Absolutely I’d start vaping again. Because I started vaping before it was the cool thing to do, using it for it’s originally intended purpose: to get people off cigarettes. Vaping might not be safe, but I’m fairly confident that it’s safer than cigarettes.
But if I could go back to before I smoked…no, I wouldn’t start. They are ridiculously addictive. There are plenty of stories of heroin addicts that managed to kick that habit but still struggle not to smoke cigarettes.
