i used to smoke cigarettes,half a pack a day for six month before I got into vaping.I would smoke one every hour during work.Now that I am into vaping,I smoke almost every 15min,even when I am going to sleep I would bring my vape and smoke them to sleep.I calculated that I am on around a pack of cig now in contrast to my vape.I don’t have any problem besides dry mouth and have been consistently drinking water every 15min as I vape.I read that vaping is a lot healthier then smoking cigarettes,now that I vape one pack of cigarettes a day which might not be a lot to people who smoke 1-2 pack a day...I am not yet worried,but just want to share
