If I remember correctly, Crittery didn't say he was an alcoholic, just that drinking was causing him some anxiety and depression and was looking to cut back. He really wanted to quit smoking pot and cigarettes. I'm not condoning him drinking, but I really don't thinks he has a problem stopping. Just some of the chemicals he is using have made him try and see if life for him would better without them.
Confessing you are drinking when you aren't an alcoholic probably will be treated just as badly as if you were in this forum.
But drinking does make it easier for the smoking habits to come back.
