My dad had been smoking 3 packs per day and rolling tobacco 3 year ago he had 3 heart attacks and had 4 stents placed through his arm to his heart he was told if he smoked the stents would fur up and would kill him thank god for the vape industry taking off he would never have stopped without an ecig . I have tried them on and off but went for it big time with the tfv8 cloud beast and 4 days later I’m cigarette free I’m 44 and smoked si centre 12 13 year old anybody thinking about quitting get a mod a tank and a nice tasting juice and go for it you will be amazed how easy it actually is with this technology good luck people and keep off the stinkie tar cancer sticks
