should minors be allowed to smoke/possess tobacco?

No.

can some of the 'no' people enlighten me as to how this could/should be enforced?

In the future "seven years from now," America has lost the war on drugs. A highly addictive and debilitating illegal drug called Substance D, made from a small blue flower, has swept across the country. In response, the government develops an invasive, high-tech surveillance system and puts in place a network of informants and undercover agents.

Loved that movie.

Anyway, just focus on the purchasing aspect. It's really not that hard to bust shop keepers for selling it to high school kids (or adults purchasing it for them). Treat it the same way as alcohol, basically.

soap, deodorant, hair spray, Johnson's Baby Shampoo, talcum powder, and hot dogs all contain carcinogens.  should their consumption by under 18s be banned?

Even assuming that smoking was no worse in terms of cancer risks (obviously not true) there's still heart disease, emphysema, brain damage, premature skin aging, etc. associated with prolonged use. I'd rather not pay for the costs of that because some 12-18 year old kid decided to puff up outside of class.

The difference in carcinogens between soap and a newport pack is like the difference between a bb and a .45.
