Marijuana is an addictive drug with significant health consequences to its users and others.
Many harmful short-term and long-term problems have been documented with its use:
The short term effects of marijuana use include:
memory loss, distorted perception, trouble with thinking and problem solving, loss of motor skills, decrease in muscle strength, increased heart rate, and anxiety.
In recent years there has been a dramatic increase in the number of emergency room mentions of marijuana use. From 1993-2000, the number of emergency room marijuana mentions more than tripled.
There are also many long-term health consequences of marijuana use. According to the National Institutes of Health, studies show that someone who smokes five joints per week may be taking in as many cancer-causing chemicals as someone who smokes a full pack of cigarettes every day.
Marijuana contains more than 400 chemicals, including most of the harmful substances found in tobacco smoke. Smoking one marijuana cigarette deposits about four times more tar into the lungs than a filtered tobacco cigarette.
