4 Categories of Psychoactive Drugs • Based on their effects on the mind and body, psychoactive drugs are classified into 4 major categories 1. Stimulants 2. Depressants 3. Narcotics 4. Hallucinogens
Some Other Drugs • There are also 3 other types of drugs that have effects similar to the 4 major ones 5. Cannabis 6. Inhalants 7. Designer Drugs • Lastly, we will also be discussing steroids, which is not a psychoactive drug, but is often abused
1. Stimulants • Drugs (nickname) • Legal - nicotine and caffeine • Illegal • amphetamine (speed, uppers) • methamphetamine (ice, glass, crystal meth) • cocaine (coke, snow, crack) • Physical Effects – stimulate or speed up nerve activity (increased energy and heart rate, loss of appetite, difficulty sleeping)
Stimulants continued… • Psychological Effects – euphoria, increased alertness, depression, paranoia, hallucinations • Effects of Overdose – extreme nervousness, hallucinations, paranoia, heart and lung failure, coma death • Withdrawal Symptoms – lack of interest in normal activities, fatigue, irritability, depression, mental confusion
Amphetamines • Makes users feel more energetic and alert, and euphoric (state of happiness) • One side effect is a loss of appetite, so doctors used to prescribe this drug for short periods of time to help people lose weight • In large amounts, amphetamines can make people feel paranoid
Methamphetamine • Produces euphoria that lasts 12 to 24 hours (during this time, user cannot sleep and has no appetite) • Was also used legally for weight loss • Users become paranoid, aggressive, and violent • Can cause permanent damage to the brain and body
Cocaine • White powder made from leaves of the South American coca plant • Sometimes used as anesthesia in nose and throat surgery • Highly addictive and causes serious physical and psychological problems • Cocaine’s effects are felt quickly, but do not last very long
2. Depressants • Drugs (nicknames) • Legal – alcohol • Illegal • barbiturates (downers) • tranquilizers • methaqualone (ludes, sopers) • Physical Effects – depresses or slow down nerve activity (decreased heart rate and breathing, sleepiness, poor coordination, blurred vision, slow reaction)

Barbiturates • Strong depressants that are prescribed to relax people or help them sleep • After addicted, people cannot fall asleep without the use of barbiturates • Barbiturates cause mental confusion, so users take accidental overdose • When combined with alcohol, it can cause the user to stop breathing
Tranquilizers • People who suffer from anxiety may be treated medically with tranquilizers • Also dangerous when combined with alcohol and causes hundreds of fatal drug overdoses every year
Methaqualone • Produces sudden rush of euphoria • Physical and psychological dependence develops very quickly • Side effects include headaches, nosebleeds, dizziness, and diarrhea • High risk of fatal overdose when combined with alcohol
3. Narcotics • Drugs (nickname) • codeine (school boy) • opium (blue velvet, back stuff) • morphine (white stuff, morf) • heroin (horse, smack, junk) • Physical Effects – strong painkiller that produces a relaxed state (pain relief, decreased heart rate and breathing, nausea, vomiting, constipation, slurred speech, poor coordination)

Opium • Stronger narcotic that may be prescribed to relieve pain or control diarrhea • Produces an initial rush of euphoria followed by a prolonged dreamy state • Highly addictive and causes severe withdrawal symptoms
Morphine • One of the strongest known painkillers • Extremely addictive, so it is strictly limited for medical use (post-surgery or cancer patients) • Abused for its euphoric effects with severed withdrawal symptoms
Heroin • White powder made from morphine, but is more potent because it acts quicker • Prohibited from medical use in US because it is extremely addictive • Most widely abused narcotic in the US • Heroin dulls the senses for hours, but addicts must take several doses each day to avoid withdrawal symptoms • High risk of hepatitis and AIDS

Cannabis continued… • Psychological Effects – mild euphoria, relaxed inhibition, difficulty concentrating, impaired memory • Effects of Overdose – fatigue, paranoia, panic, mental confusion, distorted perceptions resembling mental illness • Withdrawal Symptoms – irritability, restlessness, difficulty sleeping
Marijuana • Most widely used illegal drug in the US because many users think it is harmless • Made from dried and shredded leaves and flowers of the cannabis plant • Usually smoked and its effects felt within minutes and may last for hours • Similar health effects of tobacco, but worse because it contains more dangerous chemicals
Marijuana continued… • Marijuana interferes with the mental development of teenagers and young adults (impairs memory and concentration with difficulty learning) • THC is the active ingredient in marijuana and has been legal since 1986 for chemotherapy patients • Some people have been working to convince the government to reclassify marijuana as Category 2 instead of 1 so that it can be used for medical purposes
Hashish • Oily liquid taken from the cannabis plant that has more intense effects than marijuana because its more concentrated • More expensive than marijuana, so it is less widely used in the US

7. Designer Drug • Designer drugs are new chemical combinations that are created to imitate the effects of controlled drugs • The most common types of designer drugs imitate stimulants, narcotics, and hallucinogens • For example, ecstasy imitates the effects of amphetamines and LSD • Can cause more damage for they are more powerful and less predictable
8. Steroids • Steroids are laboratory-made drugs that function like the male hormone testosterone to increase muscle mass • Steroids may be prescribed for young people who are not growing normally • Steroids are not considered psychoactive drugs, but have stimulant-like effects for some users because it makes them feel good about building muscle
Steroids continued • Physical Effects – increased muscle mass and calcium in bones • Psychological Effects – stimulant-like high, increased energy and aggressiveness, possibly violent • Long-term Risks – mental disorders, liver damage, infertility, acne, baldness, reduced sperm production for men, increased facial hair for women
