It smells terribly, exposes others to negative health effects without consent and is one of the biggest causes of littering. Simply put it is a major nuisance with no benefits apart from profits for the tobacco/drug industry and addicts getting their high.
Could probably extend that to anywhere around minors in general too.
Alcohol is the same. Something like 6% of cancer deaths are attributed to alcohol. Its easy to make it look bad (and don’t get me wrong it is bad). Worldwide something like 80% of liver cancers come from Hepatitis.
Recent surveys in the U.S. have showed that 5% of parents have skipped hep b vaccines and another 4% have delayed the vaccination for hepatitis B.
Those aren’t directly comparable, but a person could drink every day of their life, and be 13 times less likely to die from liver cancer because a choice their guardian made.
