SUBSTANCE USE DISORDERS

Some people who use marijuana will develop Cannabis Use Disorder (CUD), meaning that they are unable to stop using marijuana even though it’s causing health and social problems in their lives.

Some key statistics regarding

Cannabis Use Disorder (CUD)

-  4.8 Million Americans meet the criteria for Marijuana Use Disorder (includes people 12 or older)

-  Young people who use marijuana are 5-7 times more likely than adults to develop a drug problem.

-  9% of those who experiment with Marijuana will become addicted.

- 17% of teenagers who experiment with Marijuana become addicted.

-  25-50% of daily users become addicted.  

-  3 out of 10 Cannabis users develop a Cannabis Use Disorder.

-  Parents who use marijuana increase the likely hood that their children will use and misuse marijuana, tobacco and alcohol. 

-  Prevalence of cannabis use disorder (marijuana addiction) for youth age 12-17 was 10.7% if using less than one year or 20.1% if using more than 3 years.

 

-  Prevalence of cannabis use disorder, higher than alcohol use disorder in this age group. 

Addiction and Cannabis Use Disorder (CU)

Some people who use marijuana will develop marijuana use disorder, meaning that they are unable to stop using marijuana even though it’s causing health and social problems in their lives.

  • One study estimated that approximately 3 in 10 people who use marijuana have marijuana use disorder.1

  • Another study estimated that people who use cannabis have about a 10% likelihood of becoming addicted.2

  • The risk of developing marijuana use disorder is greater in people who start using marijuana during youth or adolescence and who use marijuana more frequently.3

The following are signs of marijuana use disorder 4:

  • Using more marijuana than intended

  • Trying but failing to quit using marijuana

  • Spending a lot of time using marijuana

  • Craving marijuana

  • Using marijuana even though it causes problems at home, school, or work

  • Continuing to use marijuana despite social or relationship problems.

  • Giving up important activities with friends and family in favor of using marijuana.

  • Using marijuana in high-risk situations, such as while driving a car.

  • Continuing to use marijuana despite physical or psychological problems.

  • Needing to use more marijuana to get the same high.

  • Experiencing withdrawal symptoms when stopping marijuana use.

 

People who have marijuana use disorder may also be at a higher risk of other negative consequences, such as problems with attention, memory, and learning.

Some people who have marijuana use disorder may need to use more and more marijuana or greater concentrations of marijuana over time to experience a “high.” The greater the amount of tetrahydrocannabinol (THC) in marijuana (in other words, the concentration or strength), the stronger the effects the marijuana may have on the brain.5,6  The amount of THC in marijuana has increased over the past few decades.6

In a study of cannabis research samples over time, the average delta-9 THC (the main form of THC in the cannabis plant) concentration almost doubled, from 9% in 2008 to 17% in 2017.7 Products from dispensaries often offer much higher concentrations than seen in this study. In a study of products available in online dispensaries in 3 states with legal non-medical adult marijuana use, the average THC concentration was 23%, with a range of 0% to 45%.8 In addition, some methods of using marijuana (for example, dabbing and vaping concentrates) may deliver very high levels of THC to the user.6,9 

 

Researchers do not yet know the full extent of the consequences when the body and brain are exposed to high concentrations of THC or how recent increases in concentrations affect the risk of someone developing marijuana use disorder.6
