Physiological Factors
Motor vehicle crashes are the leading cause of death for all people from 6 to 33 years of age.
The easiest way to group drugs and alcohol is by their similarities.
Classifications and a few more common examples are as follows: central nervous system depressants (alcohol, sleeping pills, tranquilizers) , central nervous system stimulants (nicotine, cocaine, amphetamines), opioids (opium, codeine, heroin) hallucinogens (LSD, mushrooms, morning glory seeds, mescaline, pcp), cannabinols (marijuana, hashish), inhalants (industrial solvents or aerosols, gasoline, chloroform, airplane glue, metallic plants, nitrous oxide(laughing gas), anabolic steroids (synthetic testosterone), and anti-psychotic drugs (Haldol, thorazine).
There are several ways for a drug or alcohol to enter into the body. The most common forms are by drinking, smoking, snorting, injecting, inhaling, or ingesting.
Another important factor is the strength of a particular substance. For alcohol, its strength is measured by proof. Proof is double the alcoholic percentage of a beverage. For example, bourbon that is 90 proof is 45% alcohol.
The alcohol content of common beverages is beer (3-6%), wine (11-20%), liqueurs (25-35%) and liquor (40-50%).
How the body absorbs alcohol and other drugs is unique for each drug or classification of drugs.
The upper part of the intestine has a large surface that aids in the absorption of alcohol into the bloodstream. The sooner alcohol passes into the large intestine; the faster it can be absorbed.
Things that can alter this process are carbonated beverages ( causes the pyloric valve to open and as a result the drink is absorbed faster into the bloodstream) and food ( slows the rate of movement into the small intestine).
From the intestine, alcohol is passed into the bloodstream. Capillaries carry the alcohol into the bloodstream (the
