Someone must have written a comedy around a randomized double-blind cannabis study. The experimental group keeps forgetting if they've taken their meds, taking a month's worth in a week. Researchers forget where they've put the blinding key, so they have everyone take urine tests to see which subjects are in the control group. All of the experimental subjects are too paranoid to show up for a urine test. Researchers resort to putting UV dye on some snacks in order to figure out who's in the experimental group.
