yea weed def helps me. Especially if its smoked in a bong. It seems for the first couple hours i can almost relax to the point where i sorta forget about the w/d's and the anxiety i had before. But what i personally like to use weed for when in w/d is to aid my appetite. Yea it helps with anxiety a bit, and some like it for insomnia or nausea, but i think that the greatest thing about it is that it allows me to eat.
When you are in w/d , especially after the 2nd or 3rd day, most of the terrible symptoms you feel is from being dehydrated and malnurished. Smoking some bud allows me to pound down mass amounts of protein and carbs and it makes a world of difference. it is sooo important to eat when your in w/d. the less you eat, and drink, the longer and more intense your w/d's will be. There is no record of anyone every dying from opiate w/d itself. but people have died from malnourishment
