A recent study commissioned by Brighton and Hove city council recommended the opening of drug consumption rooms, places where people could inject drugs under medical supervision without fear of prosecution.
The aim is to lower the number of drug-related deaths in the city, a problem Brighton suffers with particularly, and reduce the amount of drug-taking on the street and the associated problems that it causes.
Critics however have suggested the policy would risk condoning illegal behaviour, will enable people to continue a poor lifestyle and places too much emphasis on harm reduction at the expense of care for users.
