There is no mistake. Self prescription of dangerous drugs is drug abuse.

Causality between marijuana use and mental illness has been determined. That proves marijuana is a very dangerous drug.

Our choices and our values have a direct impact on our mental health.

Basic psychoanalysis relates the functioning of the mind to that of the body. The food we eat and our fitness to digest affect the health of the body. Similarly the information we are exposed to and our ability to process it affects the health of the mind.

In short, the ability to process truth feeds the healthy mind. The inability, for any reason, feeds the unhealthy mind.

All recreational drugs impede the minds ability to process information. Some effects are temporary while others are permanent. Marijuana stays in the bloodstream for months.
