I thought vapes made thc into vapor(aiming to get the temp around 370 , in order to get vapor instead of smoke), as I thought actual cannibinoids have a higher burning temp, and you get more cannaboids when smoking with flame.
there are quite a few reasons to vape, one , is some people get higher off of a less ammount of weed, some people use them because of asthma. But Vaporizers don't BURN the weed, they turn the thc into a vapor, and usually, you're left with the brown vaped bud (duff is what I've seen it called quite alot), and that can be used in butter, but I usually use 3 times the ammount in weight that I'd normally use when cooking butter, works fine.
