Yes studies say it's much safer than smoking, a big one by UK govt concluded it's 95% safer than cigs and now govt is giving vapes to smokers. Vape juice is mostly made on harmless base but have seen headlines about leached metal from coil found in studies. But, it should be much better than that of what found in cigs.This smoke Nord 2 is a great device. If you like the nicotine rush, do get the nic salt juice, not the freebase one
