As we know, adolescents are vulnerable to the effects of alcohol In fact, taxi drivers in London have increased hippocampal size Let, us look at the example of the hippocampus, a structure of the forebrain involved in memory and spatial navigation

Overall evaluation Alcoholic beverages are carcinogenic to humans Ethanol in alcoholic beverages is carcinogenic to humans
As a carcinogen, alcohol increases the risk of cancers of the oral cavity and pharynx, oesophagus, stomach, colon, rectum, liver and female breast in a linear dose–response relationship

Relation with cardiovascular disease • The more you drink, the greater the risk of: • Hypertension • Arial fibrillation • Haemorrhagic stroke
Relation with cardiovascular disease • There is a J-shaped-relationship between alcohol and: • Ischaemic heart disease • Ischaemic stroke • Compared with abstainers, light drinkers have reduced risk; beyond the bottom of the the risk increases with a dose-response relationship J
Relation with cardiovascular disease • In young people, alcohol increases the risk of ischaemic events • In old people, the protection tapers off with age
Relation with cardiovascular disease • For the middle aged, the protective effect • Is no different between exclusively beer or wine drinkers • Disappears the more the abstaining comparison group includes ex-drinkers • Disappears when light drinkers report at least one heavy drinking occasion per month
Relation with cardiovascular disease • Most of the protective effect can be achieved by a consumption of 5g alcohol (half a drink) a day • More protection can be achieved by engaging in other healthier behaviours (e.g., healthy diet, more physical activity)

Did you know: • Alcohol damages the adolescent brain?
Did you know: • 25% of male and 15% of female adolescent deaths are due to alcohol?
Did you know: • Amongst us, alcohol is the top cause of ill-health and premature death?
Did you know: • That alcohol in pregnancy increases the risk of early childhood acute myeloid leukaemia nearly three-fold?
Did you know: • That alcohol produces cancer in at least 8 major organs?
Did you know: • Drinking a bottle of wine a day means a 10% chance that your death is due to alcohol?
I do not think people know these facts • Shouldn’t we use every opportunity to inform them?
Alcohol produces cancer • Shouldn’t we use every opportunity to warn people about this?
