What You Need to Know about Federal and State Laws

Cannabis legalization in the United States is a complex matter. With the state and federal governments having separate laws governing the use, possession, and distribution of marijuana, it's like navigating a sea of green while battling the winds of contradictory laws. To fully grasp the situation, it's crucial to understand the specifics of these federal and state laws.

Let's begin by laying down the foundation, the Controlled Substances Act (CSA). Enacted in 1970, this federal drug policy under Title II of the Comprehensive Drug Abuse Prevention and Control Act categorizes substances into five schedules based on their potential for abuse, current accepted medical use, and the degree of dependency the substance may cause.

Marijuana falls under Schedule I, the most restrictive category. According to the U.S. Code Title 21 Section 812, Schedule I substances have a high potential for abuse, no currently accepted medical use in treatment in the United States, and a lack of accepted safety for use under medical supervision.

The dichotomy between state and federal laws comes into play because the federal government, under the Supremacy Clause of the Constitution, has the power to preempt state laws. This means that if a state law conflicts with a federal law, the federal law, in theory, takes precedence. As of my knowledge cutoff in September 2021, this contradiction hasn't been tested in the Supreme Court in the context of marijuana laws.

Now, where does mailing marijuana fit into all this? Mailing marijuana is considered a federal offense under several sections of the U.S. Code. Specifically, under U.S. Code Title 21 Section 841, it's unlawful to manufacture, distribute, or dispense, or possess with intent to manufacture, distribute, or dispense, a controlled substance. Given that marijuana is classified as a Schedule I substance, it's included under this law.

Additionally, under U.S. Code Title 18 Section 1716, it's illegal to mail items that can cause harm, including poisons and explosives. As marijuana is considered a controlled substance under federal law, it's included in this category. Violation of this statute can lead to fines, imprisonment, or both.

Meanwhile, state laws concerning marijuana vary significantly. Many states, such as California, Colorado, and Massachusetts, have legalized both recreational and medical marijuana. Other states, like Texas and South Carolina, have more restrictive laws. These laws permit only specific, limited use of medical marijuana and have harsh penalties for possession, use, or distribution beyond these allowances.

While some states have implemented systems for the legal delivery of marijuana within the state, they're bound by the state lines. Crossing state lines while carrying marijuana is considered a federal offense under the Controlled Substances Act, regardless of the legality of marijuana in the respective states.

Navigating the green waters of marijuana legality can be incredibly complex due to these intricate and often conflicting laws. The key is to stay informed about the specific laws in your state and the federal laws governing marijuana. As the legal landscape continues to evolve, there's hope for more clarity and less contradiction in the future.

The U.S. Postal Service are no Pushovers

The United States Postal Service (USPS), a federal agency, operates under the laws of the land - meaning, federal laws. Despite being a common carrier, USPS cannot legally transport marijuana or marijuana products. But, here's a fun fact for you: USPS requires a search warrant to open any suspicious package. And, acquiring this warrant requires probable cause, an aspect protected under the Fourth Amendment.

Now, let's get into some specifics. Postal inspectors, the law enforcement arm of the USPS, are federal law enforcement agents who have the power to enforce the Controlled Substances Act. They use advanced drug detection systems such as drug-sniffing dogs and X-ray scanners to identify illegal substances in the mail. If a postal worker identifies a suspicious package, which could be due to odd smells, leakage, or even if it's excessively wrapped in plastic bags, they're trained to set it aside for further investigation.

Even if you were to cleverly conceal your cannabis products within hemp products, the postal workers are trained to sniff out such trickeries. Hemp-derived products, including hemp-derived CBD, are legal under the Farm Bill, as long as their THC content is 0.3 percent or less. But, despite hemp products being legal to mail, if your package gives any reason to suspect the presence of an illegal drug, it may find itself under the microscope of a postal inspector.

What about Private Couriers?

One might think private couriers like FedEx or UPS are the safest way to send cannabis across state lines. However, these large private carriers have their own policies and guidelines in place. While they operate independently from the federal government, they're still required to comply with all federal guidelines when it comes to shipping illegal substances.

The bottom line is, it's still considered illegal to mail marijuana through third-party carriers. Shipping services like UPS and FedEx reserve the right to open and inspect packages at their own discretion.

The Penalties: A Serious Crime

Now, let's dive deeper into the ocean of penalties that accompany the crime of mailing marijuana. As you can guess, this ocean is neither pleasant nor forgiving. It's an expanse filled with treacherous waves of federal charges and the ominous undercurrents of potential jail time.

In the eyes of federal agencies, especially the Drug Enforcement Agency, the act of mailing marijuana is more than just an illegal drug transaction. It's classified as drug trafficking, a more serious crime that's a notch above mere possession.

If caught mailing marijuana, you may not only face state-level penalties but also federal charges. On a federal level, the penalties for trafficking marijuana vary significantly, largely depending on the amount of marijuana involved in the transaction.

For instance, if you're caught mailing less than 50 kilograms, or approximately 110 pounds of marijuana, you could face up to five years in federal prison and fines up to $250,000 for a first offense. For a second offense, the potential prison time doubles up to 10 years, and fines can soar up to $500,000.

If you're busted mailing more substantial amounts, say between 100 to 999 kilograms, the penalties escalate drastically. A first offense could land you in a federal penitentiary for 5 to 40 years, along with fines that can go up to $5 million. Repeat offenders, buckle up because the punishment is a minimum mandatory sentence of 10 years to life and fines that can reach a staggering $8 million.

Perhaps you think these scenarios are mere hypotheticals and that such penalties are reserved only for the biggest players in the illegal drug trade. If so, real-world examples might paint a clearer picture of the reality.

In 2016, a woman from Killeen, Texas, was sentenced to four years in federal prison for mailing between 50 and 100 kilograms of marijuana from California to Texas. In another instance, a man from North Carolina was sentenced to a decade behind bars in 2017 for his involvement in mailing upwards of 40 pounds of marijuana from California.

Then, there's the case of a Pennsylvania man who was handed a sentence of 15 years in prison for mailing quantities of marijuana exceeding 100 kilograms. And these are just a few instances. There are countless similar stories across the United States where individuals have faced significant prison time for attempting to mail marijuana.

What's more, penalties can increase if the federal court determines that the marijuana was sent to a minor or to a school zone, if firearms were involved, or if someone was seriously injured or killed as a result of the offense. Plus, penalties can also be higher for those who have prior criminal records, especially previous drug offenses.

These real-life examples are stark reminders of the high stakes involved in shipping weed, whether for personal use, to share with a friend, or for larger scale distribution. The U.S. Postal Service, private couriers, and other shipping services are no joke when it comes to cracking down on the illegal shipment of marijuana, and federal law enforcement does not take these offenses lightly.

What about mailing small amounts of marijuana?

Alright, let's shift gears and delve into what happens when smaller amounts of marijuana are involved in mailing. You might think that mailing just a gram or two couldn't possibly result in severe penalties. However, the reality is that mailing any amount of marijuana can have significant legal consequences.

Federal laws don't discriminate between amounts when it comes to the illegal distribution of controlled substances. Even if you're caught shipping a small package containing a few grams of weed, you're still breaking federal law.

There have been cases where individuals were penalized for mailing small amounts of marijuana. For instance, in 2018, a woman in Missouri was sentenced to two years in prison for mailing just 5 pounds of marijuana. Similarly, in 2019, a man in Oregon was sentenced to one year and a day in prison for mailing a small package containing 4.4 pounds of marijuana.

What about edibles, you ask? They're not off the hook either. Even marijuana-infused products, like cookies or brownies, fall under these same laws and penalties since they contain THC, the primary psychoactive compound in cannabis. If caught mailing such items, you could be subjected to similar penalties as those for mailing marijuana itself.

It's also worth noting that penalties can vary based on the individual's criminal history and any additional crimes associated with the mailing offense. For example, if a person with a previous drug conviction is caught mailing marijuana, the penalties could be more severe. Similarly, if the person was attempting to mail the marijuana to a minor or within a school zone, the consequences could also be more significant.

The bottom line? Mailing any amount of marijuana, regardless of how small, is a federal offense with potential jail time and hefty fines. It's a high-risk game, with the house (in this case, federal law enforcement) holding all the cards. The safest bet is to stay on the right side of the law.

The Silver Lining: Medical Marijuana Delivery

While the majority of the article has focused on the perils and penalties associated with mailing marijuana, let's shed some light on the positive aspect of cannabis distribution - the medical marijuana delivery system. The evolution of cannabis laws in the United States has led to significant changes in how medical marijuana patients can access their medicine.

Today, several states that have legalized medical marijuana also allow for state-licensed dispensaries to deliver these products directly to patients. However, it's critical to remember that these delivery services are bound by strict state regulations. These regulations often include stipulations such as drivers carrying a copy of the dispensary's current state license, the marijuana being locked in a box within the vehicle, and deliveries being made only within the state.

Now, this leads to an interesting question: could there be a possibility of national medical marijuana delivery in the future?

The laws surrounding interstate marijuana commerce remain quite stringent. Marijuana, despite its legal status for medical and even recreational use in many states, remains a Schedule I drug at the federal level. This classification creates a significant barrier for interstate marijuana commerce, including medical marijuana delivery.

However, with the continuous evolution of marijuana laws and the growing acceptance of its therapeutic potential, it's plausible that these barriers could eventually be dismantled. Federal legalization would be a game-changer, paving the way for regulated, nationwide medical marijuana delivery.

If this were to occur, it would revolutionize access to medical marijuana for patients across the country. No longer would patients be restricted by their geographic location or physical ability to travel to a dispensary. A world where medical marijuana can be legally delivered from one state to another could provide more people with the much-needed relief that this plant has to offer.

Of course, even with federal legalization, the establishment of a national medical marijuana delivery system would require a massive amount of regulation and oversight. It would need cooperation from various federal agencies, including the U.S. Postal Service, private couriers, and the Drug Enforcement Agency, to ensure that such a system couldn't be exploited for illegal marijuana distribution. Furthermore, guidelines would need to be in place to verify patients' medical marijuana recommendations and to prevent sales to minors.

While the idea of a national medical marijuana delivery system offers a lot of promise, it's still a hypothetical scenario as of now. The focus remains on advocating for further legislative changes and advancements in cannabis research. In the meantime, local delivery from state-licensed dispensaries offers a legal and safe way for medical marijuana patients to access their medicine.


As a member of the cannabis community, it's essential to respect the rules set forth by both local and federal entities. Mailing marijuana, tempting as it may be, falls under the realm of illegal activities and carries hefty penalties. In the real world, your best and only way to share the joys of cannabis is to do it locally, in person.
