One in seven Cambridge students is dealing drugs to help pay their way through university, according to a survey. It found many claim that they have been forced to sell illegal substances to friends to make ends meet as they study. And it revealed nearly two-thirds admitted taking drugs, with cannabis the most popular substance. Cocaine was the most frequently used Class A drug, with a quarter of students saying that they had snorted it at some point. Many claimed the drug – which has halved in price over the past ten years – was more widely used at Cambridge than at any other university they had visited. Alarmingly, 14 per cent of those who have taken banned substances have been admitted to hospital or needed medical attention as a result.
