Its western half is primarily an arterial street, named Lake City Way and Bothell Way, that follows the northern shore of Lake Washington; the eastern half is a grade-separated freeway that runs between Woodinville and Monroe. SR 522 connects several of the metropolitan area’s major highways, including Interstate 5 (I-5), I-405, SR 9, and U.S. Route 2 (US 2).
- Tetrahydrocannabinol (Wikipedia)
Tetrahydrocannabinol (THC) is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C21H30O2) describes multiple isomers, the term THC usually refers to the Delta-9-THC isomer with chemical name (−)-trans-Δ9-tetrahydrocannabinol. THC is a terpenoid found in cannabis and, like many pharmacologically active phytochemicals, it is assumed to be involved in the plant’s evolutionary adaptation against insect predation, ultraviolet light, and environmental stress. THC was first discovered and isolated by Israeli chemist Raphael Mechoulam in Israel in 1964. It was found that, when smoked, THC is absorbed into the bloodstream and travels to the brain, attaching itself to endocannabinoid receptors located in the cerebral cortex, cerebellum, and basal ganglia. These are the parts of the brain responsible for thinking, memory, pleasure, coordination and movement.
