They always smoke marijuana while they drink .They are used to drinking a lot of alcohol .They are a large person .None of the above choices .
Why is their friend able to drink so much ?
Alcohol just never seemed to be an intoxicating substance for him . He could drink extensively , the strongest liquor available ( and in fact his chosen beverage was Absinthe ) , but still remain completely sober . Marijuana acted much like an energy drink would to someone else .
