Local and National Policymakers, Pharmacies, Doctors, Individuals
Currently unused medicine waste outside the healthcare setting is mixed with general household waste. Pouring chemical and pharmaceutical wastes down the drain can impair the functioning of biological sewage treatment plants or septic tanks. These can end up polluting the eco system and water sources.
As it requires special methods of disposal it should be up to pharmacies to have a collection bin for unused medicine and take responsibility for appropriate disposal.
