I understand it's use is illegitimate, however alcohol is far more dangerous to actions when consumed as well as long range health consequences; Again, whereas weed has mild relaxant properties which would be just what the DR. would order and in fact they do. But it's use illegal, still.
Not an advocate of either substances use, and most certainly against the consumption of alcohol, although it is legal!
Certainly if I were to pick between the two, to relax, alcohol would not be in the discusion...
