anyway id say that vapor is much better than smoke. first of all, lots of cannibinoids responisble for the downer of a high dont get vaporized so there is not much of a dreamy feeling downer at all. its almost 100% more safe than smoking. smoking marijuana is not good at all for your lungs. not as bad as tobacco, but if your smoking for years and you look at your lungs, they look similar to a tobacco smokers. ummm what else......you use less weed and you get higher. you have more of a body high and the high is also more active just like tekno said. anyone cant really say anything about comparing smoke to vapor unless you have done what i did. suddenly stop smoking and only vaporize for like 2 months. then smoke once and you will notice a big difference. your high will not feel as clean at all, the smoke will be thick and harsh, and you will feel way more out of it than u remember. but then again ive switched back and forth a lot and i cant tell as much of a difference as i did before. you cant just vaporize once your first time and evaluate it because the high will just feel like the same to almost anyone. a good example of this would be just like watching vhs tapes and switching to dvd. now go back to vhs and you notice a big difference you didnt before.
