Sir: Most of the suicides that occur in Pakistan do so with the usage of sleeping pills. There are lots of chemists in Pakistan that sell these tranquillisers without seeing any prescription. Neither their licences have been cancelled nor has any warning been given to them. Although the drug control authority has received several complaints about illegal activities like selling expired medicines and sedatives without proper prescription, no action has been taken yet. I request all the drug control authorities and inspectors to take serious action against this crime. AMNA SULTANA Karachi
