What exactly is marijuana?

The risks and effects of marijuana may surprise you

The science:
Marijuana, or Cannibas sativa, is a mind-altering psychoactive drug. Of the 400 chemicals found in the plant, THC affects the brain the most.1
The short-term effects:
Marijuana disrupts learning, memory and problem solving, and can cause distorted perception, loss of motor coordination, increased heart rate and anxiety.1
The long-term effects:
Marijuana affects the brain's reward system, which can lead to addiction — especially for those who start in their teens.1
The result:
Marijuana increases the risk of chronic cough, bronchitis, anxiety and schizophrenia (schiz·o·phre·ni·a) in the vulnerable individuals.1

Marijuana vs cigarettes.

Your lungs don't really know the difference between marijuana smoke and tobacco smoke.

The science:
Smoke from marijuana contains many of the same toxins, irritants and carcinogens as tobacco smoke.5
Marijuana smoke tends to be inhaled more deeply, which leads to a greater exposure to tar.5
Secondhand smoke:
Secondhand marijuana smoke contains many of the same toxins and carcinogens found in directly inhaled marijuana smoke — in similar amounts if not more.5
Lung health:
Marijuana smokers can develop many of the same respiratory problems as tobacco smokers, such as phlegm production, wheezing and acute bronchitis.5

Graduating is a better high.

Teens who use marijuana daily are 60% more likely to drop out of school. 6

90% of addictions start in the teen years.1
Heavy use of marijuana in teen years and adulthood shows a permanent drop in IQ.7
Teens who are heavy marijuana users have significantly more memory and attention problems.6
Marijuana and alcohol:
Teens don't typically use alcohol or weed, but both. When combined, it's easier to accidently drink to dangerously high blood alcohol levels.1
Teen marijuana users are 18 times more likely to become dependent on the drug.6
More drugs:
Teen marijuana users are 8 times more likely to use other illicit drugs later in life.6
Teen marijuana users are 7 times more likely to attempt suicide.6
