when i use my vape sometimes my lungs will burn but not a hot/harsh burn more like your lungs are filled to the max with vapor, although it does get me higher than smoking its missing something from it as well, strait smoking gives a diffrent tyep of high which may be what you want more then the head high a vape gives you.

what i normally do is take a bowl or 2 from the bong then after about 20-30min take 2-3 hits off the vape and im fine the whole night with both types of high.
