The social drug of choice in Western culture is alcohol. Yet it is estimated to kill 100,000 a year in the UK alone. The Independent Scientific Committee on Drugs puts it near the top of the list of dangerous drugs while others like ecstasy, LSD and cannabis come much lower down. Should we wean ourselves off alcohol or even ban it, and instead promote other less harmful but currently illegal alternatives? Or do we think the benefits of alcohol are just too great to take this seriously?
