In my Psychology book in one chapter it talked about the alcohol impairment and how it can then create bad judgment. Because alcohol acts to depress the reticular activating system, several things occur. The altering mechanism is depressed such that a person does not become aware of potentially hazardous or dangerous situations that the sensory functions detect. The sensory functions themselves are deteriorated and may not be supplying complete or correct information to the brain. A person's motor of functions is impaired; yet, because of alcohol's depressant effect that person will feel less inhibited and more self confident about themselves.
Benzodiazepine drugs are commonly used to treat stress, anxiety and high blood pressure. They work by blocking receptors that are usually activated by adrenaline and noradrenalin, meaning that the body is less able to produce extreme and unhealthy sympathetic nervous system responses. Antipsychotic drugs, which are often used to treat schizophrenia, work by reducing the amounts of dopamine at synapses in certain areas of the brain. Drug treatments have been found to be effective in treating many illnesses, and in many
People who usually take Crystal Meth seek the pleasure from the chemical reaction in the brain and a hyper effect on the body systems. People who use Crystal Meth will experience hyper activity and won’t be able to properly sleep and will become lazy. People who take Crystal Meth appear normal, but for many years of taking the drug, the hidden effects build up. Methamphetamine addiction is very damaging to the body and mind. Bad temper and social difficulties are obvious effects.
Lesher says, “Addiction is a brain disease expressed in the form of compulsive behavior.” As with most chronic diseases, addiction should also be treated with multiple recurring treatments since the brain chemistry of addicts often causes them to relapse into drug use. Lesher makes his case that addiction is a brain disease by stating that addicts cannot quit taking drugs on their own because they require medical treatment like most ill patients. The authors final opinion on addiction is that initial drug use is present due to the voluntary behavior of the addict and while it does not absolve the user of their responsibility as it was their fault, once they have developed an addiction, their brain has chemically changed so much that they can not will themselves to quit and must be treated as though they have a medical disease. NO: Alva Noe states that addiction is not a disease of the brain. First, he points that not all addictions are chemical substances and there are many activities that can be addictive to people.
They receive the drug L-Dopa to increase levels of dopamine. If too much L-Dopa is given to Parkinson patients then it has been shown to trigger schizophrenic tendencies. In addition to this the drug chlorpromazine is given to schizophrenics to reduce symptoms. The drug works by binding to D2 receptors and reduce dopamine. The drug is effective.
It also controls emotion; being intoxicated threatens the normal function of this. Alcohol is a depressant, which means it slows down activity. People mistake alcohol as a ‘pick me up’ because when first drinking it, it makes you feel more outgoing rather then reserved, but as they continue to drink
To Change or Not A long debated issue in the United States is the age at which one can drink. As many youth feel, the drinking age should be lowered. On the contrary, the drinking age should stay right where it is or even be raised. Alcohol is a drug that is potentially addictive. Alcohol intoxicates the brain, leaving you feeling disoriented and slowing your reflexes.
Phenylalanine also disrupts amino acid metabolism, hormonal equilibrium, and nerve functions. Aspartic acid is believed to function as an excitatory neurotransmitter in the central nervous system (CNS). Methanol gets converted to formate, it is either excreted or it gets accumulated in the body to form formaldehyde, diketopiperazine (a carcinogen), and other potent toxic products.

Methamphetamine, like other drugs, is able to short-circuit the survival system by artificially stimulating pleasure areas in your brain. As this happens, it leads to increase confidence in meth, and less confidence in normal life routines. Usually when this occurs the addict will be more interested in meth related activities, meth related people, and meth related environments. Withdrawals of Meth Use: Fact or Fiction? Much to contrary belief meth users do suffer from withdraws as well as any other drug addict would.
Although the intention was good prohibition actually negatively affected the populations’ health because they turned to hard liquor instead of beer. While the supply of alcohol drastically decreased the demand remained the same. Due to the ban on importing or manufacturing of alcoholic beverages in the U.S, it became more difficult to get beverages containing lower amounts of alcohol (e.g. Beer and wine) while getting hard liquor became easier because it was easier to manufacture and smuggle across borders into the country. The higher alcohol content in hard liquor was more effective for getting drunk yet it also took its toll on the population’s health.
