As the article states.. A joint looses a lot of THC due to the cherry and ash.
I'm a big proponent of higher tempeirature vaping. I generally stay between 400F and 440F. At the higher temperatures I find the effects stronger with a body high similar to smoking. That said, I totally disagree with the last paragraph of the High Times article basically stating that all vaporizors will not combust based on the fact that true combustion doesn't occur until around 554F (290C). I don't know where they get that information. That makes no sense to me..
I agree with the higher vape temps. I think it's closer to smoking effects because you're combusting "some" of the other ingredients just as you do when you smoke. It certainly feels stronger to me.
