A question to you vapers out there

Thinking of getting a mflb for obvious reasons (more efficient, healthier) but I'm wondering about what affect vaping has on your high as oppose to smoking. As I understand it, vaping will just give you pure thc, where as smoking comes with a whole myriad of other cannabinoids (i think this is why you cant replicate all the affects of weed with a pill). So, to those ents who have smoked and vaped, how does the experience of the actual high differ?

P.S how does vaping affect your tolerance compared to smoking
