Impossible. The weed in your pocket reeks even before it is smoked. I can home once after a trip and I could immediately smell the weed in my drawer in the next room.

Weed absolutely reeks. Period.

Vape, I find smoke to be obnoxious smelling and hard on my lungs.

Short answer is you can’t. It’s not just the smoke you blow out of your mouth— just lighting up the j alone is gonna stink up your house, there’s no real way around it. Get yourself a dab pen (dry herb vapes aren’t as bad as a joint but still stink) or even better, stick to edibles.

HEPA filter

This is not perfect… but:

I pack small bowls - small enough to entirely inhale till the embers go out, so that no smoke comes off the bowl after. Then crack open the outside door JUST enough to blow it all out the crack, then shut the door immediately. You’re basically kissing a tiny crack in the door, then shutting it. A fan won’t work - it’ll blow a bit of the smoke up and down and all over.

99% of the smoke goes into the lungs and out the door. The 1% still smells a bit though. If you cough, you fuck it up.

Then of course the weed itself smells - not much you can do about that. But it doesn’t seep into carpet/furniture as bad as smoke does.

Since you’re using a vape, try a cart (oil) instead and use the lowest temp you can stand. Do what you’re doing or try the window/door-crack method.

If you’re trying to hide it from others who live with you, you can’t. Just go find a spot outside and leave a hooded jacket and gloves there or in your trunk (but only if it’s legal and you can’t be harassed for smells.)

Only foolproof way is to buy edibles that are made elsewhere and keep them sealed. Febreze or dry shampoo can help a little with mild non-smoke smells after opening certain edibles.

Is you are someplace it is legal you can buy concentrates, eg: live rosin, which relativity smell like nothing. I vaporized weed for years; whatever room you are vaping in will smell like vaped weed. The best you can do is keep it to one room. With concentrates someone will only smell them if you open a container and bring it to their nose, or if they walk through your exhale. I use a an e-coil and a banger, the alternatives are to use a butane torch or a e-cig typle device.

Boof it

To make a vape smell even less, filter through a water pipe, but also, it’s still going to smell, light a candle, get deodorizers.

If you have a split AC unit you can put activated carbon mat on top of the inside unit where it takes in air. Clears all smell from inside that room especially if it’s a small space. You could probably make a similar contraption with a box fan.

During it’s going to smell the whole time, unless you have super good ventilation. Even then it’ll smell but it at least won’t start seeping into other rooms you don’t want it. After that it’s just time. As long as you aren’t baking a place out weed smell won’t hold in fabrics and other items like cigarette smoke does so again it’s just time to air out.

When I smoked I’d use an air purifier, with a window open and fan running, as well as using a sploof (slang for this might be different where ur from) and sometimes burning a candle. All those combined and being sure to dispose of your ash quickly should reduce the smell. Your best option is a dry herb vape though, and that’s better for your health too

Back in the day we used to stuff dryer sheets in an empty toilet paper roll.

I just googled it and it’s called a “sploof.”

Anyway, you blow your exhale through that, and it smells like dryer sheets.

dont smoke anymore, but back in the day I used to use a plastic activated carbon fish tank/aquifer filter with scented dryer sheets stuffed in the empty spaces.

take a hit, hold it for as long as you can to absorb a lot of the smoke, then blow through the filter.

I’ve always had the idea of a small room or tent, with a carbon filter exhausting outside. While your clothes may smell, the majority of the smoke is filtered and thrown outside.

Edibles.
