Marijuana

What is it?

Marijuana is made from the dried leaves and flowers of the Cannabis Sativa plant. The active ingredient in marijuana is tetrahydrocannabinol or THC. Marijuana may be green, brown or grayish in color. Marijuana can be inhaled through smoking with the use of rolled papers, a pipe, in a blunt or using a vaporizer. Marijuana is a Schedule 1 Controlled Substance. Some states have legalized marijuana for medical and/or recreational use. Marijuana is illegal in Iowa.

What does it do?

There is significant evidence that shows adverse and permanent changes in the brain when marijuana is used during the developing years in humans. 

Side effects: 

Within a few minutes after inhaling marijuana smoke, a person’s heart rate speeds up, the bronchial passages (the pipes that let air in and out of your lungs) relax and become enlarged, and blood vessels in the eyes expand, making the eyes look red. While these and other effects seem harmless, they can take a toll on the body.

  • Increased heart rate is common and may increase by 20 to 50 beats per minute or, in some cases, even double. This effect can be greater if other drugs are taken with marijuana. The increased heart rate forces the heart to work extra hard to keep up.
  • Similar to the effects of regular cigarettes, marijuana smoke irritates the lungs and can cause a chronic cough, often resulting in respiratory (lung and chest) problems.
  • The risk of experiencing depression and anxiety is increased with marijuana use.
  • Marijuana use during pregnancy is linked to lower birth weight and a higher risk for many developmental issues.
