Thanks Luch! You've explained this great in recent PM's. I've actually been using that technique and did so last night with great results. But I used cloud on max temp, and just covered the bottom of elb. Only one hit/cloud but I'm able to hold it long and exhale a satisfying cloud (not huge). I'll try tonight with a lower temp and see what happens.
My problem and almost fear with using the small cloud technique for more efficient absorption is that I get a small buzz that is quite unpleasant. Almost like a 1/2 high, and then I get nausea. If I hit it hard and fast this doesn't happen. I'll try the fruit juice like you mentioned in another thread.
It sounds like your a lot of the thc is converting to cbn due to using such a high heat, and causing these effects. When you inhale fast, you are cooling off the herb inside the bowl a little more so less is converted, which is why it doesn't happen when you inhale hard & fast. Also more air is diluting the vapor so you take in less cbn. CBN isn't totally bad, but too much of it may not be what you want. Just lower the temperature, then inhale nice, slow and steady to keep the vapor from being too diluted while also preventing too much thc to convert to cbn. Here's more info on CBN:
The video leaves out the fact that oxygen is the main thing that causes the thc to turn to cbn, not just heat. This is why using such a high temperature in cases such as vaporizing or smoking, a lot of the thc converts to cbn and gives the lethargic, relaxed type high. If that's what you want then cool, but if you want just a "fresher" high lower the temperature and inhale nice, slow, and steady.
A couple of techniques you may like is doing the 12 o'clock technique I mentioned, then when you are almost done, raise the temperature to max, to get the cbn high as this can cause the high to be a little stronger. Have fun
The other is to use more of the herb(.10 grams) at once to get the quick rush type of high, then for the next session right after the first one, use the divide technique(.05 two times), and on the last .05grams raise the temperature up to max to get the cbn high. This is for when you want to have a real good time.
