     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.

  • Marijuana also elevates heart rate and blood pressure. Some people get red eyes and feel very sleepy or hungry. The drug can also make some people paranoid or cause them to hallucinate.
  • Marijuana is as tough on the lungs as cigarettes — steady smokers suffer coughs, wheezing, and frequent colds.

     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.

  • Nicotine users have an increased risk for lung and heart disease and stroke. Smokers also have bad breath and yellowed teeth. Chewing tobacco users may suffer fromcancers of the mouth and neck.
  • Withdrawal symptoms include anxiety, anger, restlessness, and insomnia.

     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.

  • Though it's part of the depressant family of drugs, it causes some people to be overly excited or aggressive.
  • Rohypnol has received a lot of attention because of its association with date rape. Many teen girls and women report having been raped after having rohypnol slipped into their drinks. The drug also causes "anterograde amnesia." This means it's hard to remember what happened while on the drug, like a blackout. Because of this it can be hard to give important details if a young woman wants to report the rape.
