The heat is on…The resignation of the Advisory Council of Misuse of Drugs’ adviser, Dr Polly Taylor (veterinary medicine expert whose position on within the Council is required by law), has quit just hours before their advice was due on the banning of mephedrone in the UK this morning.  This, which could lead to the delay on the board’s advice to the Government.  A Liberal Democrat spokesman has said that Home Secretary Alan Johnson would have to wait until the Council was “properly constituted” before announcing the ban.  The Home Office has said it would not speculate on any delay on the ban and is expected to announce its decision later in the day.  Is it getting hot in here?
