Narcotics and Criminal Justice We hear the word Narcotic and most everyone knows this means a mind altering drug of some type but it is what we do not know that can hurt us. The Merriam-Webster online dictionary tells us that a Narcotic is the following: “1a: a drug (as opium or morphine) that in moderate doses dulls the senses, relieves pain, and induces profound sleep but in excessive doses causes stupor, coma, or convulsions b: a drug (as marijuana or LSD) subject to restriction similar to that of addictive narcotics whether physiologically addictive and narcotic or not 2: something that soothes, relieves, or lulls”.

It uses a cup for urine and then has different types of sticks that can test for individual drugs such as
Amphetamines (AMP), Barbiturates (BAR), Benzodiazepines (BNZ), Cocaine (COC), Marijuana (THC), Methamphetamine (MET), Morphine (MOR), PCP (Phencyclidine).GC/MC or Gas Chromatography/mass spectrometry is one of the best ways that labs test verify drugs after preliminary testing for identification as well as the metabolites (a necessary substance in a metabolic process) drawn from provided samples. This machine test different body fluids such as salvia, urine, blood and even sweat to discover what drugs were in a person’s system and has the ability to identify over 400 different types of drugs by using a combination of analytical instruments that are connected to a specifically programmed computer. The gas chromatography typically uses either silica or alumina gel lining in column then a sample of the drug is injected into what is called a “stream of gas”. Once in the stream it is heated by an oven which causes the compounds to separate on the column. As it does this it passes by a detector that sends a signal to be recorded on an “electro-mechanical device”. The next step involves the mass spectrometer where fragments are analyzed according to their molecular weight (N. Coffey). The compounds are then compared to statically data base to determine what compound it is most likely to be. The evidence from the preliminary testing and then the lab
