I am glad this is frozen at least for now. Seriously, this appears to be about tax income for the state and nothing else. It is designed to make up for the taxes we are not paying in analogs.
I don't think it's going away. They will impose a tax to whomever is the shipper which will be passed on to us Californians for online purchases (this cannot be reasonably stopped and they know it, so they will get some money from it) and I think companies would rather charge the tax than fund a fight with the state over anything.
I think, and this is just my personal opinion, that it is too late to ban personal vaporizer use in California or anywhere else. It has gotten too big. If they had tried as little as 5 years ago it may have succeeded, but now big tobacco has their fingers in it and our numbers are too big. What will unfortunatelly probably happen is only unflavored, tobacco flavored or menthol juices will be available (but with diy, we can flavor our own and no one will be able to stop it) and it will be taxed so high it will rival the cost of cancer sticks. I'll continue to do my part to stop that, but it may be a wasted effort in the long run. I will, however, continue to vape. Period. I am one of those who will, no matter how hard I try and have tried, continue to use nicotine to the end. And with vapor, the end will be further away.
I hope I'm wrong about the taxes and flavors, and, like I said, will continue to fight and to educate when I can.
