I see brains everywhere at the moment – on posters, in jars, on a shelf… We all have one, but do we all take good care of it?

A study at the University of Cambridge has found that long-term cocaine users have older brains compared with non-drug users.

Images of participants’ brains showed that those aged 30–40 who had taken cocaine for about 10 years had brains similar to people aged over 60. The researchers also found that cocaine users’ brains shrink almost twice as fast as the brains of non-drug users.
