We know that Pot is not addictive and the others are.
People with half a brain know this and people who are weak minded or they were told that Pot would make you crazy found out it was a lie and figured the information on the other drugs was also a lie so they moved on and get hooked.
Honest education could go a long way to helping with drug problems.
Truth is Pot was banned bot because of any danger, but because hemp threatened that paper mills of William Randolph Hearst, because of racism against Mexicans. Look it up if you don't believe me.
