4. About nine percent of adolescents who use marijuana become dependent upon it.
According to studies reported by the National Institute of Drug Abuse (NIDA), about nine percent of those who start using marijuana become dependent, compared to 17% who start using it in their teens. In addition, people who begin using marijuana before age 18 are four to seven times more likely to develop a marijuana use disorder than adults. Link: (Marijuana Addictive Report)
These data highlight the importance of avoiding marijuana use until later in life to reduce the potential for developing marijuana dependence and marijuana use disorders. Dependence can result in withdrawal symptoms like irritability, mood and sleep difficulties, decreased appetite, cravings, restlessness, and physical discomfort when not using, and can make quitting difficult. In addition, the steady increase in the amount of THC in marijuana over the past several decades, marijuana’s key active ingredient, might increase the likelihood for dependence, poisonings and other harmful effects, particularly among young and early users.
