I would bet they're going to need FDA approval and the samples shouldn't have been distributed. Even if the cigarettes with 'no nicotine' are marketed, who's to say there aren't other dangerous chemicals in them? Not to mention the recent issues with other products from China (lead containing toys, toxic baby milk). I don't think the FDA will allow ingesting anything into the body that hasn't been tested. I could be wrong though.
Even if they begin to market them, I would bet anti-smoking or other groups would launch concerns and force the products to be tested. You never know what kind of chemical reactions take place when ignited. Cactus could be perfectly fine until it's burned. But again, I'm just being devil's advocate.
I still hold this stock and would love to see them market their products globally. But where the cigs are concerned, I see potential for problems with regulation, at least in the US.
