This summary of the info available in 1972, makes it look like it might be a good idea–
There is no doubt that some individuals and some small social groups give up alcohol altogether after discovering marijuana. . . The middle-aged marijuana smoker in the New York area. . . , is likely to “use marijuana precisely the way he previously used alcohol, and there are now middle-aged circles in which the drinking of liquor has almost disappeared.” A forty-year-old financier told Blum over a glass of nonalcoholic mineral water: “Well, I can hardly remember the last time I saw a drink at a dinner party. In fact, I can’t remember the last time I had a drink.
Another observation:
Perhaps the one major positive effect of the drug [marijuana] is to cut down on the use of alcohol. In the last few years it is rare for our student infirmary to encounter a student who has become aggressive, disoriented, or physically ill because of excessive use of alcohol. Alcoholism has almost ceased to [be] a problem on our campuses.
How sad that I took up with alcohol, instead of smoking weed. . . .
