Marijuana can potentially cause which of the following conditions in susceptible individuals?

Marijuana has been associated with the onset of psychosis in susceptible individuals, especially those with a personal or family history of mental illness. Research indicates that THC, the psychoactive component in marijuana, can alter brain chemistry and increase dopamine levels, potentially triggering symptoms like delusions and hallucinations. This risk is notably heightened in individuals who may already be predisposed to such conditions due to genetic or environmental factors.

While marijuana can influence mood and anxiety levels, and it may contribute to or exacerbate conditions like depression or anxiety, these are not considered as directly linked to psychosis as the latter is. Severe headaches may occur in some individuals as a consequence of marijuana use, but they are not classified as a primary psychological effect like psychosis. Thus, psychosis stands out as the most significant and potentially severe condition that can arise in susceptible individuals after marijuana use.
