  1. Depressants Alex Jessen

  2. Assessment Statements • D.4.1- Describe the effects of depressants • D.4.2-Discuss the social and physiological effects of the use and abuse of ethanol • D.4.3-Describe and explain the techniques used for the detection of ethanol in the breath, the blood, and urine • D.4.4-Describe the synergistic effects of ethanol with other drugs • D.4.5-Identify other commonly used depressants and describe their structures

  3. D.4.1- Describe the effects of depressants • Low to moderate dose: • Calmness • Relief from anxiety • Very relaxed muscles • High dose: • Slurred speech • Altered perception • Sleep induced • Lethal dose: • Respiratory depression • Coma/death

  4. D.4.2-Discuss the social and physiological effects of the use and abuse of ethanol • Ethanol, , is the alcohol present in beer, wine, and hard liquor • Short term effects: • Loss of balance and judgment • Violent behavior • Dehydration • High doses: vomiting, coma, and death • Long term effects: • Dependence known as alcoholism • Liver disease • High blood pressure • Permanent brain damage

  5. D.4.3-Describe and explain the techniques used for the detection of ethanol in the breath, the blood, and urine • Breath: • Breathalyzer • Contains crystals of acidified potassium dichromate (orange) • Changed to Chromium ions (green) as they oxidize the ethanol and ethanoic acid

  6. Gas-liquid Chromatography • Done in a laboratory • Test for blood or urine

  7. D.4.4-Describe the synergistic effects of ethanol with other drugs • Aspirin: • Risk of ulcers • Bleeding of the stomach lining • Other depressants: • Heavy sedation • Coma • Tobacco: • Liver Cancer • Intestine Cancer

  8. D.4.5-Identify other commonly used depressants and describe their structures • Contain: • Two benzene rings • Amide group • Carbon-nitrogen double bond
