It is safer. When you vaporize, you (hopefully) only vaporize the molecules that you want. The machine should be set at a temperature that is low enough to vaporize only the THC and CBD. No carbon, no icky tar, no lighter fluid. It is even better if you can vaporize an extract. You begin with the plant, extract the molecules that you want, and then vaporize said extract. Filter this vaporization through water since the molecules that you want aren't water soluble. This also cools down the vapours. It is a lot safer than blindly setting a plant on fire. The downside is that you will pay a premium in order to get quality medicinal extracts and you will need to invest money ($500+) in order to get a decent vaporizer.
