Specific Drugs and Their Effects:
All forms of cannabis have negative physical and mental effects.  Several regularly observed physical effects of cannabis are a substantial increase in the heart rate, bloodshot eyes, a dry mouth and throat, and increased appetite.

Use of cannabis may impair or reduce short-term memory and comprehension, alter sense of time, and reduce ability to perform tasks requiring concentration and coordination, such as driving a car.  Motivation and cognition may be altered, making the acquisition of new information difficult.  Marijuana can also produce paranoia and psychosis.

Because users often inhale the unfiltered smoke deeply and then hold it in their lungs as long as possible, marijuana is damaging to the lungs and pulmonary system.  Marijuana smoke contains more cancer-causing agents than tobacco smoke.  Long-term users of cannabis may develop psychological dependence and require more of the drug to get the same effect.  The drug can become the center of  their lives.
