POT SHOT

California researchers have shown in rats that a synthetic drug that mimics
the principal active ingredient in marijuana acts like morphine on an area
of the brain that modulates pain.

Cannabinoids are a promising model for new drugs because unlike morphine,
which can cause nausea and gastrointestinal problems, they stimulate the
appetite. Such drugs would be useful for chronic pain sufferers who have
trouble maintaining their weight.
