This is all good advice. What you want to avoid is negative pressure inside your mouth, meaning, don't SUCK on anything, including a pipe. Try to take diaphragm breaths if you do toke, and whatever you do, don't smoke cigarettes or joints. The smoke may irritate the site, but what you are mostly trying to avoid is the dry socket, which mostly happens from sucking on things or sneezing violently or stuff like that. Try eating it instead, if you can manage food.
