Yeah orangutans are pretty damn big and they are very strong, a joint may be too small for them. So a blunt wrap would probably be more suitable. Capuchins can be pets but I have heard they are a lot of work and always get into and destroy stuff. Same could be said about an orangutan lol imagine having one of those living in your house.
I was watching a nature channel at my grandparents house and the show was talking about how these orangutans would get into pot fields and steal pounds of weed and run off with big colas into the trees and eat them. So they already have a fond liking of the plant.
