How to find out whether a party is a smoker or non smoker?
Answers: I'm not sure more or less blood but you can in a urine trial for nicotine.
I recommend the sniff test though, as it is only as accurate and cheaper.
their teeth will be yellow, desperate breath, and u can smell smoke near them even when they arent smoking..... as for test....
ask a doctor if they can do anything... maybe a llung check? or if the cilia within their nose looks adjectives up?
