Well, I am sure glad you can't get addicted to coke. Must have been a bad dream. Hey, can you get my house, my wife, my job, and all of my personal possesions and money back? Since you are sure people don't get addicted to coke, should'nt be a problem huh? Why don't you go to an NA meeting and announce that cocaine does not cause addiction, I am sure they would love to hear the news.
Cannabis has ZERO physically addictive properties, only psychological. Perhaps the reason you wake up irritable and tempermental is you are an irritable and tempermental person. You will very likely prove that with your reply to this post.
