Tests show drug attacks willpower
Scientists at Trinity College Dublin have used sophisticated imaging equipment to show cocaine alters parts of the brain responsible for controlling behaviour and judging risk.
A research team in Trinity College — led by Dr Hugh Garavan — carried out research on dependent cocaine users in the US, involving the administration of pure cocaine in hospitals, followed by a series of computer tasks aimed at measuring impulse control. This was then compared against a control group of non-users.
