" Varenicline received a "priority review" by the U.S. Food and Drug Administration (FDA) in February 2006, shortening the usual 10-month review period to 6 months because of its demonstrated effectiveness in clinical trials and perceived lack of safety issues. The agency's approval of the drug came on May 11, 2006. August 1, 2006, varenicline was made available for sale in the United States and on September 29, 2006, was approved for sale in the European Union."
It took 6 months to deem Chantix "safe" even tho it clearly isn't. But it is legal and making billions.
Cigarettes clearly are not safe. But again, legal and making billions. Better yet, no prescription required.
Vaping - It's been studied for a hell of a lot longer than 6 months, but not nearly as long as cigarettes. The vaping community doesn't have the funds of BT/BP to prove its safety, however BT/BP have spent untold fortunes to disprove their safety, unsuccessfully.
I'm not aware of a single vaping related harmful side effect or death. Sure there is a harmful side effect for BT/BP as vaping in it's current state doesn't fatten their wallets as they would like. I also understand there probably have been a few vaping related deaths. I'm sure some poor soul crashed into a tree and killed himself while digging around in the floorboard for the mod he dropped.
I understand that the FDA can't give eliquid its stamp of approval without pretending to regulate it. I understand there is big money against it. I know it all comes down to money. I just hope that the government can at least act like it has a little self respect and not just bend us all over for a good screwing from BT/BP.
If the big guys have their way, eliquids will be so expensively regulated, taxed, whatever that they will be the only ones able to produce the stuff and many fewer people will be able to actually purchase and use the stuff. As it stands right now, small businesses are popping up every day. People are achieving their dreams, people are being employed, and lives are being saved. The regulations the government settles on should allow those small business to succeed and continue to contribute to our communities and society as a whole. They shouldn't be regulated to extinction.
I don't think anyone who doesn't smoke should start vaping. No more than I think anyone should start smoking. I do believe vaping is a great stop smoking aid. Vaping is the only stop smoking aid that basically satisfies every aspect of smoking, allowing those of us who are having the most difficulty quitting, to actually stand a chance.
