I'm tellin' ya man, this stuff is amazing. Go here and order this:

Also, pick up some "fog juice" from the same site. It's propylene glycol with flavor and has a small amount of nicotine in it. PG is a food additive and the stuff they make stage vapor with. Get a flavor that sounds good to you. I hear the Red Heifer is good stuff.
When you check out if you use the code "vapeatron" you will get 5 or 10% off. Can't recall which.
Basically the device is a rechargeable battery, an "atomizer" that turns the fog juice into vapor, and the tip piece. When they come, the tip piece works as a cartridge that has a spongy material that holds the juice. I just take the spongy part out. When you are "vaping" you just take the tip part out and drop a few drops of the juice onto the atomizer. Put the tip back on and vape away. 3 drops last about the length of one cig. The vapor is odorless. It looks like smoke but isn't because it's just vaporized fluid. Nothing burns. No tar or carcinogens.
I smoked for over 10 years and "quit" a number of times. I haven't had a cig in over 6 months since I started using this.
