I mean, I've gotten drugs from sketchier people. And if we're talking about stimulants, that's almost an advertising point. "So good, it got Elon pulling up floorboards and crashing servers!" is a decent testament to how strong it is.
Plus, if this was a serious conversation, the first thing I would do would be to test for purity and contaminants. Test kits are relatively cheap, and even if you're open to getting baby powder spiked with bath salts in place of cocaine, it's better to know what you're getting into. Test your drugs, people!
