Study Notes
Alcohol Effects
- Alcohol affects the brain, causing loss of coordination, poor judgment, distorted vision, memory loss, and blackouts.
- It increases heart rate, raises blood pressure, and can alter heart rhythm. The heart's size may also increase.
- Alcohol affects the stomach, potentially leading to weight gain, vomiting, ulcers, and cancer.
- It can damage the liver, causing cirrhosis, hepatitis, and liver cancer.
- Alcohol also affects the reproductive system, potentially increasing painful periods and heavy flow, and increasing the risk of sexual assault.
- Alcohol affects mental function; low BAC can impact information processing and memory, while higher BAC levels can result in personality changes, depression, coma, and death
- Alcohol damages the liver by creating harmful substances during the breakdown process, which can cause serious liver disease.
Intoxication and BAC
- Intoxication refers to being under the influence of alcohol or drugs.
- BAC (Blood Alcohol Concentration) measures blood alcohol intoxication.
- BAC levels are categorized; different levels lead to different effects: from relaxed feelings to aggression to unconsciousness and death (levels 0.01 to 0.41).
- A BAC of 0.1 indicates 0.1grams of alcohol per 100ml of blood.
Drug Use
- People use drugs for pleasure, popularity, peer pressure, curiosity, and sometimes to treat existing conditions, or because of addiction.
- Not all drugs are dangerous; some, like antibiotics and vaccines, are beneficial.
- Drugs are chemicals that alter bodily functions by entering the bloodstream and affecting different parts of the body, sometimes altering senses and pain perception and affecting brain chemistry.
Types of Drugs
- Uppers: Stimulants that increase energy, alertness, and endurance, but can lead to dependence. Examples include nicotine, caffeine, and cocaine.
- Downers: Depressants that slow down bodily processes, potentially causing memory loss, brain damage, and other negative effects. Examples include alcohol, tranquilizers, pain killers, narcotics, inhalants.
- All Arounders: Substances that can act as both stimulants and depressants, impacting reality perception and mental processes. An example is LSD.
Alcohol's Advantages and Disadvantages
- Alcohol production creates employment opportunities in various sectors.
- It generates significant income for the state through taxes.
- Alcohol abuse can be costly due to illnesses, premature deaths, accidents (like drunk driving), reduced productivity, and higher insurance costs.
- Alcohol impacts the criminal justice system due to associated behaviours and incidents.
- Drinking and driving presents a considerable risk to both the driver and others on the road.
