These Regulations further amend the National Health Service (General Medical and Pharmaceutical Services) (Scotland) Regulations 1974 (“the principal Regulations”) which provide the arrangements to be made by Health Boards for the provision in their areas of general medical services and pharmaceutical services. Regulation 2 amends the principal Regulations to include in the description of pharmaceutical services participation by chemists in hypodermic needle exchange services. Such services permit chemists to supply, free of charge, to drug misusers new hypodermic needles and syringes, to accept used hypodermic needles and syringes for safe disposal, and permit a chemist, once he has received appropriate training, to provide counselling to drug misusers.
