Men get more relief than women do from painkillers like morphine, according to some studies. New research with rats hints at a possible explanation: Male rats have more receptors for the drug in a brain region involved in pain processing. Although it's not yet clear whether the same is true in humans, researchers say the study underscores the need for more research on the sex-specific effects of pain drugs

NEW YORK, Nov 5 (Reuters) - Pfizer Inc on Wednesday became the latest drugmaker to abandon an obesity treatment that works by blocking the receptors in the brain that makes people hungry after smoking marijuana.

New research shows that CB2 receptors, a type of cannabis receptor, are present in the peripheral nervous system but not in the brain. The signficance? Now cannabinoid drugs that can be tweaked to affect only this receptor can be used for painkilling purposes without causing physical addiction or intoxication or any of the mild mental side effects know in recreational marijuana. Osteoarthritis in particular seems a likely place to apply this information.

The benefits for people who have had positive or even mystical experiences induced by the psychedelic drug psilocybin — the psychoactive ingredient in "magic mushrooms" — linger for as much as a year, according to the latest follow-up study of such patients.

Sit up, couch potatoes: the runner's high is real. Proving the yea or nea of the marathoner's mescalin has been difficult because, as one researcher put it, it's not such a good idea to give someone a spinal tap and then send 'em right off to run a 10K. Recently, someone came up with the bright idea of using PET scans (they copied off the dudes doing pain research).
This article is interesting more for the way in which the researchers applied existing technology to solve a problem than for the subject they're studying

Researchers at the Baylor College of Medicine have developed a vaccine that is currently in clinical trials that doesn’t fight what most consider to be a real illness or disease like cancer or AIDS. Rather, this vaccine stimulates the inoculated immune system to combat the illegal drug cocaine.
