Drug Analysis

Drug Analysis/Lab
Drugs are a factor in many crimes, as they can lead to violence or in the case of an overdose be the cause of death of a victim. The Mexican government estimates that 90% of violent crime around the border is drug related. In order to investigate crimes involving drug use, investigators use various indicators to test for the presence of drugs. In our lab, we used indicators to test for the presence of LSD, Cocaine, or Meth.






Drugs Used in Lab Investigation

File:CocaineHydrochloridePowder.jpgCocaine: This drug is derived from the coca plant and is very widespread worldwide, despite the cultivation, sale, and consumption being illegal in nearly every country. Cocaine increases alertness, feelings of well-being, energy and euphoria. Anxiety, paranoia and restlessness are also frequent symptoms of cocaine use. Tremors, convulsions and increased body temperature can occur when cocaine is ingested in large doses.

File:AciD.jpgLSD: This semi-synthetic psychedelic drug is usually taken by applying to blotters such as the one shown on the right and taking as shown in the picture. Effects of LSD include pupil dilation, change in appetite, wakefulness, "tripping" (a distorted sense of atmosphere and environment that varies every time the drug is consumed), increase in creativity, paranoia and panic attacks, permanent change in perspective on life, and widely varied spiritual experiences. LSD is less dangerous than many other drugs, as no deaths have been documented as a result of LSD.

Methamphetamine: Also known as "meth", this highly addictive drug increases alertness, concentration, energy, and induces euphoria. Other symptoms include anorexia, hyperactivity, paranoia, irritability, hallucinations, and a feeling of invincibility. Withdrawal symptoms and relapse are common due to the highly addictive nature of the drug. Methamphetamine is approved by the FDA for the treatment of extreme obesity and ADHD.

Notable Case Involving Drugs:
In 2009, singer Michael Jackson died of Cardiac Arrest after overdosing on several prescription sedatives. His personal physician, Conrad Murray, was present when he died. Murray was later sentenced to four years in prison after being convicted of involuntary manslaughter
