Here's something I've found out that's pretty interesting:
The black market of prescription medication is anywhere from 5x to 15x cheaper than the legal route of obtaining those same medications, and that's not counting the trip to the doctor's office.
For instance, Lexapro, a common SSRI antidepressant, can cost $60 for 10 20mg pills if you don't have health insurance, or if your prescription isn't covered by your insurance. On alphabay, Lexapro will run you about 70 cents a pill, putting ten pills at $7 as opposed to $60. That's 8.5x cheaper.
Another example (which I also find to be super cool) is a medication called Imitrex. Imitrex is a synthetic tryptamine used in the treatment of migraines. It's an analogue of the naturally-occurring psychoactive molecules Dimethyltryptamine, Bufotenin, and 5-MeO-DMT. How fucking cool is that? Anyways, Imitrex can cost anywhere from $20 per generic 100mg pill, or $37 per "name-brand" 100mg pill.
On the darknet? $2 per 100mg pill. 10x cheaper
Having probably the biggest delta of them all, Strattera, a non-stimulant ADD medication, costs almost $350 for 30 40mg pills. That's almost $12 a pill, or well over $4200 a year! On the darknet they go for $1 per 40mg pill, which is 11.6x cheaper.
Why is this shit so goddamn interesting
