does this friend smoke cigs? it may be easier to start with a normal-sized joint.

if they have never inhaled any sort of smoke, it may be better to use a bong...put ice in it so they get the coolest smoke possible, and ease any throat irritation. make sure they stop while they cough though, they will cough directly into the bong and spew water from the bowl! that happened to me once, it sucked. usual punishment for that is to put flame to the wet bowl and suck until its dry...it tastes like royal ass
