tasks, and improves the capacity for work. Improves performance and endurance during

prolonged, exhaustive exercise Enhances short-term, high-intensity athletic

performance. Improves concentration, reduces fatigue, and sharpens

alertness.

Caffeine and Its EffectsHealth Effects

A few cups of coffee/day is safe.

Potential Benefits: lower risk for type 2

diabetes & cardiovascular disease;

protect against Alzheimer’s;

reduce the likelihood of gallstones,

Parkinson’s disease, liver cirrhosis, and colon cancer.

High Dosage Effects Dependence Anxiety Insomnia Rapid breathing Upset stomach and

• Generic DrugsHave the same active ingredients as brand-name prescriptions, but their fillers and binders, which can affect the absorption of a drug, may be different.

• Buying Drugs On-lineHealth and legal risks

Prescription Stimulants

Abuse of stimulants prescribed for attention deficit/hyperactivity disorder (ADHD).

Most students who have tried stimulants do not feel that the drugs had a positive effect on their academic performance in the long run.

Prescription Drug Abuse on Campus

Prescription Stimulants

Prescription Painkillers

Reasons for Use: Legitimate goal Acceptability Self-diagnosed ADHD Academic strain Perceived harmlessness

Understanding Substance Use Disorders

AddictionA behavioral pattern characterized by compulsion, loss of control, and continued repetition of a behavior or activity in spite of adverse consequences.

Psychological DependenceThe emotional or mental attachment to the use of a drug.

Physical DependenceThe physiological attachment to, and need for, a drug.

Understanding Substance Use Disorders

IntoxicationMaladaptive behavioral, psychological, and physiologic changes that occur as a result of substance abuse.

WithdrawalDevelopment of symptoms that cause significant psychological and physical distress when an individual reduces or stops drug use.

PolyabuseThe misuse or abuse of more than one drug.

What Causes Drug Dependence and Abuse?

The Psychology of Vulnerability Difficulty controlling impulses, a lack of values that may

constrain drug use, low self-esteem, feelings of powerlessness, denial, and depression or anxiety.

Early Influences Lower socioeconomic backgrounds, family instability, a

lack of realistic, rewarding alternatives and role models, and increased hopelessness.

The Biology of Dependence Dopamine

Dopamine Levels for Cocaine

Drugs and Driving Alcohol affects perception, coordination, and judgment.

Marijuana affects a wide range of driving skills. Slowed thinking & reflexes e.g. brake quickly Ability to “track” or stay in lane through curves Maintain speed & proper distance between cars

4-6 hrs after smoking a single marijuana (long after the “high” is gone)

Sedatives, sedative-hypnotics, and-anti anxiety agents slow reaction time.

Amphetamines, after repeated use, impair coordination.

Hallucinogens distort judgment.

dreamy type of self-absorption, and some impairment in thinking and communicating.

Euphoria peaks within a half hour and usually lasts about three hours.

Risks Brain – acute toxic psychosis, panic attacks,

delusions, paranoia, depression, uncontrollable aggressiveness.

Lungs – pulmonary infections, bronchitis, inflammation, pre-cancerous abnormalities.

1 joint = 4X tar in cigarette – lung exposed to 4X toxins

Heart – Increase heart attack risk Pregnancy

Withdrawal Potential for marijuana withdrawal syndrome

characterized by insomnia, restlessness, loss of appetite, and irritability.

CannabisMarijuana and Hashish

Club Drugs (Designer Drugs)Ecstasy

The Facts Ecstasy is the common street name for

methylene-dioxymethamphetamine (MDMA). Has both stimulant and mildly hallucinogenic

properties.

Common Characteristics of Ecstasy Users More likely to use marijuana, binge drink,

spend more time socializing and less time studying, have multiple sexual partners, smoke cigarettes, rate parties as more important than academics, and view religion as less important.

Risks Psychological difficulties such as confusion,

depression, and sleep problems. Physical symptoms such as involuntary teeth

clenching, nausea, blurred vision, and rapid eye movement.

Club Drugs (Designer Drugs)GHB/GBL

The Facts GHB (Gamma hydroxybutyrate) stimulates the

release of human growth hormone, but has no known effects on muscle growth.

How Users Feel Smaller doses induce euphoria and enhance sex

due to a rise in dopamine in the brain. Larger doses can cause individuals to pass out and

possibly fall into a coma.

Club DrugsThe Risks of GHB/GBL

Side Effects Nausea, amnesia, hallucinations, decreased heart rate,

convulsions, and sometimes blackouts/coma.

Long Term Side Effects Withdrawal reaction including rapid heartbeat, tremor,

insomnia, anxiety, and occasionally hallucinations that last a few days to a week.

The danger is greatest when GHB is mixed with alcohol or opiates.

Club DrugsKetamine (K)

The Facts Ketamine is an anesthetic used by veterinarians. K blocks chemical messengers in the brain that carry

sensory input leading to hallucinations.

Side Effects Low doses: impaired attention and memory, anxiety,

agitation, paranoia, and vomiting High doses: K can cause delirium, amnesia, impaired

motor function, high blood pressure, depression, and potentially fatal respiratory problems.

Other Common Club DrugsNitrites

The Facts Clear, amber-colored liquids Used recreationally for a high

feeling, a slowed sense of time, a carefree sense of well-being, and intensified sexual experience.

Side Effects Stroke, heart attack, and a

disfiguring skin condition.

StimulantsAmphetamines & Methamphetamine

The Facts Amphetamines trigger the release of epinephrine

(adrenaline) which stimulates the central nervous system. Methamphetamine is a powerful addictive stimulant. Meth remains in the central nervous system and the body,

producing prolonged stimulant effects.

How Users Feel Amphetamines produce a state of hyper-alertness and

energy. Meth produces long-lasting toxic effects, including

psychosis, violence, seizures, and cardiovascular abnormalities.

StimulantsAmphetamines & Methamphetamine

Potential Side Effects Bingeing and crashing. Feelings of grandiosity, anxiety,

tension, anger, agitation, paranoia, and impaired judgment.

Long Term Side Effects Malnutrition, skin disorders,

ulcers, insomnia, depression, vitamin deficiencies, sexual dysfunction, impaired concentration or memory, and, in some cases, brain damage.

Stimulants Cocaine

Cocaine is a white crystalline powder extracted from the leaves of the South American coca plant.

Routes of Administration Sniffed/Snorted Injected intravenously (speedballing) Smoked (freebasing/crack)How Users Feel Cocaine stimulates the central nervous system

producing feelings of soaring well-being and boundless energy.

After a brief period of euphoria, users slump into depression.

Risks Cocaine dependence is an easy habit to acquire. Can cause blood vessels in the brain to clamp shut and

can trigger a stroke, bleeding in the brain, and potentially fatal brain seizures.

Withdrawal Depression Fatigue Vivid and disturbing dreams Excessive/too little sleep
