Alcohol – General facts Alcohol is a drug Alcohol enters the blood stream and
alters how your body works Alcohol has a direct influence on the
function of your brain and how it responds to different stimuli
Alcohol has varying effects depending on how much you consume
Alcohol - General facts cont’d
Alcohol usually makes you feel- relaxed- uninhibited (you are more likely to do something you would never
normally do when under the influence of alcohol)
Alcohol Alcohol is broken down by
- the liver Alcohol is broken down at the rate of
- 1 unit per hour after alcohol consumption has stopped
Acceptable units of alcohol per week- Female 14units- Male 21 units(these figures have been altered since this course was written)
How to work out the units of alcohol
Work out your alcohol units for yourself with this handy sum:
No. of = Strength (%) x volume (ml) units 1000
E.g. Pint of Stella 5.2 (%) x 568 (ml) ÷ 1000 = 2.95 units
Measuring alcohol level of body Low tech method breathalyser
High tech method Digital alcometer
Short term effects of alcohol Longer/slower reaction
time- you will take longer to brake in a car therefore are more likely to have an
accident

Reaction timeReaction time is time taken to respond to a stimulus. Measured using:Calibrated ruler (low tech)Electronic timer (high tech)Affected by:Drugs Excitementalcohol
Used as an indicator of health. Slower reaction times caused by:
Diabetes Nerve disorder Brain disorder Arterial disease
Alcohol and reaction time Under the influence of alcohol you
have slower reaction times
You break down alcohol at 1 unit per hour after you stop drinking
Think about the scenario on the next slide
Scenario You binged on alcohol at the weekend
and consumed 12 units before you stopped drinking at 2am.
Would you be safe (i.e. have your
reaction times recovered enough) to drive to work at 8am the same morning?
1 in 4 accidents are caused by drink driving
Alcohol and pregnancy
If a mother consumes alcohol during pregnancy the baby also consumes the alcohol – it passes across the placenta from mothers blood to baby’s blood
Alcoholic expectant mothers can have a baby who has foetal alcohol syndrome – low birth weight, developmental problems and low IQ
Quiz What are the short term effects of
alcohol? What are the long term effects of
alcohol? Name a low and high tech method of
measuring alcohol content of the body. What effect does alcohol have on your
reaction time? What effect does alcohol have on an
unborn child?
