“cu de bebado não tem dono” havent heard that one in a while.

depending on quantity, it does apply to weed somewhat too. set and setting definetly applies if you want to get zooted off of softer drugs too (alcohol, weed), doubly so if there are people potentially looking to take advantage in any way. if you are in a new situation with new people, take it very very very slow, or preferrably not at all.
