Since I started vaping about 2 months ago, I have become addicted doing it almost constantly. A safe cigarette is what I have been waiting for. But I am not naive. There may be health risks. Has anyone seen any credible studies showing they may be a risk to yourself or others? I am ignoring the Italian study that only had 13 test subjects for 10 minutes. I know they are better than analogs but has anyone seen anything negative about ecigs?
