i've got some to add that aren't covered... more hints, then technical info...

first, smoke where you're comfterable... if you're paranoid before even lighting the j or bowl up where you're at, chances are you are not going to enjoy the high.

second, don't answer the damn door lol... i've had quite a few people get knocks on their doors and start freaking out... if you're smoking, and not expecting someone to come by and chill, leave the door closed... no where in law does it state you have to open the door, even if the cops are there... so just don't do it... go about your smoking and forget about 'em.

third, have everything you need... to me atleast, it's aggervating to have to get up every few seconds while i'm trying to relax... i'm sure alot feel the same... you know what you're gonna need, so have it there... grab the remote, make sure you got plenty to drink, lighter ashtray, (peice if using a peice to smoke out of) something to poke with should you need it (paper clip)..

fourth, if you invite someone to smoke, you better damn well offer them a drink... some people are timid and won't ask til they just can't take it anymore... be the curteous host and ask before even lighting, just to get it outta the way... (unless you're like me and they know they can just grab it..)
