Is It Illegal to Mail Weed?

Yes, mailing weed is illegal. In the United States, it is illegal to mail any controlled substance without express permission from a licensed practitioner or another authorized federal agency. This is outlined in Title 21 of the Controlled Substances Act, which restricts the transport of drugs via mail and other commercial services. Additionally, if you are caught mailing weed, you can face serious legal consequences, including heavy fines and possible jail time.

The Federal Law on Mailing Weed

Under federal law, marijuana is classified as a Schedule I controlled substance, making it illegal to grow, sell, or possess it. This classification applies to mailing weed as well, and it is illegal to use the United States Postal Service (USPS) or any other federal carrier to transport marijuana.

The Controlled Substances Act (CSA) makes it illegal to manufacture, distribute, or possess marijuana, even for medical use in states where it is legal. This law applies to all states and territories, regardless of state laws regarding marijuana. Violating the CSA can result in severe penalties, including fines, imprisonment, and forfeiture of property.

State Laws on Mailing Weed

While marijuana is illegal under federal law, some states have legalized it for medical or recreational use. As a result, the legality of mailing weed can vary depending on the state you are in and the laws that apply. In states where marijuana is legal, it may be possible to mail weed within the state, but it is still illegal to use the USPS or other federal carriers.

In states where marijuana is still illegal, mailing weed is also illegal and can result in serious consequences. It is important to be aware of the specific laws in your state and to understand the potential consequences of mailing weed.

The Risks of Mailing Weed

Aside from the legal consequences, there are also significant risks involved in mailing weed. For one, it is illegal to use the USPS or other federal carriers to transport marijuana, regardless of state laws. Doing so can result in the seizure of the package, fines, and even imprisonment.

Mailing weed also poses a risk to the safety and security of the postal system, as well as to the privacy of individuals. There have been numerous cases of packages containing marijuana being intercepted by law enforcement and individuals being charged with drug trafficking. Additionally, the odor of marijuana can often attract attention, making it easier for law enforcement to detect and seize packages containing weed.

Does USPS check pages for drugs?

There is some speculation as to whether or not the USPS checks packages for drugs. While there have been cases where the postal service has reportedly intercepted drug shipments in the past, it is unclear if they actively search all mail for illegal substances. However, it is important to keep in mind that even if your package is not searched by the post office, it is still possible for law enforcement or someone else to open your mail and discover the contents, which could have serious consequences for you.

I’ve heard stories from relatives on how they’ve shipped many packages and never have been caught but like I have said before: do not attempt this. It isn’t worth getting caught and having your life messed up for a bit.

What About UPS and FedEx?

In addition to the US Postal Service (USPS), there are several other postal services that may be used to mail packages, including private carriers like FedEx, UPS, and DHL. These private carriers are subject to federal law, and it is illegal to use them to transport marijuana, regardless of state laws.

While these carriers may not actively seek out packages containing marijuana, they do have policies in place to address the issue if they become aware of it. For example, FedEx has stated that it will not knowingly transport marijuana and will cooperate with law enforcement to address any violations of the law. UPS and DHL have similar policies in place and also cooperate with law enforcement to address any violations.

It’s important to note that these carriers also have the right to inspect packages for any reason and may open packages if they suspect illegal activity, including the transportation of marijuana. If a package containing marijuana is discovered, the carrier may seize the package and turn it over to law enforcement, which could result in serious legal consequences for the sender and recipient.

In summary, while private carriers may offer more privacy than the USPS, they are still subject to federal law and their policies prohibit the transportation of marijuana. Using private carriers to mail weed still poses significant risks and could result in serious legal consequences.

What About Mailing A Weed Pen?

Some people also wonder if it is legal to mail something like a weed pen, or other kinds of cannabis products that may not necessarily contain THC.

At this point, the legality of mailing cannabis products is unclear and varies from state to state. However, regardless of the laws in your area, you should always be cautious when shipping any kind of controlled substance, as you could face serious legal consequences even if the product is meant for medical or recreational use.


If you are thinking about mailing weed, it is important to be aware of the risks and legal consequences involved. While there is still a lot of uncertainty around this issue, it is best to err on the side of caution and avoid sending any kind of controlled substance via mail, regardless of where you live. Instead, you may want to consider other legal and safer options for obtaining, purchasing, and using marijuana products.
