We just had a friend visit us over the weekend and she was so interested in my pv she now wants me to try to convince her husband to give one a shot. I do not know if he will be interested or not. Smokers have to be ready to stop, or at least ready to make a change. If they are not ready they will see every possible problem with our vaporizers and there is no way at all we will be able to change their minds. When they decide it is right for them, then they will quit.
