The British Medical Association's Scottish council published a five-point action plan on Sept 7 in which it said retailers should have to apply for a licence to sell tobacco to prevent under-age sales.
But ACS chief executive James Lowman said such a system would be "disproportionate and costly" and
lead to more regulation and bureacracy for retailers.
He said: "A new system, with all the costs attached, should not be introduced when the existing penalties are not being used to their full extent."
The BMA Scotland also suggested that cigarettes should not be placed at the point of sale, or sold in packets of 10. It
called for tobacco vending machines to be banned and for more investment to be made in education.
BMA Scotland member Dr Andrew Buist said
the BMA thought more would need to be done to enforce the age limit.
