Conclusion 

According to research studies, marijuana use causes aggressive behavior, causes or exacerbates psychosis and produce paranoias. Нese eوٴects have been illustrated through case studies of highly publicized incidents and heightened political profiles. Нese cases contain examples of repeated illustrations of aggression, psychosis and paranoia by marijuana users and intoxication. Ultimately, without the use and intoxication of marijuana, the poor judgment and misperceptions displayed by these individuals would not have been present, reducing the risk for actions that result in senseless deaths. Import to these assertions, is that the current marijuana is far more potent in THC concentrations, the psychoactive component. Accordingly, and demonstrated in direct studies, more potent marijuana results in a greater risk for paranoid thinking and psychosis. In turn, paranoid behavior increases the risk for paranoid behaviors and predictably associated with aggressive and violent behaviors. Marijuana use causes violent behavior through increased aggressiveness, paranoia and personality changes (more suspicious, aggressive and anger). Recent illicit and “medical marijuana” (especially grown by care givers for medical marijuana) is of much high potency and more likely to cause violent behavior. Marijuana use and its adverse effects should be considered in cases of acts of violence as its role is properly assigned to its high association. Recognize that high potency marijuana is a predictable and preventable cause of tragic violent consequences.
