Alcohol and alcoholism

Physical effects of alcohol use

Biopsychosocial effects of alcohol abuse


Physical effects of alcohol use l.jpg

Physical effects of alcohol use

  • Cardiovascular benefits from 1 glass of wine per day: The French paradox?

  • The benefits disappear at the equivalent of three glasses per day.

  • The same benefit can be obtained from grape juice, but it takes six glasses per day: the beneficial ingredient in wine may be flavinoids rather than alcohol


Is the french paradox really a paradox l.jpg

Is the French paradox really a paradox?

  • Cardiovascular disease is a cumulative, delayed consequence of many factors, including diet.

  • Prior to the 1960s, the French diet was much lower in saturated fat than the American diet.

  • American “control group” studies are correlational.

  • Participants are self-assigned to groups.

Approaches to alcohol use l.jpg

Approaches to alcohol use

  • Total abstinence

  • Cultural uniformity

    • Israel & Italy vs. Ireland & Finland

  • Parental introduction vs. parental prohibition (Mitic, 1990)

  • Is it possible to teach controlled drinking in a culture of excess?

  • Would the FDA approve alcohol today?

Treatments for alcoholism l.jpg

Treatments for alcoholism

  • Controlled drinking

  • Total abstinence

  • Comorbidity problems


Pharmacological support l.jpg

Pharmacological support

  • Antabuse

  • Apomorphine for conditioned aversion

    • Not popular currently

  • Antipsychotics for hallucinations: Dangerous

  • Antidepressants for comorbid depression

  • Benzodiazepines for withdrawal

  • Naltrexone for craving

  • Ondansetron, a 5-HT3 antagonist, for early-onset alcoholism

  • Acamprosate, a glutamate agonist at NMDA receptors and a GABA-A agonist


Abused inhalants huffing l.jpg

Abused Inhalants: huffing

  • Gases: Nitrous oxide and halothane

    • Anaesthetics, propellant for whipped cream

  • Volatile liquids

    • Ether and chloroform

    • Petroleum distillates

      • Gasoline, paint thinners, toluene, butane, propane

      • Solvents: Benzene, correction fluid, markers

    • Aerosol propellants: cooking spray, stain protectors, paint (chroming, from popularity of silver and gold spray paint)

    • Nitrites: Butyl, cyclohexyl (deodorizer), propyl and amyl (poppers, snappers). Nitrites are used mainly by adults, in an attempt to enhance sexual sensations.

  • Abused inhalants cause irregular heart rhythms, and are sometimes lethal.
