Marijuana In Detail.

Marijuana In Detail Marijuana causes long-term changes in the foreland similar to those seen with other drugs of abuse . . . Back in the 1970s, zoology experiments led to groundless fears that marijuana blew holes in head tissue. The experiments organisations ilk NIDA now fund be more(prenominal) modern only when the contr all oversy still rages. George Koob, an addiction researcher from The Scripps look into Institute in La Jolla, California, margin calls the new message from the animals is childly: The more we discover roughly the neurobiology of addiction the more putting greenality elements were seeing between tetrahydrocannabinol (tetrahydrocannabinol, the main active division in cannabis) and other drugs of abuse. And for Koob, one of these newly discovered common elements is marijaunas ability to trigger chemical substance changes in the head that lead to strong onanism symptoms. In humans, rough researchers claim to see clear evidence of insomnia, anxiety a nd still flu-like symptoms in heavy cannabis users who abstain. But if theres a consensus, its that symptoms are tame and variable. By contrast, Koobs rats are shivering wrecks. Does this mean marijuana is more addictive than we think? Not a bit of it, says Roger Pertwee, a university pharmacologist and president of the Cannabinoid Research Society. Thats because those symptoms arent so much spy as manufactured. The animals are injected with high doses of THC, then injected with a chip chemical to block cannabis receptors in the wizard. Without the block, the sharp detachment symptoms cant be seen because cannabis clears so slowly that even to a great extent doped rats are likely to mystify a quench wind down. Another debate rages over animal studies into the short effects of marijuana on brain chemistry. Heroin, cocaine, alcohol and nicotine tout ensemble trigger a pile in the chemical dopamine in a niggling midbrain structure called the core accumbens. Many resea rchers... !
