"What ever your feelings are on marijuana, remember that it is still against the law."
Marijuana is a green, brown, or gray mixture of dried, shredded leaves, stems, seeds, and flowers of the hemp plant. Common names are pot, weed, grass or joint.
The main chemical ingredient in marijuana that creates mind-altering is THC (delta-9-tetrahydrocannabinol).

LONG TERM EFFECTS
It's hard to know for sure whether regular marijuana use causes cancer. BUT it is known that marijuana contains some of the same, and sometimes even more, of the cancer-causing chemicals found in tobacco smoke. Studies show that someone who smokes five joints per week may be taking as many cancer-causing chemicals as someone who smokes a full pack of cigarettes every day.
Lungs and airways:
People who smoke marijuana often develop the same kinds of breathing problems that cigarette smokers have: coughing and wheezing. They tend to have more chest colds than nonusers. They are also at greater risk of getting lung infections like pneumonia.
Animal studies have found that THC can damage the cells and tissues in the body that help protect people from disease. When the immune cells are weakened, you are more likely to get sick.
SOMEONE ON POT:
Seem dizzy and have trouble walking, seem silly and giggly for no reasons, have very red bloodshot eyes, and have a hard time remembering things that just happened.
