A former government minister has called for all drugs, including heroin and cocaine, to be legally available. Do you agree with this approach?

Bob Ainsworth, who was responsible for the issue under Tony Blair, says successive governments have failed in their approach and the current policy has left the drugs trade in the hands of criminal gangs.

Mr Ainsworth has called for a strict system of legal regulation under which different drugs would either be prescribed by doctors or sold under licence.

Does the government's drug strategy need changing? Have you struggled with drug addiction? How can criminal drug gangs be stopped?
