A $150 1/4 Oz? I can get a full Oz for that, if not cheaper, at home! $200 an oz for stuff I'd put up against any "high grade" or "medical" they're growing on the island. Prices are dropping because of legalization. There's a lot of legally grown decent domestic product being illegally dumped on the streets, lowering prices.
The legal market is too tightly regulated and more importantly, too small so prices remain artificially inflated. Imagine what would happen if every liquor store only sold a couple of the most expensive top shelf brands? The average "Joe" in the legal states are not getting their stash at a dispensary. Dispensaries are very much "boutique operations" at this point.
I corrected my friend when he said "ah man I got ripped off!". I reminded him he got what he agreed to pay for so nobody ripped him off. He agreed on the price. He didn't have to buy it.
I got the impression they didn't enjoy their trip and won't be back. Some people just don't know how to deal with hustling...which is their own fault, but it's sad because here's another group that won't likely return.
