For decades, members of the marijuana movement in America have been experimenting with
Cannabis-infused edible products. Whether it was brownies or cookies, kitchens across the land began grinding in leaves and flowers of Cannabis to make a variety of baked products for those so inclined. From the very onset, Cannabis-infused edibles caused a controversy, as none of the formulators knew anything about how strong they were making their products, and therefore could not predict how anyone would react until they ingested. This trial and error was, until now, the only way a person could judge the strength and efficacy of a particular edible.

While a large number of compounds are present in Cannabis, the ones that truly distinguish it from other plants are known as Cannabinoids. These share a common ring-based structure that is just the right shape to engage with the Cannabinoid receptors in the brain known as CB1 and CB2, and while their exact function is still unknown, many secondary effects are well known. These receptors are present in humans as well as many other lower animals, indicating that Cannabis has co-evolved with humans, and it may even play an essential role in our physiology.
