This proposed law isn't the first nor will it be the last attack on vaping.Taxation/regulation - IS - coming and not only from state/local governments but from the feds as well. Once the feds lead the way in regulating and taxing the industry our state/local governments will swarm us like locusts in a never ending barrage of taxes/increases and regulation. Concentrated flavoring will "always" be available for DIY, that's not going to be a problem as many (like Capellas flavor drops), are manufactured and marketed for food/beverage use, not for vaping. It's the liquid nic people need to worry about. Liquid nic is only produced by a few certified labs making it easy to regulate, tax and control. Post regulation/taxation, that $50 liter of 100mg nic could ultimately cost a thousand dollars IF its sale to the general public hasn't been outlawed altogether. RBAs and mods are also a potential concern since nearly all are imports and must pass through customs making them easy to ban, tax and or control at the federal level.
Fight these "proposed" laws, contact your representatives and let know your position/thoughts on the subject but don't procrastinate essential planning for the future. Remember, they can't tax or keep from you what you already own and have on hand. Liquid nic and concentrated flavors will not actually freeze but WILL keep for "many" years when stored in your freezer, the colder the better. RBAs and mods can sit in a drawer for decades and still be as good as new. That $15 FT RTA could be worth its weight in gold five years from now.
With "inevitable" government regulation/taxation, the golden era of vaping will soon end, gear and supplies will never be as cheap and readily available as they are right now. Plan accordingly, while you still can.
