Adolescents, Cannabis and Psychosis


As we move towards widespread legalization, there is a need to understand whether cannabis use has a role in developing psychiatric illness.

The following study proves that there is.

Almost 4,000 kids, ages 13 to 16 years old, self-reported via an online survey, their frequency of cannabis use and their experience of psychosis symptoms following its use. Psychosis is an abnormal condition of the mind that results in difficulty in determining between what is real and what is not. Symptoms may include false beliefs which include seeing or hearing things that are not there. Other symptoms may include incoherent speech, behaviors that are inappropriate for the situation, sleep problems, social withdrawal, lack of motivation, and difficulty carrying out daily activities.

The study statistically reported significant and positive associations between use of cannabis and experiencing psychosis symptoms up to one year after use. All young users face the risk of psychosis, not just those with a family history or biological factor that increased their susceptibility to the effects of cannabis.

Young users, ages 13 to 16 years old, have not yet reached the age for full brain development, which occurs anywhere between 24 and 26 years of age. Cannabis use prior to reaching 24 to 26 years of age averts the brain from fully developing.

The bottom line is that permanent brain damage usually occurs from cannabis usage in adolescents. It may also stop brain development, which continues until an individual reaches 24 to 26 years old.

It’s also possible that cannabis damages the brain in anyone who uses it, regardless of age. Cannabis could also cause psychosis or cause destruction or deterioration of brain cells.
