I smoked for about 55 years, until 2009, then switched to 12 mg e-cigarettes and have been using them since September 2009. My breathing and general well being have improved greatly. I had cut down from a pack a day to about two packs a week but couldn’t put them down completely. After I switched I have been smoke free for close to five years, and I no longer use tobacco in any form. It seems the tobacco industry has finally convinced the FDA to regulate this threat to their profits. Earl Mayhall, Marianna, Jackson County, Florida, 32446
