(speed) are more potent forms of amphetamines that have few medically approved uses.
What is one drink?
-1/2 ounce pure alcohol -12 oz beer -10 oz wine cooler -4-5 oz wine -1.5 oz distilled alcohol
Patterns of Tobacco Use
-20.6% of the adult population in the United States are smokers -The decline of smoking since 1965 is largely because of public health campaigns about the hazards of smoking -Although smoking in the United States has declined, the rate of decline has slowed since 1990
Alcohol-related deaths in college students
-5,000 alcohol-related deaths occur each year among those aged 18 to 24. -1,600 are killed each year due to alcohol-related injuries. -75% of these deaths are due to alcohol-related car crashes and 25% to other alcohol-related causes, such as drowning, falls, gunshots, and alcohol/drug poisoning.
Contraception- IUD
-A small device inserted into uterus where it remains in place -Inhibits the ability of sperm to reach and fertilize egg -May thin the uterine lining and prevent implantation -Active ingredient in the IUD is either copper or progestin. -Among the safest, most effective, and least expensive reversible contraceptives available
Who drinks alcohol?
-About 65% of American adults drink at least occasionally -35% of the adult U.S. population are abstainers -Of the two-thirds who do consume alcohol, 28% are at-risk drinkers -Low-risk drinkers are men who drink no more than 14 drinks per week or women who drink no more than 7 drinks per week -"One drink" is defined by the NIAAA as 0.5 ounce (or 15 grams) of alcohol
Alcohol and College Students
-Alcohol abuse often appears or accelerates during college years. -Alcohol is the most abused drug among college students. -Moderate drinkers who do not abuse alcohol cite a variety of reasons for drinking, such as social ease or stress relief; they are not goal-oriented drinkers (i.e., drinking to get drunk). -Heavy drinkers who abuse alcohol usually drink for escapist and goal-oriented reasons.
How the body processes alcohol
-Alcohol is absorbed into the bloodstream from the stomach and intestinal tract. -The blood transports alcohol to the "detoxification center" of the body—the liver. -Alcohol is absorbed into the bloodstream more quickly than it can be broken down by the liver, and the excess alcohol stays in the blood. -Eating food, which keeps alcohol in the stomach longer, allows more alcohol to be broken down before entering the bloodstream.
Effects on behavior and safety
-Automobile accidents: 31% of all fatal motor vehicle crashes in 2012 were alcohol-related. -Alcohol impairs pilots' ability to function. -Hangover effect may impair pilot performance for up to 8 hours after drinking.

-Battery powered device -Provides inhaled doses of nicotine by heating a chemical solution into a vapor -Provides a flavor and physical sensation similar to that of inhaled tobacco smoke -Produce no tar, burning, real smoke, or air pollution -Contains tobacco specific organic compounds, nicotine, and other potential carcinogens
Induced Abortion
-Caused by the taking of certain drugs or via surgical procedure -Method used will depend on stage of pregnancy.
Tobacco and Prevention
-Children's social environment is the most important determinant of whether they will smoke. -Prevention programs now target seventh and eighth graders, reaching children before most start smoking. -Focus on helping young people develop skills to identify and resist social influences to smoke, such as advertising and peer pressure
Immune and Reproductive Systems
-Chronic drinking impairs the immune system, predisposing the drinker to infectious diseases. -Men: lower than normal testosterone levels, shrinking testicles, impotence, and loss of sex drive (libido) -Women: irregular menstrual periods or no periods, higher rate of premature menopause -Alcohol consumption during pregnancy can have a devastating effect on the fetus.
Cocaine
-Cocaine is a powerful stimulant derived from the leaves of the coca bush. -Crack is a rock crystal form of cocaine. -It has some medical uses, particularly as an anesthetic. -Highly addictive -Causes serious health problems including damage to the nasal passages, lungs, and respiratory tract, cardiovascular problems, and severe psychotic reactions, including paranoia.
Medical Abortion
-Conducted between weeks 7-9 of pregnancy -Involves use of medications that cause changes in the pregnant woman's body so that it cannot sustain the pregnancy, followed by expulsion of the contents of the uterus
Drug use and Abuse
-Drugs are nonfood chemicals that alter the way a person thinks, feels, functions, or behaves. -Drugs are commonly taken for medicinal purposes. -Psychoactive drugs are taken for their mind-altering and mood-altering effects. -Inappropriate drug use contributes to crime, unemployment, and family violence and dissolution.
Cigars
-Have more tobacco and nicotine per unit than cigarettes do, take longer to smoke, and generate more smoke and more harmful combustion products than cigarettes do -Tobacco mix used in cigars makes it easier for cigar smoke to be absorbed through mucous membranes of the oral cavity -Nicotine takes longer to reach the brain, results in a less intense but longer lasting effect -Cigar smoking exposes the oral mucosa to large amounts of carcinogens resulting in a higher risk of oral cancer
Psychoactive Drugs: effects on mind and body
-Interact with nerve cells in the brain and alter activity of chemical transmitters -Many commonly abused drugs affect specific brain regions called reward centers. -Produce euphoria, an intense feeling of well-being (a "high") Psychoactive drugs reach the brain through the bloodstream. -Undergo detoxification mostly in the liver -Some drugs are stored in body fat for weeks and detoxified slowly over time. -Overdose—when the body is unable to eliminate excessive amounts of a drug before reaching toxic levels
