What are the common drugs of abuse and how do they work?
Alcohol: Alcohol, while a legal drug, is often abused and habitual use can lead to addiction and significant physical and psychological health problems. Alcohol is rapidly metabolized by the liver into its principle chemical components including carbon dioxide and sugars. Alcohol is within the family of depressant drugs with symptoms including slurred speech, loss of motor coordination and impaired judgment. Alcohol is consumed primarily for its psychotic effects which include a loss of inhibitions and euphoria. Alcohol can only be detected through testing for a relatively short period due to its rapid metabolization and elimination. Generally, detectable levels of alcohol intoxication are gone within 12-18 hours. Consequently all alcohol tests must be performed during or shortly after consumption. Amphetamine: (AMP) Amphetamines are central nervous stimulants whose effects include alertness, wakefulness, increased energy, reduced hunger and an overall feeling of well being. Large dose
