Take the average Joe that doesn't drink, smoke or do any drugs and fill him full of weed. Before he passes out he will have raided the fridge, spoke about some stupid cosmic sh**, became paranoid and then passes out.
Fill the same guy with alcohol, can't walk, can't talk, has insulted your wife, pissed his pants, puked and probably broke something in your house.
Alcohol has done far more damage to people than anything else in comparison. My two cents...
