Ahh yes, I had misunderstood what you were trying to say. Yes, alcohol and tobacco are some of the worst drugs there are and quite honesty I think they should be banned outright. A lot of people will be hurt by it, your wife for example, however the benefit would outweigh the negatives. I do understand that it is not a popular opinion and very many people would strongly disagree with me.
It is without doubt an extremely contentious subject, and you're right, opinions are divided. Politics and money play a huge part in it all so there's never going to be a simple solution to the worlds drug problems.
