There will always be work for a pharmacist/vaper although the best opportunities will be for those who can build mixes that have appeal - in other words good, successful DIY specialists with a pharmacy qualification who go professional.
The problem is that the FDA is tasked with shutting
vaping down, and in around two years they will have enough regulations in place, and an enforcement mechanism set up, to start closing down ecig businesses (unless they lose in the inevitable court actions). As a result, this is about the worst time to start a
vaping business as you may not recoup your investment before you get shut down.
On the other hand, the giants will survive while the small guys go under. This is because the FDA will bring in huge fees and incredibly expensive and complex compliance conditions. So if you're looking for a job, talk to Blu, NJoy or the big cigarette firms - they will be the only legal suppliers left on the mainland, all the rest of the trade will have to go offshore. Speak to one of the giants, then, and be prepared to relocate.
Unless - as stated - the FDA lose a lot of court battles, as we are now due for a restart of the legal battle between the ecig industry and the FDA. FDA vs ecigs, Round 2. We just have to hope to get an honest judge again, like Judge Leon; but overall it looks like an impossible task this time round. Everyone in power is desperate to protect smoking, it's the gravy train to end all gravy trains. It's worth more than a trillion dollars a year, and the money is spread around everyone at the top in order to protect the status quo. Some States will go bankrupt without smoking (the tax revenues and the MSA payments), so nobody wants ecigs turning the money tap off.
