I may be able to add some valuable information to this topic.
We, as a human species, have evolved to have an independent physiological system within us called the endocannabinoid system. So, just like our cardiovascular system and respiratory are independent systems. The endocannabinoid system allows the 111 currently known cannabinoids from the cannabis plant to bind to it. Under normal circumstances, when the body isn't stressed, is sleeping well and the nutritional density is there to support efficient function, the body will produce its own cannabinoids. When it's not, the body develops an endocannabinoid deficiency and can't not properly self- regulate its own daily functions. This is easily seen in the number of people with chronic insomnia, for example, which is often completely correctable with the correct strains of cannabis plant medicine.
Consuming cannabis in edible form is 10 times more potent than smoking or vapourizing cannabis.
Your next evolution will be to "eat cannabis" @kevinwong! (It's a different experience yet again and produces some of the best "high-ideas". LOL, literally.)
