Marijuana use in teenagers does not affect IQ
A study in the journal ‘'Journal of Psychopharmacology'’, A study conducted by British scientists suggests that moderate marijuana use in adolescents may have little cognitive impact and does not harm the brain. It also indicates that it is not a direct cause of poor academic performance.
Another scenario is when marijuana use ceases to be moderate and becomes abusive, developing into an addiction. In such cases, long-term effects have been demonstrated, including a reduction in memory and concentration, loss of psychomotor skills, and other impairments. However, the study also refutes the existence of a link between long-term cognitive decline and moderate marijuana use in adolescents.
What differentiates this study from others carried out to date is the larger sample of people, with 2,235 people of whom 24% claimed to have consumed marijuana at the age of 15.
We can deduce that only excess, and not consumption, is harmful to health.
