The proposed Trans Pacific Partnership is likely to push up the price of medicines, stop some Australians from taking their medicines and make it harder to restrict the sale of tobacco and alcohol, a comprehensive review of the deal between Australia and 11 other nations including the US and Japan has found.

The so-called health impact statement, compiled by the Centre for Health Equity Training Research and Evaluation at the University of NSW relies on leaked texts of draft chapters of the agreement Australia is preparing to seal within weeks.

Although its stated aim is to bring down trade barriers and allow mutual recognition of standards, many of its provisions deal with medicines and make it difficult for member countries to move against foreign-owned corporations.

The health impact statement follows Commonwealth guidelines for such statements in place for more than a decade. Although such statements are not required for new projects in the same way as are environmental impact statements, they are an accepted procedure for establishing the impact of new proposals on health.
