States for processing. Stepan extracts the cocaine alkaloids under DEA supervision and produces the decocainized flavoring that goes to Coca-Cola. Federal Register notices confirm Stepan’s ongoing DEA registration as an importer of controlled substances.¹⁰ Under 21 U.S.C. § 952(c), all cocaine and ecgonine extracted from any leaves imported beyond strict medical or scientific needs must be destroyed under the supervision of an authorized representative.⁴

Research

Researchers who need coca leaves for legitimate studies must register with the DEA and submit a detailed research protocol covering the substance, quantities, and security measures, including storage in a securely locked, substantially constructed cabinet. Clinical investigations also require an Investigational New Drug exemption from the FDA before DEA registration can proceed.¹¹

Religious Use

Coca leaves play a central role in indigenous Andean spiritual practice, which raises the question of a religious exemption. In theory, one is possible. The Religious Freedom Restoration Act bars the federal government from substantially burdening religious exercise unless the burden serves a compelling interest through the least restrictive means.¹² In Gonzales v. O Centro Espírita Beneficente União do Vegetal (2006), the Supreme Court applied that standard to the Controlled Substances Act and allowed a church’s sacramental use of a DMT-containing tea, rejecting the argument that uniform CSA enforcement was itself a compelling interest.¹³

In practice, no publicly reported petition for coca leaf use has been granted. The DEA’s guidance requires a written petition detailing the religion’s history, the specific practices, the amounts needed, and the conditions of use, and no CSA-prohibited activity is permitted until the petition is formally granted and a DEA registration issued.¹⁴ Until that happens, use is illegal.

Coca Seeds and Growing the Plant

The statute lists “coca leaves” as the Schedule II substance and does not separately name coca seeds or other parts of the Erythroxylum coca plant.¹ That gap in the text is less helpful than it looks. Growing a coca plant produces coca leaves, which are controlled, and cultivating the plant with knowledge that it will produce a controlled substance can support a federal manufacturing or possession charge. The DEA has treated coca cultivation as illegal, and courts have not accepted the argument that seeds alone escape the statute. Growing coca in the United States without DEA authorization is treated the same as possessing the leaves themselves.
