Or gum. Or patches. Or lozenges. Or go buy another vape or recharge your battery. You'd have to go out and buy the cigarettes anyway. It's not like they magically appear in your home.
I can think of several gas stations, liquor stores and convenience stores that sell neither nicotine gum, patches nor lozenges. They all sell cigarettes, though.
Quite. Who the fuck wants to smell of smoke when you can just have lozenges or the gum? Also: actual cigarettes are prohibitively expensive in most countries.
