- Marijuana is the most commonly used federally illegal drug in the United States, with approximately 61.9 million Americans reporting use in 2022.
- Cannabis use disorder affects approximately 3 in 10 marijuana users, with risk increasing significantly for those who begin before age 18.
- Modern marijuana is dramatically more potent than decades past, with average THC content increasing from approximately 4% in 1995 to over 15% in 2023, and concentrates exceeding 80%.
- Marijuana withdrawal syndrome is now recognized in the DSM-5, with symptoms including irritability, insomnia, decreased appetite, and anxiety.
- Adolescent marijuana use is associated with lasting impacts on brain development, IQ reduction, and increased risk of psychotic disorders.
- Treatment for marijuana addiction relies on behavioral therapies, as no FDA-approved medications exist specifically for cannabis use disorder.
What Is Marijuana?
Marijuana refers to the dried flowers, leaves, stems, and seeds of the Cannabis sativa or Cannabis indica plant. The primary psychoactive compound is delta-9-tetrahydrocannabinol (THC), which acts on cannabinoid receptors throughout the brain and body.
Forms of Marijuana
- Flower/bud: Traditional dried plant material (15-25% THC)
- Edibles: THC-infused foods and beverages
- Concentrates: Wax, shatter, oil, dabs (60-90% THC)
- Vape cartridges: THC oil for vaporization
- Tinctures: Liquid THC extracts
- Topicals: THC-infused creams and lotions
The Potency Problem
Today's marijuana is fundamentally different from the drug used in previous decades: - 1970s average THC: approximately 1-3% - 1990s average THC: approximately 4% - 2020s average THC: 15-25% (flower), 60-90% (concentrates)
This dramatic increase in potency has amplified both the addiction potential and the health risks associated with marijuana use.
Can You Really Get Addicted to Marijuana?
Yes. Despite widespread perception that marijuana is non-addictive, scientific evidence clearly demonstrates that cannabis use disorder is a real clinical condition:
- Approximately 9% of all marijuana users develop cannabis use disorder
- 17% of those who begin using in adolescence develop it
- 25-50% of daily users develop it
- An estimated 6.3 million Americans meet criteria for cannabis use disorder
DSM-5 Criteria for Cannabis Use Disorder
Cannabis use disorder is diagnosed when marijuana use causes clinically significant impairment, meeting two or more criteria including: - Using more or longer than intended - Unsuccessful attempts to quit - Spending excessive time obtaining, using, or recovering - Cravings - Failure to fulfill major role obligations - Continued use despite social problems - Giving up important activities - Use in physically hazardous situations - Continued use despite physical or psychological problems - Tolerance - Withdrawal

FAQ
Is marijuana really addictive?
Yes. Approximately 3 in 10 marijuana users develop cannabis use disorder. The risk increases with earlier age of onset, higher potency products, and more frequent use.
Is marijuana a gateway drug?
The "gateway" concept is debated. Marijuana use is associated with increased likelihood of using other substances, but the relationship is likely due to shared risk factors (genetics, environment, mental health) rather than marijuana directly causing progression to harder drugs.
Is medical marijuana addictive?
Medical marijuana contains the same THC as recreational marijuana and carries the same addiction potential. Patients using medical marijuana should be monitored for signs of misuse and escalation.
How do I know if I need treatment for marijuana?
If marijuana use is causing problems in your relationships, work, school, health, or finances, and you have been unable to stop or reduce on your own, professional treatment can help.
