One Standard Drink Size and Calories:
Light beer (4% alcohol): 341 mL (12 oz.) – 1 bottle, approx. 99 calories
Regular beer (5% alcohol): 341 mL (12 oz.) – 1 bottle, approx. 140 calories
Non-alcoholic beer (0.5% alcohol): 350 mL – 1 can, approx. 210 calories
Daiquiri: 207 mL (7 oz.), approx. 260 calories
Piña colada: 133 mL (4.5 oz.), approx. 245 calories
Vodka (40% alcohol): 44 mL (1.5 oz.) – 1 shot, approx. 100 calories
Wine (12% alcohol): 145 mL (5 oz.), approx. 100 calories
Factors Determining Absorption Rate:
Speed of drinking
Rate at which stomach empties
Presence of food and drugs in system
Gender and ethnicity
Absorption Locations:
Oral mucosa: small amount
Stomach: 20%
Upper small intestine: 75%
Metabolism:
Primarily occurs in the liver
Enzymatic conversion: alcohol to acetaldehyde, then to acetate
Individual enzyme variance affects alcohol reaction
Blood Alcohol Concentration (BAC):
Ratio of alcohol in blood relative to body weight
Influencing Factors:
Body weight
Percent body fat
Biological sex
Food intake can slow alcohol absorption
Risks:
Fast drinking increases fatality risk
BAC Zones and Effects:
0.00%: Not impaired
0.05% - 0.07%: Usually impaired
0.08% and above: Always impaired
Example Timeline:
Various weights with respective drink counts over time indicate impairment levels.
Blood Alcohol Concentration (BAC) and Intoxication Stages:
Details effects at different levels of BAC.
Alcohol’s Impact:
Illustrates the correlation between alcohol consumption and risky behaviors.
Low BAC (0.03 to 0.05%): Relaxation and joviality
Increased Bac Effects:
BAC 0.1%: Reduced motor function, sleepiness
BAC 0.2%: Loss of functionality
Severe Risks:
Alcohol poisoning: CNS depression
Symptoms of hangover: headache, shakiness, nausea, fatigue
Potential for increased heart rate and blood pressure.
Drunk Driving Statistics:
Leading criminal cause of death in Canada
Young Canadians (ages 16-25) most affected
Legal Limit:
.08 BAC
.05-.08 BAC: Warning range.
Long-Term Health Consequences:
Impacts on digestive system, cardiovascular system, cancer risk, brain damage, mortality.
Fetal Alcohol Spectrum Disorder (FASD):
No safe level for alcohol during pregnancy.
Consideration:
Moving away from previous beliefs about moderate drinking during pregnancy.
Patterns of Drinking:
76% of Canadians consume alcohol
25% report heavy drinking, especially young adults
Social Burden:
Alcohol misuse leads to productivity losses and healthcare costs.
Weekly Limits:
Women: 10 drinks/week, no more than 2/day
Men: 15 drinks/week, no more than 3/day
Single Occasion Limits:
Women: max 3 drinks; Men: max 4 drinks
Absolute Limits: During driving, heavy machinery, mental health issues, pregnancy, etc.
Risk Levels:
0 drinks = no risk
1-2 drinks/week = likely safe
3-6 drinks/week = cancer risk
7+ drinks/week = increased risk of heart disease/stroke.
Prevalence Across Demographics:
Alcohol use disorder affects all ethnic groups and socio-economic levels.
Criteria for Diagnosis:
Overconsumption, unsuccessful attempts to cut down, time spent obtaining/recovering from alcohol.
Physical and Psychological Issues:
Tolerance development, withdrawal symptoms, hazardous use, continued use despite issues.
Definition:
Reaches BAC .08% or more; for males (5 drinks), females (4 drinks) within 2 hours.
Prevalence:
17% of Canadians in 2020 were heavy drinkers, particularly among those aged 18-49.
Withdrawal Symptoms:
Shaking, sweating, rapid pulse, potential seizures.
Co-occurring Disorders:
Depression, schizophrenia, other substance abuse problems.
Causes:
Genetic influences; environmental factors like household violence.
Treatment Options:
Ranges from self-help to professional treatment programs.
Statistics by Sex and Province:
Rates of exceeding low-risk drinking guidelines for males and females in various provinces.
Support Strategies:
Open and honest communication; eliminate enabling behaviors.
Self-Examination:
Reflect on personal reasons for drinking.
Community Responsibility:
Encourage responsible drinking attitudes; be a responsible host.
