No this is not for getting high.
I'm from India, healthcare is super cheap here (although mediocre in most places). I was absolutely flabbergasted when I found out that similar treatments and drugs are often a couple orders of magnitude more expensive in the west, particularly in USA, for seemingly no reason at all.
The government here (in India) intervenes and doesn't let pharma jack up drug prices 'just because' and the fact that they still make and sell the same stuff at the same old low prices means that they're already making a profit. So again it's got to be orders of magnitude worse in countries where pharma industry runs free.
I don't have much experience with dark net markets, I've looked around but that's all. So, what's the scene like? Is this a thing? Legal drugs, just cheaper on the dark net?
Every drug everywhere when compared to buying the US
