What impact would expect south africa's decision to levy duties on drugs imports from western nations to on the international distribution of drugs to south africa? tools?

The effect that I am expecting would be an expansion in the import cost and furthermore an expansion in the cost of the medication. With the cost increment, the general population in Africa won't be acquiring. By expanding the import cost and costs of medications this at that point diminish the request. By expanding duty's this precludes millions from securing debilitated individuals access to what they require.
