Just let people buy the same stuff people take for prescriptions, at the same prices they would pay if they were uninsured.

If you’re uninsured, a month’s supply of cheap ADHD stimulant meds is like $40, and that’s for somebody taking it daily not recreationally. Fancy patented stuff like Vyvanse costs like 10X more but there you’re paying for timed consistent long-term release, which isn’t exactly a huge concern for recreational use.

“I wanna buy some ritalin”

“Do you have a prescription?”

“No.”

“Can I see some ID?”

“Okay.”

“Okay. That’ll be $40. Since you’ve never taken this before we strongly recommend you take your first hit now and sit in that chair for 40 minutes so we can make sure you don’t OD and die. Fill out this consent form, watch this video, and give me another $40 for this one-time onboarding.”
