What are the real dangers of our children drinking too young? Addiction expert John Marsden, who likes a drink, makes a professional and personal exploration of our relationship with alcohol.
He undergoes physical and neurological examinations to determine its impact, and finds out why some people will find it much harder than others to resist alcohol.
Even at the age of 14 there may be a way of determining which healthy children will turn into addicts.
John experiments with a designer drug being developed that hopes to replicate all the benefits of alcohol without the dangers. Could this drug replace alcohol in the future?
