I wouldn't be upset personally if they completely banned cigarettes and alcohol for that matter, as someone who does neither and doesn't like being around them. It makes more sense than marijuana being illegal.
However I wouldn't actually do that. Its a pretty big tax boost after all, hate to lose that revenue. What the sensible thing to do in my opinion is just get it over with and legalize pot already and tax it. Everybody knows it's less harmful than both of those, and less intoxicating than alcohol. What's the big deal? I'm not saying legalize hard drugs, but if this is such a free country why are we still criminalizing something less harmful than what we already allow?
Then we ban something deemed unsafe that you want to use and you blow up. How dare they ban that, you might say. Perhaps we ban the sale of salt and all fast food because it makes large numbers of fat people with heart failure right round the next corner.
Perhaps we ban alcohol. Kills tens of thousands of people in one way or another. We all know an alcohol bans have worked in the past, right?
Explain why we should ban smoking but legalize pot; a product that must be smoked. Seems rather odd that we make legal something that not only hurts your lungs (Second hand pot smoke perhaps) but damages society to some extent. And it is smoked, so what about the idea that they ban smoking because it is dangerous, but legalize a product that will largely be smoked?
Would you get behind my plan to make sales of hard drugs legal? Clean heroin is something you can live with for many years. If the heroin is free from adulterants and at a consistent strength, you can actually live with the habit for a very long time.
I believe the UK government tried this in 1960 or so. Clean heroin, reasonably priced and delivered through sterile syringes. Some experts say you can quit heroin cold turkey but you can't just quit alcohol (assuming a serious long term drinking problem) without serious complications. So in a way, heroin might be safer than alcohol.
Or, we keep pot illegal and make the smoking laws reasonable? Give people the right to smoke in certain areas and let a business owner decide if he or she wants to allow smoking in his or her place of business. Let us have smoking rooms. Let US decide rather than a bunch of morons that simply want us to die off sad and unhappy.
