"Cannabis" is the category of drugs that derive primarily from the various species of
Cannabis plants. Two species that supply much of the abused Cannabis are
Cannabis Sativa and Cannabis Indica. Some jurisdictions as well as botanists don't recognize
Cannabis Indica as a separate species. The active ingredient in these drugs is
Delta-9 Tetrahydrocannabinol (THC)
THC is found principally in the leaves and flowers of the plant, rather than the stems or branches.
Different varieties of Cannabis plants have different concentrations of THC. A variety that has a relative
high concentration of THC is the Sinsemilla (the unfertilized female) plant, a type of Cannabis Sativa
having very tiny seeds. ("Sinsemilla" is a Spanish expression for "without seeds")
Possible Effects of Cannabis
Cannabis appears to interfere with a persons ability or willingness to pay attention.
People under the influence of marijuana do not divide their attention very well. When driving, they
may attend to certain parts of the driving task but ignore other parts. For example, they may
continue to steer the car but ignore stop signs, traffic lights, etc...
