Marijuana legalization has become a hot topic among politicians, users, and those who believe in the drug’s potential for health effects. While some states have legalized recreational cannabis, others have only legalized medical marijuana. Some other states have marijuana laws that have completely banned the plant altogether.
The Controlled Substances Act of 1970 made marijuana a Schedule One substance. So, it is important to note that at the time of the publication of this article, the use of cannabis is still federally illegal.
The substance in marijuana that gets users high, tetrahydrocannabinol, is commonly known as THC. This psychoactive substance is the primary cannabinoid in the cannabis plant. Here, we are going to break down the legal status of marijuana use per state, including the following:
- Home Cultivation
- Recreational Purposes
- Accepted Medical Use
- States That Have Decriminalized Cannabis
- Legal Cannabis Trade
Understanding Marijuana Legalization

As it stands, the legal status of THC in the US varies by state and federal laws, with hemp being treated differently than marijuana.
Hemp vs. marijuana
Cannabis is a plant that can be broken down into two distinct varieties: hemp and marijuana. Generally speaking, the legal classifications of these plants are based on their THC content.
Hemp-derived products generally contain 0.3% or less THC by dry weight; anything with higher levels than this falls under the classification of marijuana, as per federal law. The 2018 Farm Bill legalized the regulated production of hemp for commercial use in agriculture and other industries such as bioplastics, medicine manufacturing, foodstuffs, textiles and even construction materials.
In contrast to hemp’s legal status, marijuana remains illegal federally due to its higher THC levels, which give it psychoactive properties. However, some states have developed legislation to allow for medical or recreational use depending on local regulations in those particular states.

State laws and discrepancies
Federal and state laws regarding the legality of THC in the US often conflict and cause confusion. The following summarizes some of these discrepancies regarding state laws on THC:
California: Here, medical marijuana and recreational cannabis are legal, but this contradicts federal law.
Colorado: Medical marijuana and recreational cannabis are legal, but this contradicts federal law.
Idaho: THC is considered an illegal drug.
New York: Medical cannabis and recreational marijuana are both legal, contradicting federal law.
Texas: Marijuana is legal for medical use, but the state has yet to legalize recreational marijuana.
The conflict between state and federal cannabis laws creates a complex legal landscape. This leads to challenges for businesses in the marijuana industry, as each state has its own set of laws and regulations regarding the use and distribution of marijuana. The evolving legal status under federal and state laws can lead to conflicts and confusion.
Federal laws and regulations
The federal government has two main laws in the U.S. that control and regulate THC: the Controlled Substance Act and federal law enforcement policies put forward by Attorney General Jeff Sessions in 2017.
Under the 1970 Controlled Substance Act, cannabis is classified as a Schedule I substance – meaning it’s considered subject to restrictions for medical and recreational use, similar to drugs like heroin or LSD.
This means that under federal law, any form of possession or use of marijuana containing THC, including medically prescribed forms such as edibles or oils, is illegal in the United States unless otherwise specified by state legislation.
This classification can also have more widespread implications than mere criminal charges – individuals caught with marijuana may find themselves ineligible for certain benefits or job opportunities due to employment restrictions set forth under this act; they might even find themselves unable to purchase firearms due to gun ownership regulations related to drug classification systems established within the act itself.
Medical vs. Recreational Use of THC

The legal status of THC for medical and recreational use varies significantly from state to state, with only a few states having fully legalized its use.

Medical benefits and regulations
THC, the active component of cannabis, is known to offer many potential medical benefits. Studies have revealed its ability to alleviate pain and inflammation for those with certain chronic conditions.
Thirty-eight states plus Washington D.C. have legalized the use of medical marijuana as a way to treat certain qualifying medical conditions such as cancer, epilepsy, HIV/AIDS, post-traumatic stress disorder (PTSD), glaucoma, and multiple sclerosis (MS).
States that allow for the use of medical cannabis typically require patients to obtain a valid authorization from a physician and register with their state’s health department to be eligible for treatment under their law.
Navigating Legality Of Marijuana

The legal status of THC in the United States is a complex and divisive issue. While eight states have legalized recreational use, many more allow medical marijuana. At the federal level, THC continues to be classified as an illegal Schedule I substance with no approved medical uses; still, a growing number of research studies may soon change that designation.
In this ongoing debate over legalization, each side makes compelling arguments based on public health concerns and current scientific evidence. Ultimately, education and responsible regulation are critical to making informed decisions about the safety, efficacy, and potential risks associated with cannabis use.
