Age Limit on smoking Legal substances?

Taiwan recently banned smoking in most places, most places except home that is. I was surprised, but it's a good step towards stopping smoking. I've always hated it and I am against it, but I guess it depends on which view you are standing from.

Even though it is a legal age limit in the United States, I think it should be enforced more. A couple of years ago I had a really close guy friend who picked up smoking. I eventually stopped associating with him due to him just smoking around me everywhere. One time he even had the guts to ask me to buy filters for his smoking.

There should be no advertisements about tobacco products in youth, period. Of course, we can't really stop it. If anyone reads the manga Nana, I'm sure you're aware of the constant...smoking that never stops in it. Sure I love the series, but the smoking just gets to me. It's directed at a more mature women audience, but still.

And I don't think there should be a "LET'S BAN ALL SMOKING". After all, some people depend on the business. It should be like Taiwan, where smoking is banned in most places.

Legalizing marijuana reminds me of China and the Opium Wars.
