These days, drugs can be found everywhere, and it may seem like everyone's doing them. Lots of people are tempted by the excitement or escape that drugs seem to offer.
But learning the facts about drugs can help you see the risks of chasing this excitement or escape. Here's what you need to know.
Addictiveness: Teens who use it can become psychologically dependent upon it to feel good, deal with life, or handle stress.
Marijuana
The most widely used illegal drug in the United States, marijuana resembles green, brown, or gray dried parsley with stems or seeds. A stronger form of marijuana called hashish (hash) looks like brown or black cakes or balls. Marijuana is often called a gateway drug because frequent use can lead to the use of stronger drugs.
Street Names: pot, weed, blunts, chronic, grass, reefer, herb, ganja
How It's Used: Marijuana is usually smoked — rolled in papers like a cigarette (joints), or in hollowed-out cigars (blunts), pipes (bowls), or water pipes (bongs). Some people mix it into foods or brew it as a tea.
Effects & Dangers:
• Marijuana can affect mood and coordination. Users may experience mood swings that range from stimulated or happy to drowsy or depressed.
Addictiveness: Teens who use marijuana can become psychologically dependent upon it to feel good, deal with life, or handle stress. In addition, their bodies may demand more and more marijuana to achieve the same kind of high experienced in the beginning.
Methamphetamine
Methamphetamine is a powerful stimulant.
Street Names: crank, meth, speed, crystal, chalk, fire, glass, crypto, ice
How It's Used: It can be swallowed, snorted, injected, or smoked.
Effects & Dangers:
• Users feel a euphoric rush from methamphetamine, particularly if it is smoked or shot up. But they can develop tolerance quickly — and will use more meth for longer periods of time, resulting in sleeplessness, paranoia, and hallucinations.
• Users
sometimes have intense delusions such as believing that there
are insects crawling under their skin.
• Prolonged use may result in violent, aggressive
behavior, psychosis, and brain damage.
• The
chemicals used to make methamphetamine can also be dangerous
to both people and the environment.
Addictiveness: Methamphetamine is highly addictive.
Nicotine
Nicotine is a highly addictive stimulant found in tobacco. This drug is quickly absorbed into the bloodstream when smoked.
How It's Used: Nicotine is typically smoked in cigarettes or cigars. Some people put a pinch of tobacco (called chewing or smokeless tobacco) into their mouths and absorb nicotine through the lining of their mouths.
Effects & Dangers:
• Physical effects include rapid heartbeat, increased blood pressure, shortness of breath, and a greater likelihood ofcolds and flu.
Addictiveness: Nicotine is as addictive as heroin or cocaine, which makes it extremely difficult to quit. Those who start smoking before the age of 21 have the hardest time breaking the habit.
Rohypnol
Rohypnol (pronounced: ro-hip-nol) is a low-cost, increasingly popular drug. Because it often comes in presealed bubble packs, many teens think that the drug is safe.
Street Names: roofies, roach, forget-me pill, date rape drug
How It's Used: This drug is swallowed, sometimes with alcohol or other drugs.
Effects & Dangers:
• Rohypnol
is a prescription antianxiety medication that is 10 times
more powerful than Valium.
It can cause the blood pressure to drop, as well as cause memory loss, drowsiness, dizziness, and an upset stomach.
