Ah, but that is different than simply being dumb as more is involved.
Most people use other methods today.
Edibles is a fav.
When baking edibles, brownies, cookies, etc, the baking temperature is normally 350F, which is around 180C, which is perfect. And when eating marijuana certain forms of THC which cannot be acquired through smoking are activated in the digestion process. So edibles are nearly 100% Efficient.
So, to be more THC Effecient, one should try and to burn Joint/Blunt slowly, and knock large amounts of the cherry, leaving a small amount burning, just enough to Activate the weed behind it. This theory also proves that blunts get you higher than rolling papers.
Tobacco, which is found in blunt wraps, burns slower, and at a lower consistent temperature, than the gums found in rolling paper. A lower temperature, with a slower burn means less of the weed is combusting, which means less THC waste. Joints burn too fast and too hot, so i recommend only using them when you dont have a blunt available and when you not home where you can use glass peices.
