Brain on Drugs
It doesn’t just help you think. It helps you smell, hear, feel, move, breathe, write, see, solve problems, remember things and make decisions. It’s a finely tuned machine. It works faster than the fastest computer in the world.
Curious How Your Brain Works?
IT’S MADE UP OF THREE MAIN PARTS:
What Do Drugs Do?
Marijuana affects a person’s judgment and can impair driving ability. Regular users might see their grades start to slip in school or become addicted.
Alcohol can damage or even kill neurons and alter brain development. Someone who’s had too much alcohol has problems making safe decisions. These are the parts of the brain impacted when someone drinks:
control impulsive behavior
controls movement, balance and complex motor functions
controls judgment, behavior, and emotion
RETICULAR ACTIVATING SYSTEM
controls sleeping and waking
controls heartbeats, breathing and other functions
Nicotine is one of more than 4,000 chemicals found in the smoke from tobacco products. Cigarette smoking accounts for about 90% of lung cancer cases in the U.S.When you smoke, nicotine enters the blood stream and reaches the brain within ten to twenty seconds. It’s a hard addiction to beat because it changes your brain.
Brain Lobes & Functions
A lot of your body parts come in pairs, like your lungs, your eyes and your arms. Your cerebrum also comes in two parts called cerebral hemispheres. Each hemisphere is divided into four parts called lobes. Check out the different names for your four lobes and what each one helps you do.
What’s A Stroke?
A stroke happens when the blood your body carries to your brain gets blocked. Your brain can’t get the oxygen it needs and brain cells die. If a grown up is having a stroke, they might seem confused or have a hard time walking or talking. You can help. Call 911 and get help right away.
How Drugs Hurt Your Brain
Drugs are chemicals. They get in the way of how a healthy brain works. They also cause dramatic, and often permanent, changes in your brain. It’s worse for teenagers because the teenage brain is still developing. The human brain isn’t fully developed until around age 25. Until then, important changes are still taking place.
