Personally, I don't give a rats ass whether smoking (tabacco or pot) is illegal or not. If you want to do it, do it somewhere else. Do it in your car. Do it in your own home. Just don't do it in a public place. You may choose to run a crackhouse, or a business that allows smoking or whatever you call it, it comes down to the same thing. You opened a business that allows other people to hurt their patrons against their will. If the business owner wants to run a *public* establishment where any person may choose to enter, then they should not be assaulted against their will. If the business owner wants to open up a shop that says "for smokers only" (such as the cigar smoking rooms in california) then clearly that is ok. It is clearly marked that it is not a public place, it is for smokers only. But to open an establishment and to mark it as a non-public location is tantamount to a "whites only" sign. Most people are not going to want to go in there.
