Pot was not so much a trigger as a part of the ritual for me...if I had pot I wanted booze & cigarettes; if I had booze I wanted pot and cigarettes.
Initially tho, I started on pot as a teen, and came to alcohol about 10 years later. Pot lowered my inhibitions and made really dumb ideas seem good.
It also destroyed my life as much as my alcoholism did later on...so I vote no on all counts.
