It is a ridiculous thing, and fit for a satire to persons of judgment, to see what shifts these formalists have, and what prospectives to make superficies to seem body, that hath depth and bulk. I speak of the north shore of Tahoe, where one can count the scales on a trout at a depth of a hundred and eighty feet.
Marijuana in the Body. Every time someone smokes a marijuana cigarette or ingests marijuana in some other form, THC (delta-9-tetrahydrocannabinol) and other chemicals enter the user's body. The chemicals make their way through the bloodstream to the brain and then to the rest of the body.
The psychoactive ingredient is nicotine, a stimulant, but more than 4,000 other chemicals (2,000 of which are known to be poisonous) are present in cigarettes. Tobacco is a nervous system stimulant that triggers complex biochemical and neurotransmitter disruptions. It elevates heart rate and blood pressure, constricts blood vessels, irritates lung tissue, and diminishes your ability to taste and smell.
