i agree with the vaporizer idea if you have to be super-careful... no smell at all but you have to be a bit patient so do it if you're alone.

i smoke in a walk-in closet with a tube to blow the smoke through..no yellow rings on the wall though damn that sounds weird. i use a small pipe and take small hits that i hold in for awhile, make sure the weed stops burning before you stop sucking. got to get used to the small hits for indoor smoking.

lol so many ppl have posted theres no way the original poster still doesnt know what hes doing
