Firs of all I AM NOT A POT HEAD.
From my personal experiences, i say somking weed is alot less harmful to yourself, and others than being drunk. When i'm drunk i want to do stupid things, such as go out for a drive. Wen i'm high i have more control over my actions and body. In my case Weed > Alcohol. Thast why i dont drink, and the last time i somked was in october.
