From someone who has smoked and quit, I was really blind sided by how addictive nicotine was. People talk about adults and what they put in there body but nicotine really is a different monster
What I don't see is why smoking should be the main nicotine delivery device when it can easily be done without the cancerous smoke.
Isolated nicotine is apparently not cancerous. We just choose to enforce the continued coupling of nicotine and cancer, and refuse to permit alternatives that decouple if from cancer if their dosage isn't pitiful.
"Either get the weak alternatives, or the cancerous ones."
The moderate non-cancerous alternatives are illegal.
