autistic person here, I still don’t get why people start. Like, I get that once you start you are physically addicted by the nicotine, but why even start? You don’t look cool, you don’t look tough, you only look like a dumbass who’s gonna go broke buying cigarettes, die in their 60s, and spend a painful life while reaching it because you are always exhausted and out of breath
Like shit, do weed or LSD, at least you’ll have a nice time, but cigarettes are just all downsides
methane doesn’t have an odor, you linked to the data sheet of trichlorofluoromethane, a completely different molecule
The gas in your house is artificially made stinky so that people would notice leaks and blow their house up, which happened a lot back when the stinky chemicals weren’t added and it was odorless
