I must disagree somewhat, if you worked in a lab where they analyze pot you would see what has been found mixed in. i.e. additives that i've heard of or seen are: pcp, cocaine, heroine, and an unforgettable mention formaldihyde which is not common but could be found in it. A little pot once in a while never hurt. If you saw "that 70's show" it was okay to air that program knowing that at least twice per episode they gathered around the table. If it was so terrible then the media would be contributing to its content just as the adult play on the soaps.
