im very confused.

i will say this:

Smoking- incinerates bud causing it to combust. In the process you are freeing about 10-20% of the THC in the bud, the rest gets destroyed because of the heat. You are also burning the biomaterial, which is the stuff that makes up the plant itself. This produces carbon based biproducts which you dont want in your lungs.

Vaporizing- uses a heat coil to raise the temp to the perfect amount to release the THC from the plant WITHOUT burning the biomaterial and without destroying much THC giving you around 80-90% of the available THC in a nice clean bag of air.
