I agree with you in that the patient would benefit from getting a job or going to school to occupy his time in productive way so that he is not tempted to smoke marijuana as much. Studies suggest that risk of marijuana addiction is now higher as cannabinoids, the psychoactive ingredient in marijuana, is four times stronger than marijuana found before the 21st century. Despite misinformation found on the internet, cannabis, is physically and mentally addictive and heavy cannabis use increases risk of anxiety, depression, and psychosis. Early onset of cannabis use is also associated with worsening cognitive function and a decline in IQ (Williams & Hill, 2019).
There are treatments that are available for individuals who are diagnosed with cannabis use disorder and are wanting to get help. There are various psychotherapies that can be employed including motivational enhancement therapy, cognitive behavioral therapy, and contingency management, which have shown effectiveness in reducing frequency and quantity of cannabis use. Longer duration of therapy is associated with improved outcomes and decrease risk of relapse. There are no FDA approved pharmacotherapies that are approved for the treatment of cannabis use disorder, however, there are new areas or research that may lead to new treatments (Brezing & Levin, 2017).
