There’s got to be some technology that does this. No sploofs!
Currently i crack a window, put a small square fan in it, and blow my exhaust through the fan. I use a vaporizer which cuts down the smell a lot, but there is still a lingering odor the night of, and sometimes the following morning.
I would prefer no odor at all, immediately. Any help is appreciated.
I can’t vouch for the fish tank filter part, but my friends and I did use the dryer sheets trick with pretty good success back when we were teenagers. We’d just stuff a ton of them into a toilet paper or paper towel tube. I also had a pipe with a lid that slid closed which let you stop smoke wafting out of the pipe after you took your hit.
