I guess it's called a vape? It's a regulated box mod, specifically. People use them to quit smoking - I picked it up because I tend to smoke when I drink and the habit was starting to carry over into when I was sober, too, so I kind of use it as prevention. The nicotine also really helps with my anxiety (I use really low nic - 3mg). Full research hasn't been done into how safe they are, so if you aren't a smoker, they're probably worse than not inhaling anything at all, but if you're a smoker trying to quit, these are definitely a better alternative. If anyone wants more info, feel free to message me!
