If you ask why someone would do something unhealthy like smoking then perhaps you should also ask why people do unhealthy things like playing computer games which are very common in our community. Obviously people consider that the short term pleasure of such activities outweighs the health costs. For some of us the costs of such things aren't relevant. On any sort of IT industry pay the price of Coke doesn't matter and as a stimulant if it allows slightly more work then it will give a good return on investment. In terms of regulating tobacco I don't think that adults choosing pure tobacco products such as cigars has ever involved a significant portion of the population. It's cigarettes that have chemicals to make them more addictive that are advertised to children that are the biggest problem. If prohibition is ended by having government run medical centers administering heroin then it wouldn't encourage people to take up the habit. What encourages people to take it up is pressure from other addicts who want to make money dealing. Also to reduce drug use we could work on policies to make people's lives not suck. If things are going well for someone then heroin just won't appeal to them. -- Sent from my Samsung Galaxy Note 2 with K-9 Mail.
