Misconceptions about Marijuana: Understanding the Addiction Potential

Marijuana Addiction

In recent years, marijuana has gained more social acceptance as states legalize its use. As of this post’s publication, over 30 states and the District of Columbia have legalized marijuana in some form, and more than 10 states have fully legalized marijuana for recreational use.

Great news, right? It is…but there’s a caveat. Unfortunately, a common misconception about marijuana still exists:
“Marijuana is not addictive or harmful.”

The sad truth is—Yes, marijuana can be addictive. Is it always? No, of course not. People can develop a dependency on it, however…a dependency that interferes with their health, finances, and relationships.

This misconception particularly affects, and has long-term implications for, teens and young adults. According to the National Center for Drug Abuse Statistics, almost 40% of high school students have tried marijuana!

More young people think marijuana is risk-free than ever before. While marijuana has shown some good medical benefits for many people (e.g. cancer patients), it is a type of drug when smoked or consumed. Any such drug can have problematic effects, both short- and long-term.

Negative Effects of Marijuana

Short-term effects on the brain include heightened mood, changes in mood, altered senses, impaired body movement, issues with problem-solving, and impaired memory. In high doses, marijuana can cause hallucinations, delusions, and even psychosis (in rare cases).

Physical short-term effects include an increased heart rate for up to three hours after using it, which increases the chance of heart attack.

The long-term effects of marijuana can become quite serious, especially for those who start using it young. For example, the drug actually affects brain development over time. According to NIDA,

“When people begin using marijuana as teenagers, the drug may impair thinking, memory, and learning functions and affect how the brain builds connections between the areas necessary for these functions. Researchers are still studying how long marijuana’s effects last and whether some changes may be permanent.”

-National Institute on Drug Abuse

Long-term marijuana users lose mental abilities. Abilities that don’t completely return if the person quits using marijuana as an adult. It’s no surprise regular marijuana users often show poor academic performance.

Worse, using marijuana long-term has been linked to mental health issues, including depression, temporary paranoia, and exacerbation of pre-existing mental illness such as schizophrenia.

Physical long-term effects include breathing problems similar to those cigarette smokers experience: a daily cough, higher incidence of lung infections, and more frequent lung illnesses.

But is marijuana actually addictive?

Yes, it can be, in one sense. Frequent use of marijuana may lead to a person developing a mental dependence on it, to the point where it causes problems in multiple areas of their life. This is called a “Marijuana Use Disorder.” Those who start using marijuana before age 18 are 4-7 times more likely than adults to develop marijuana use disorder.

This disorder is not as serious as a physical dependence, in the case of alcohol or heroin. But it is a form of addiction, and needs to be treated as such.

People suffering from Marijuana Use Disorder report mild withdrawal symptoms when trying to quit, such as problems sleeping, decreased appetite, grouchiness, anxiety, and cravings.

I’m trying to quit, but can’t. What should I do?

Behavioral interventions and support for marijuana addiction have shown effectiveness. There are support groups for those who think they may have a problem with marijuana too. Drug treatment programs generally treat marijuana use disorder, including residential, day and outpatient programs.
