The smell of vapor doesn’t linger or travel as far as smoke would. It won’t stick to your clothes either. A piece of gum or a breath mint after a vape session should be enough to keep the smell of weed off of you. However, the vaporization process can be smelly so you’ll still want to towel your door and use a fan.
The best devices for keeping the smell of weed to a minimum are THC cartridges filled with oils that no longer have the natural scent of cannabis.
Distillates are ideal because terpenes are removed during the distillation process. Many cartridges reintroduce terpenes later on in the process but some don’t taste or smell like cannabis.
The smell of vaporized cannabis or cannabis concentrates isn’t as intense as smoke outdoors. As long as the cloud of visible vapor isn’t traveling directly towards someone nearby, nobody will know you’re getting high.
You can take puffs when nobody is looking and put the vaporizer in a pocket when you’re not hitting it.
