There might be a good end-around in the US southwest, a plant called “wild tobacco”. Nicotiana rustica, is the strongest of the tobaccos, and unlike typical tobacco, which is about 1-2% nicotine, it is 9% nicotine. It grows wild and needs little maintenance.
While smoking it straight would be a big kick, it would probably best be blended with some tobacco substitute, or blended with tobacco to be a “booster”, delivering a lot more nicotine so a smoker would smoke less overtaxed tobacco.
Importantly, it isn’t regulated, and no license is required to grow it, and best of all, the anti-smoking crowd has likely never heard of it, or certainly never seen it.
You misunderstand. You are addressing an anti-smoker.
