I recently picked up a good convection vaporizer and I think it's the greatest thing since papers. I can get high on half the amount of weed, so it'll pay for itself in a couple of months. There is a distinct difference in the quality of the high between vaping and smoking the same weed. If I roll the weed up into a joint and smoke it I get high but I also get confused, slow, sleepy, lose my short-term memory, and find it difficult to organize my thoughts. If I vape the same amount of weed I get twice as high but remain amazingly clear-headed, which is exactly the kind of high I prefer. It's very similar to the effects of certain off-topic fungi. I'm wondering why there is such a dramatic difference. I think it's because whatever components of the weed that produce the annoying side-effects are not getting included in the vapor. Does anyone have more concrete knowledge about the difference in the high between vaping and smoking?
