What Does the Federal Law Say About Cannabis Delivery Services?

Even though cannabis is legal in California and many other states, it is still a banned controlled substance under federal law. Due to the complex status of recreational and medical marijuana in the United States, there may be serious repercussions for mailing pot outside of The Golden State.

Under the federal Controlled Substances Act (CSA), most marijuana, including adult-use (recreational) marijuana, is still classified as a Schedule I controlled substance. Schedule I means the federal government considers the drug to have a high potential for abuse and no currently accepted medical use. In April 2026, the DEA moved FDA-approved marijuana products and marijuana covered by a qualifying state medical marijuana license to Schedule III, and a broader rescheduling proposal is still pending. Neither change makes it legal to mail marijuana.

Federal law takes precedence when it comes to the country's mail delivery services, such as the United States Postal Service, which can lead to serious ramifications for the sender.

What Does the State Law Say About Cannabis Delivery Services?

While the federal government may have banned the use and shipment of illegal drugs, including marijuana, states have implemented their own rules regarding the legality of cannabis.

In California, licensed retailers may deliver cannabis to customers using their own employees and vehicles. This is licensed retailer delivery, not mailing, and it began with state licensing in 2018. The law also allows businesses to operate delivery-only cannabis services as long as the company has the right licenses.

Mailing weed outside of California can lead to trouble. Even in states where the medicinal and recreational use of marijuana is legal, the country's delivery companies may follow federal jurisdiction instead of state laws.

Is It Legal to Send Cannabis in the Mail in California?

No. Mailing marijuana is illegal, even within California. What California allows is delivery by a licensed retailer, using its own employees and vehicles, to customers in the state.

For residents, the rules depend on what they are doing. Adults 21 and older may give away up to 28.5 grams of cannabis to other adults, as long as they receive nothing in return. Selling or delivering cannabis for payment without a license is illegal. Shipping cannabis to or from another state is illegal, and transporting or importing more than 28.5 grams into or out of California for sale can be a state felony.

Is It Possible to Send Cannabis in the Mail in California?

While it's possible to mail illegal substances inside and outside of California, and many people do it, that doesn't mean that it's legal. The act could lead to serious consequences, including jail time and hefty fines if caught.

United States Postal Service (USPS)

Sending legalized cannabis through the United States Postal Service (USPS) can be risky. Since the company follows federal law, there is a high chance that it may intercept the package and pursue criminal action against the sender.

Mailing cannabis by any carrier is illegal. Under federal law, distributing even a small amount of marijuana can carry up to five years in federal prison, and using the mail to commit a drug offense can be charged as a separate crime carrying up to four more years.

Third-party Delivery Services

There are many other delivery companies in California that are not federal agencies. Shipping cannabis through them is also illegal.

Another thing that could be a serious concern is the willingness of these delivery companies to cooperate with federal agencies in cracking down on illegal drug trafficking.

After a couple of out-of-court settlements, including the $40 million paid by UPS to settle a federal probe in 2013, logistics businesses have increased their due diligence to monitor packages for illegal drugs to avoid such cases.

What Are the Consequences of Mailing Federally Illegal Substances Like Marijuana in California?

There are several legal risks of mailing weed in and outside of California, some of which include the following:

• Mailing marijuana is a federal offense, and depending on the state, the sender may have to face criminal charges under both federal and state law.
• It could also lead to interstate trafficking, which can increase the severity of the charges.
• Federal agencies may offer cash prizes to USPS and private company employees who provide information on the sender and receiver of the package. This could be enough to make an arrest, leading to a conviction.

The delivery of illegal controlled substances is a felony, and it could result in up to five years of imprisonment or more, depending on the facts surrounding the criminal case.
