Although many people smoke because they believe cigarettes calm their nerves, smoking releases epinephrine, a hormone which creates physiological stress in the smoker, rather than relaxation. The use of tobacco is addictive. Most users develop tolerance for nicotine and need greater amounts to produce a desired effect. Smokers become physically and psychologically dependent and will suffer withdrawal symptoms including: changes in body temperature, heart rate, digestion, muscle tone, and appetite. Psychological symptoms include: irritability, anxiety, sleep disturbances, nervousness, headaches, fatigue, nausea, and cravings for tobacco that can last days, weeks, months, years, or an entire lifetime.

Risks associated with smoking cigarettes:

  • diminished or extinguished sense of smell and taste
  • frequent colds
  • smoker's cough
  • gastric ulcers
  • chronic bronchitis
  • increase in heart rate and blood pressure
  • premature and more abundant face wrinkles
  • emphysema
  • heart disease
  • stroke
  • cancer of the mouth, larynx, pharynx, esophagus, lungs, pancreas, cervix, uterus, and bladder

Cigarette smoking is perhaps the most devastating preventable cause of disease and premature death.

Smoking is particularly dangerous for teens because their bodies are still developing and changing and the 4,000 chemicals (including 200 known poisons) in cigarette smoke can adversely affect this process.

Cigarettes are highly addictive. One-third of young people who are just "experimenting" end up being addicted by the time they are 20.

Ecstasy is an illegal synthetic, or designer, drug. Designer drugs mimic an already illegal drug by slightly altering the chemical composition. Ecstasy is also called MDMA, which stands for methylenedioxymethamphetamine. The amount of MDMA needed to get "high" is close to the toxic dose. Ecstasy is similar to methamphetamine and MDA, which is another designer drug in it's chemistry; therefore it may have similar affects to other amphetamines. Ecstasy acts as a stimulant to the central nervous system. Ecstasy can be found in a capsule or pill form, of various colors. It may also be in powder form. Ecstasy is commonly used at "rave" party settings. "Raves" are all night parties known for their dance music and drug experimentation. Other names for ecstasy are wonder drug and XTC.

HERE ARE THE STRAIGHT FACTS ABOUT... Cocaine and Crack Cocaine

Cocaine is a white powder that comes from the leaves of the South American coca plant. Cocaine is either "snorted" through the nasal passages or injected intravenously. Cocaine belongs to a class of drugs known as stimulants, which tend to give a temporary illusion of limitless power and energy that leave the user feeling depressed, edgy, and craving more. Crack is a smokable form of cocaine that has been chemically altered. Cocaine and crack are highly addictive. This addiction can erode physical and mental health and can become so strong that these drugs dominate all aspects of an addict's life.

Physical risks associated with using any amount of cocaine and crack

Psychological risks

Increases in blood pressure, heart rate, breathing rate, and body temperature.

Heart attacks, strokes, and respiratory failure.

Hepatitis or AIDS through shared needles.

Brain seizures.

Reduction of the body's ability to resist and combat infection.

Violent, erratic, or paranoid behavior.

Hallucinations and "coke bugs"--a sensation of imaginary insects crawling over the skin.

Confusion, anxiety and depression, loss of interest in food or sex.

"Cocaine psychosis"--losing touch with reality, loss of interest in friends, family, sports, hobbies, and other activities.

Some users spend hundred or thousands of dollars on cocaine and crack each week and will do anything to support their habit. Many turn to drug selling, prostitution, or other crimes.

Cocaine and crack use has been a contributing factor in a number of drownings, car crashes, falls, burns, and suicides.

Cocaine and crack addicts often become unable to function sexually.

Even first time users may experience seizures or heart attacks, which can be fatal.

Hallucinogenic drugs are substances that distort the perception of objective reality. The most well-known hallucinogens include phencyclidine, otherwise known as PCP, angel dust, or loveboat; lysergic acid diethylamide, commonly known as LSD or acid; mescaline and peyote; and psilocybin, or "magic" mushrooms. Under the influence of hallucinogens, the senses of direction, distance, and time become disoriented. These drugs can produce unpredictable, erratic, and violent behavior in users that sometimes leads to serious injuries and death. The effect of hallucinogens can last for 12 hours.

LSD produces tolerance, so that users who take the drug repeatedly must take higher and higher doses in order to achieve the same state of intoxication. This is extremely dangerous, given the unpredictability of the drug, and can result in increased risk of convulsions, coma, heart and lung failure, and even death.
