chromatography/mass spectrometry is used to test hair and urine samples of possible drug abusers or job applicants‚ and it is the best method for the testing of drug use. Gas chromatography and mass spectrometry are two different methods for identifying chemical substances‚ and the two instruments have be coupled together to perform a highly complementary analytical function. The gas chromatograph and the mass spectrometer have theories behind how their techniques work‚ and specific forensic applications for their

For instance‚ it is believed that drugs have exacerbated the already weak status of mental health in the United States in which some individuals suffering from mental illness administer illicit substances such as heroin or cocaine in an attempt to self-medicate.

Response to question 1: 1) Correctional substance abuse in the State’s prisons is one of the biggest problems that the criminal justice system has to be very keen with. This is especially to make sure that inmates who have this problem are first and foremost recognized and provided with the needed treatment services (Karberg & James‚ n.d).

too. Chemical reactions are also very hard to reverse. One example of chemical change is when sugar is combined with sulfuric acid. We can tell it is a chemical change because heat and bubbles are produced‚ and carbon was separated from the other substances. On the other hand‚ physical reaction only does macroscopic changes to the matter‚ for example‚ altering the shape‚ and painting the matter. There is not rearrangement of atoms in a physical change. Only a few properties change during a physical

Within this current experiment I will asses the pharmaceutical preparation of Panacetin‚ by using it ’s solubility along with other organic molecules. We know that Panacetin is made up of sucrose‚ aspirin and some other unknown substance. We know the substance has to be Phenacetin or Acetanilide. To help solidify our reasoning‚ we need a % recovery

The Impact of Drugs on Society Drugs have effects on society in many different ways. The negative consequences of drug abuse affect not only individuals who abuse drugs but also their families and friends‚ various businesses‚ and government resources. The ONDCP (2202) discusses the effects of drug abuse. “Although many of these affects cannot be quantified‚ ONDCP reported that in 2002‚ the economic cost of drug abuse to the United States was $180.9 billion.”(www.usdoj.gov ) Devastating
