My first convert was not too long after I quit tobacco myself. I use 808's, the cigarette "look alike," but it happens to be one that I found after trying four others. I like the 808's for 2 piece instead of 3 piece use, and I chose to stay with the cigarette look alike because I needed to rid myself of 40 years of ritual, not just the smoke. I am still using my preferred 808, and this company now has a mid size battery with 808 threading so I don't have to look for adapters for my big batteries. I use both.
After a month tobacco free, I couldn't see not trying to help others quit, too. However, as said in an earlier post, if the person isn't truly ready to give up tobacco, it won't happen, no matter the device. Anyway, I put together four "loaner" kits for those who wanted to try and quit smoking and were willing to try an electronic cigarette. I used two 808 batteries from my preferred supplier, a usb charger, and three cartos of different flavors - one menthol, a Camel clone, and an RY4 - all in 18 mg, for each kit. I loaned one of the kits to another worker in my building for over the Easter weekend because she and her husband were going to visit relatives that didn't allow smoking at their home. Both she and her husband smoke but want to quit. When they returned, she brought back the kit, only one of the cartos had been used but she said both she and her husband vaped that carto, and they both liked it. I gave her a business card and a coupon code for the supplier, and they are now both happily vaping and not smoking. They plan on quitting vaping eventually as well, but they have stopped tobacco and that is what it is all about. The woman in turn has converted one of her friends, and on it goes. It is the ripple effect and a very beautiful thing.
I don't care what they end up buying, as long as they end up quitting tobacco. The ripple effect will take care of many more. All I'm doing is providing a loaner kit and a little bit of knowledge and I let them choose their own devices if they want to try something other than an 808. In the meantime, the loaner kits are available from my desk drawer, and if they really like the 808 batteries, I'll even sell them the loaner kit at cost to keep them going.
