I've been reading up on the safety issues with e juice and the consistent theme I've found is that vaping is almost certainly less harmful than analogs. That said, I consistently see people who step down in nic levels and increase the amount of juice they go through per day. I've also seen that the questions about health effects have little to do with the nic and much to do with the effects of inhaling pg and vg and flavorings/additives. My question is why step down the nic level and increase the risk with vaping more? Wouldn't it make sense to vape at the highest tolerable level and vape less?
