Hey there Luana.
I believe that this situation has nothing directly to do with your government but everything to do with the huge pharmaceutical companies and the influence they wield over your government. And the simple question is why are the same drugs produced by the same company available here so much cheeper. For myself my HRT is prescribed and I claim it through my Ontario Health insurance Plan which in turn bills the government. I know that your States do not have such plans in place and I believe that the pharmaceuticals are the reasons why, it's a question of profits.
