i think friends should always help friends out (so long as they are trustworthy and you know they dont intend to fuck you over)
however as with most gift giving it is important for that friend to hit you back with some smoke.
a lot of you may have had bad experiences losing shit loads of weed, but to be honest so long as you have a good time with them it doesnt matter
i would rather be sharing my smoke being happy with others than smoking it alone in my room
but that just be the way i see it, as my friends give back, cant speak for everyone.
