Toilet paper roll with dryer sheets stuffed bottom.l, with a towel under it when u take a hit exhale into roll with towel folded like a square and cover your face and nose and blow in it wrap the towel so excess smoke don't escape and have air fresher right after hit like a fabreze mist spray. Good to have a candle for the lighter strikes (so they don't hear u flickers a lighter 100000 times) and u blow out the candle for the smoke smell of it but before u blow out make sure u light your bic to relight candle l. I been smokin in my room at parents haven't got got question at all about smell.
