I've read of some people working on reducing their nic level to either need less nic if obtaining it were to become a problem or make it easier to quit altogether if they needed to.
Other's are learning how to DIY. If getting ones favorite vendor nic juice was a problem they could mix their own and if nothing changes they can still save a ton of money even if they only DIY a portion of their juice.
Some are purchasing RA's. If obtaining attys or cartos or clearos were to become a problem they would have a juice delivery system to last a long time and if nothing changes they can save themselves some money since rebuilding RA's is so inexpensive.
Some are adding at least one all mechanical APV to their collection. A well built all mechanical APV could continue to work for a very long time without needing any repairs. Lets face it, electronic APV's arent going to last forever unfortunately.
Some are stocking up on extra attys or cartos or clearo in case getting those were to become a problem.
No new regulations are going to happen overnight so there will be warning IF major changes are going to happen. We've seen a lot of new vaping toys this past year and that will likely continue as long as it can. People do need to be careful that whatever they stock up on is going to be stuff they will use and wont become money wasted because they move onto something entirely different then they use at this moment.
I could be content with what I like now no matter what advances take place in the vaping world. My hubby is hoping to retire soon and its looking like I may loose my job at the end of June so for me its not just about what regulations the FDA puts in place. I simply may not have money to spend on vaping supplies in a few months. I already have a healthy stash of vaping toys that will last me years but I have taken an inventory and thought about what additions would benefit me in the years to come if I couldnt easily make new purchases either because of FDA regulations or lack of funds. Between now and the end of June I hope to add one more all mechanical APV, one more RA, and replace some of my nic that's over a year old now.
