In countries with universal healthcare, there is an argument that government should take a more active role in dissuading the use of substances that cause social harm and harm to the body and result in long term expenditure for public health. The detail is in how far government should go, e.g. educational initiatives, regulation, or prohibition, etc.
I’m actually sympathetic to rural pharmacies having increased financial viability issues (although the Rural Pharmacy Maintenance Allowance will apparently be doubled in the next budget), but the Pharmacy Guild I think has run a misleading campaign, such as referring to widespread shortages. The Pharmacy Guild has a lot of power in this country, but I’m glad most people seem to support increased dispensing.
