I think the argument is that vaping is far more addictive for young people because of exactly what you say. Does not feel harmful and they end up very addicted at higher doses of nicotine than cigarettes
so let it only be sold to adults, sure. I'm just saying that equating vaping to smoking is absurd, because it's not nicotine that breaks your heart and your dick and gives you cancer, it's the smoke.
Vaping is still objectively horrible for the lungs.[0] And I would be slower to argue about the cancer. Do we know yet? It is a young vice.
