I have a cousin with the same
Social Anxiety Disorder as Williams. He hates weed, hates the taste, smell, and especially the social stigma, but he smokes canabis almost daily and claims it helps a great deal with his disorder. Aparently all the meds the doctors put him on had side-effects that he considered much worse than the disease, but the evil plant helps him function in the same way, minus the shriveled willie and baldness (or whatever the side effects were). I dunno if it's bull**** or not, but I tend to believe him when he says that without it, he wouldn't be able to hold down a job or leave the house.
