This is a link to an excellent booklet that looks at 10 different public perceptions on Marijuana, and uses studies, data, and gathered evidence to change those perceptions.
Myths include:
Myth #1 Marijuana is harmless
Myth #2 Marijuana is not addictive
Myth #3 Marijuana is not as harmful to your health as tobacco
Myth #7 If I buy Marijuana I am not hurting anyone else
Myth #10 The government sends otherwise innocent people to prison for causal marijuana use.
