Marijuana also casues respiratory diseases (7) and mental disorders, such as schizophrenia and other psychoses, depression, panic attacks, hallucinations, paranoia, hostility, depersonalization, flashbacks, decreased cognitive performance, disconnected thought, delusions, and impaired memory (8). Since marijuana impairs coordination and judgment, it is a major cause of accidents (9).
