tobacco is harmful.
but no one country completely bans it.
China doesn't ban it either even if everyone in China knows its harmness and
sees that many and many people die of it.
Can anyone here think about the dialectic mechanism of the problem?
why does no country ban it completely and save its people
but instead waste a lot of money on Ads to advocate its harmness?
Is it difficult to ban like a curfew
or is it just a joke?
