Marijuana

What It Does
Smoking marijuana in pipes, bongs, or rolled like cigarettes are the most common forms of use. The chemical in marijuana that leads to its high is called delta-9-tetrahydrocannabinol (THC) which affects the user at the cellular level. The short term effects of marijuana include increased heart rate, memory and coordination loss, difficulty thinking, anxiety, and panic attacks.

The brain, lungs, and heart all suffer the effects of marijuana use. For the heavy and long-term users, the chemicals in marijuana cause problems in the brain resulting in irreversible memory deterioration and difficulties learning. Behaviorally, the user may also display more aggressive and angry tendencies. The lungs can be damaged by smoking marijuana much like the effects detected in tobacco smokers. Lung tissue may be destroyed and the user left with higher susceptibility to chest colds and coughs. Since the heart rate increases during use, the long term marijuana user risks damage to the cardiovascular system.

Arizona Statistics

Marijuana use sharply increased in 1993, but did not continue to grow in 1995. As for regular use, 22 percent of all high school and 9 percent of all junior high school students said that they smoked marijuana at least once a month in 1995. Among elementary students, 3 percent said they had tried marijuana in the past month. Parents estimated that 4 percent of Arizona youth use marijuana, whereas the actual use for elementary students was 3 percent, middle school students 9 percent, and high school 22 percent in 1995.

Straight talk about marijuana
"The memory of what happend that night scares me even now. I know all I did was smoke pot that night and I am sure there is a good chance it was laced with something else, but the whole point is that with illegal drugs, you just never know what can happen. I was completely naive and thought the whole 'I'm only having fun, its only pot' thing. But what I thought was only pot proved to change the rest of my life. All I'm asking is that you educate yourselves and realize you are not invincible--you are human."
