How Alcohol Affects the Central Nervous System Alcohol can affect several parts of the brain, but in general, alcohol contracts brain tissue and depresses the central nervous system. When alcohol reaches the brain, it interferes with communication between nerve cells, by interacting with the receptors on some cells. The alcohol suppresses excitatory nerve pathway activity and increases inhibitory nerve pathway activity. Among other actions, alcohol enhances the effects of the inhibitory neurotransmitter GABA. Enhancing an inhibitor has the effect of making a person sluggish.
In “Science, Law, and the search for Truth in the Courtroom: Lessons from Daubert v. Merrell Dow”, Bertin and Henifin (1994) argue that science and law have different ways of pursuing ‘truth’ and they question who should be taking burden of this uncertain state. Mukherjee et al. (2001) and many other researchers question the risk of Vioxx, which was mainly for osteoarthritis relief, ever since it was introduced in the U.S. pharmaceutical market in 1999 (Wadman Meredith, p.899). Merck & Co. conducted an experiment on safety test of Vioxx, known as the VIGOR, before introducing it to the market and the company did hide the fact that there was a chance of harmful side effects associated with the drug (Mayer Theodore, p.1068). However due to actual risk of Vioxx, Merck & Co. voluntarily withdrew the drug from the market in 2004 (Wolsing Jennifer, p.214).
On August 14, 2007, Mattel recalled over 18 million products because it was possible that they could pose a danger to children due to the use of strong magnets that may detach. Strong small magnets could be dangerous to the children if two or more were ingested, attracting each other in the intestines and causing damage The California attorney general and Los Angeles city attorney said they would file a lawsuit today against Mattel Inc., Toys R Us Inc. and 18 other companies, accusing them of making or selling products that contain "unlawful quantities of lead." In November 19, 2007, Lifsher, M. and Goldman, A, writers of the Los Angeles Times wrote in the article titled Lead in toys sparks lawsuit. Mattel, the lead defendant in the lawsuit, said it welcomed the attorney general's involvement and added that it would be helpful for the entire toy industry. "Mattel expected this development and believes that the attorney general's assumption of this case will be beneficial to all parties," a spokeswoman for the El Segundo company said in a statement.
The use of methamphetamine is associated with long-term biochemical and structural effects on the brain and significantly changes how the brain functions. The excessive production of dopamine causes neuropathological changes in the brain and has a neurotoxic effect on the brain cells that store dopamine and serotonin. These changes include decreases in the levels of dopamine transporters as well as decreases in the density of serotonin transporters in various parts of the brain. Studies have demonstrated that daily use of methamphetamine results in increased cell death in the brain, which would have a negative effect on prefrontal cortex functioning. Changes in the activity of the dopamine system are associated with reduced motor skills and impaired verbal learning.
Effects of Drugs and Chemicals on the Brain and Body Ashley Schreij General Psychology 1030 – F01 Bob Zimmerman March 17, 2013 Effects of Drugs and Chemicals on the Brain and Body Drug abuse is something many people are familiar with. Different drugs affect each person and their mind and body differently.

There are many drugs out there that are addicting and hazardous, but I am going to address some of the more known ones: 1. Alcohol 2.
Milgram devised his psychological study to answer the popular question at that particular time: "Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices? "[3] The experiments have been repeated many times in the following years with consistent results within differing societies, although not with the same percentages around the globe. [4] The experiments were also controversial and considered by some scientists to be unethical and physically or psychologically abusive. Psychologist Diana Baumrind considered the experiment "harmful because it may cause permanent psychological damage and cause people to be less trusting in the future.

Heroin Addiction Treatment Options 1 Can Heroin Addiction be treated? Alternative Treatment Modalities for Heroin Dependence. Maritza Padilla Psychology – 230-1241 Professor B. Harrington November 3, 2012 Heroin Addiction Treatment Options 2 Heroin is a powerful narcotic derived from morphine, which is obtained from the opium poppy.
