Hog Wash.  Pot is dangerous.  It ruined my life.  It is a soft drug leading to stronger drugs.  It also removes inhibitions were people do things they would not normally do.  Usually immoral actions.  I was a classic pot head in high school.  You will never ever convince me that pot is good for the masses.  If people need it for a drug to reduce pain that's different.  Leave it with the pharmacy.  Get it off the street.  Again reasoning about this with someone under the influence of pot is impossible.  It likes telling a heroin addict they don't feel good after they shoot up.
