Is marijuana addictive?

Given the legalization of marijuana, many have wondered about the substance, its safety, and whether it’s addictive. Marijuana – also known as weed, marijuana and other names – is a plant used as a medicinal and recreational drug.

People can become addicted to marijuana. While it is possible to try the substance without becoming addicted, not everyone does. There are risks to use, even for medicinal purposes, and addiction is one of them.

As with any medicinal drug, the potential risks and potential benefits of use are weighed when deciding what to try and what not to try. Learn more about marijuana addiction, risk factors, effects on the brain and more.

Is marijuana addictive?

While some people can try cannabis without becoming addicted, it can also be addictive to some. Marijuana use disorder, also known as marijuana use disorder, is when marijuana use has a negative impact on a person’s health or life, yet they continue to use it.

While the numbers aren’t entirely clear, it’s estimated that 6.3 percent of adults have marijuana use disorder, and that number is increasing. As many as 30% of people who use marijuana may develop marijuana use disorder. Cannabis use can also be associated with addiction and dependence.

Addiction and Dependence

Addiction and dependence are two terms that are often used interchangeably. There is a difference between the two.

Addiction occurs when a person overuses substances such as alcohol, marijuana, or other drugs. It is often marked by behavioral changes that keep people focused on using the substance regardless of potential negative outcomes. Addiction can be physical, psychological, or both.

Substance dependence, also known as chemical dependence, is when a person has a physical dependence on a substance, but is not addicted. An example is when someone who has been taking a prescription drug for a long time stops taking the drug and experiences physical or mental withdrawal symptoms. Dependence symptoms can be cognitive, behavioral, and physical.

Dependency manifests as a pattern. A person starts by repeatedly using substances such as marijuana. With regular use over time, they develop tolerance, in which case the effects of the substance go unnoticed or go unnoticed at all. The person develops symptoms when they stop using the substance, which makes them feel the need to use the substance again.
