I relapsed a lil over a month ago, and i've been smoking clear in my room, with the window open, mostly blowing it out the window. i live with my grandpa and he was out of town for a while but last week came home. he developed a cough and it's coming from his lungs. i started getting worried that maybe i was the reason. if i smoke in my room with a towel under the door crack, and i blow as much as i can out the window, will the residue still travel around the house and effect him? i also have family coming over for thanksgiving and i dont want meth particles on every surface. i was looking up these questions and the answers are so bipolar and unclear. some say yes duh (but it seems like they are answering from someone who has no idea what they are talking about or have never even smoked meth before and others say it's not a problem at all.

i just dont wanna hurt my pops, or ruin his house. is residue from carpet or walls enough to effect someone? or like can the small amount of vapor that does stay in my room spread through the house and make him sick?

before i ever smoked this bullshit i was hanging around people smoking all the time hotboxing cars and never felt a thing.
