Overview
Many people believe marijuana really isn’t that bad. Maybe you’ve heard it can be used as medicine. It seems like a lot of people use marijuana. You’re probably wondering why some states would legalize it if it was really so terrible. But just like alcohol, marijuana can be very dangerous, especially for younger people. This page will help you understand the risks that come with marijuana use and how you can avoid this addictive drug.
What Is Marijuana?
Marijuana, also known as cannabis, is a psychoactive drug that comes from a plant. It can be smoked, vaporized, or eaten. Marijuana contains the chemical THC, which is found in resin produced by the leaves and buds of the cannabis plant. This plant also contains over 500 other chemicals.
Marijuana is an addictive drug, meaning you may not be able to stop once you start. It’s especially addictive to kids and teens. In fact, the risk of developing a marijuana use disorder is greater in those who use marijuana at younger ages. 20% of people who start using marijuana between the ages of 12-17 will develop marijuana use disorder compared to 11% of people between the ages of 18-25
The Risks of Marijuana
You know drugs affect you, but do you know how? Many young people believe that legalizing marijuana means that it’s safe to use, no matter the age. That simply isn’t true. And research tells us that when teens and young adults believe there is little risk in using marijuana, rates of use increase.
The more someone uses marijuana, the worse the effects. The following mental and physical effects should convince you how dangerous marijuana can be and how it can negatively impact a person’s life.
Marijuana use seriously impacts every area of your brain, making it difficult to produce clear thoughts, keep on task, and manage normal situations.
- Memory Problems
- Anxiety and Paranoia
- Difficulty thinking clearly
- Difficulty with problem solving
- Easily distracted
- Coordination problems
- Disturbance in social life
- Inadequate school performance
Statistics show that teens who use marijuana are more likely to quit high school and not get a college degree.
Did you know these risks are dramatically increased when you start using marijuana before you’re 18? Marijuana can have permanent effects on the developing brain when use begins during adolescence. Heavy and regular use only magnifies those effects.

Paranoia & Psychosis
Schizophrenia is a condition where people hallucinate and can be severely paranoid. Marijuana is especially dangerous for youth because the risk of developing schizophrenia increases if marijuana use starts at an earlier age.
Marijuana doesn’t just harm your brain. Did you know that marijuana smoke contains 50 to 70 percent more cancer-causing substances than tobacco smoke does? Smoking marijuana leads to an increased rate of lung infections and illnesses.
Marijuana causes the heart to beat faster and increases your blood pressure immediately after use. Marijuana use could also lead to increased risk of stroke, heart disease, and other vascular diseases.
It can also cause severe nausea and vomiting. Cannabis hyperemesis syndrome (CHS) is a condition caused by long-term marijuana use. People who have CHS experience regular and severe episodes of nausea, vomiting, dehydration and abdominal pain, resulting in frequent visits to the emergency department.

Marijuana Use Disorder
Extensive use of marijuana can lead to marijuana use disorder. When a person uses a lot of marijuana frequently, they are at risk to develop this disorder. That means the person is unable to stop using marijuana even if they want to. This addiction may cause social and health problems, but they simply cannot stop. A person who uses marijuana is much more likely to develop this disorder.
When a person suffers from marijuana use disorder, they are unable to quit even when they try.
They crave marijuana all the time. They take more marijuana than they meant to. They give up activities and hobbies that were once important to them. They withdraw from family and friends. They use marijuana in high-risk and unsafe situations. They suffer from withdrawal symptoms.
That doesn’t sound too great, does it? The best way to keep from getting addicted is to never try marijuana in the first place.

High School Students (9th - 12th grade)
The amount of Johnson County 9th graders using marijuana is less than the state average. From 10th grade to 12th grade, however, the percentage of high schoolers using marijuana increases with each grade, going up to 35% by 12th grade.
Myths vs Facts
Chronic marijuana use leads to addiction. Research indicates that about 9%–or 1 in 11–people that use marijuana will become addicted. That number increases to 17% if someone starts using marijuana in their teen years.
Fact: The THC in marijuana can impair judgment and increase susceptibility to mental problems. It can cause depression and anxiety. If you already have those problems, marijuana can make them worse.
Fact: You know smoking marijuana is bad for you. Being in the same room as others smoking marijuana isn’t great either. Second hand smoke from marijuana contains the same toxins and carcinogens as tobacco.
Fact: Research shows that marijuana use can damage the parts of your brain that control learning and memory. Students who regularly use marijuana are likely to have lower IQ scores and higher dropout rates.
Fact: Studies have shown that the more THC in a person’s system, the lower their driving ability. Marijuana impairs judgment, reaction time, and motor coordination. Plus, the chance of being involved in an accident doubles with marijuana use. Over 20% of fatal car accidents involved a driver impaired by marijuana use.
Some teens think marijuana is safe because it is used for medical purposes. Marijuana prescribed for a medical reason is called “medical marijuana.” Laws for medical marijuana are rapidly changing and vary widely from state to state. There is very limited research that supports the use of medical marijuana in children or teens for most conditions. In most states that allow medical marijuana, the marijuana is unregulated and therefore is not checked for ingredients, purity, strength or safety. There is no evidence that medical marijuana is any safer than other marijuana.
