Marijuana distorts what is stored in the memory. It lies to the user. Smoking marijuana decreases the chance for a naturally satisfying life. It is an especially harmful drug for young people. Just when teens and young adults are searching for motivation and the best way to achieve their dreams, marijuana robs them of motivation.
Young people do less, learn less, and become less capable.
Smoking marijuana drains self confidence and arrests the development of confidence in a person's own ability to get natural rewards out of life. Drawn into the illegal drug culture, users are then available for those who are pushing other drugs. Addictive Marijuana produces an artificial feeling of pleasant relaxation. When the drug comes in, it stimulates the reward center. This short circuits the survival mechanism, because the reward center can't tell the difference between the drug and the natural chemical messenger.
