What is Marijuana?•Marijuana (mj) comes from the cannabis sativa plant, also known as the hemp plant. It is grown all over the world, especially in tropical climates.•Mj is a mixture of the plant’s crushed leaves and flowers. It looks like dried parsley.•Mj can be smoked as a cigarette (joint), in a pipe (bowl) or in a water pipe (bong).•When mj is eaten, the effects are not as predictable because the stomach absorbs THC more slowly.•Consuming large doses of mj may cause hallucinations and severe disorientations.

What is Marijuana?•Tetrahydrocannabinol (THC) is the mind altering ingredient in mj. This chemical compound is responsible for the “high” that users feel.•The typical amount of THC in mj ranges from two to five percent. More THC means more side effects.•In addition to THC, mj contains more than 400 other chemicals which are absorbed into the body. Many of these chemicals can cause cancer.•Mj can be mixed with cocaine, angel dust (PCP) or even embalming fluid (formaldehyde).•Mj often contains mold spores, salmonella, aspergillus bacteria and other foreign organisms that can multiply in the body and cause lung infection.

Marijuana and the bodyThe Respiratory System• Marijuana smoke contains many more

carcinogens than tobacco smoke. It irritates the air passages and throat.

The Lungs• Smoking marijuana kills the cilia in the lungs and

causes excessive build up of phlegm. Regular users often develop a chronic cough which can progress into diseases such as bronchitis, emphysema and lung cancer.

Is it addictive?Addiction: The process of becoming dependent upon a substance or behavior. When the use of a drug becomes a central concern in a person’s life, that person is addicted to the drug- whether the addiction is physical or psychological.

•One-third of all mj users become daily users within 3-5 yrs.•Regular mj use can stunt a person’s emotional growth-the basic ability to deal with anger, fear or even boredom.•Many users become dependent upon mj because they believe that it keeps them from having to face reality.

This mean that mj is considered to have a high potential for abuse and had no commonly accepted medical use.•Legal penalties vary from state to state, but each state has criminal penalties for the use or possession of even small amounts of mj.•Buying or possessing drug paraphernalia is a crime in most states.
