man, its just getting high, who the hell cares? they are idiots if they want to stop you from doing something you like, its not going to hurt you. just be like, 'i appreciate your friendship and everything but im still going to get high, its something i like to do although you dont. you should accept that and if you really dont want to be friends then i feel sorry for you'. that should probably work.

that is, if you choose not to stop
edt: if you decide to stop, make them quit cigarettes too. its only fair :thumbsup:
