You answered the question and I see you're being intentionally obtuse.
A diabetic cannot "wait" for sugar identically to the same way a cardiac patient cannot "wait" for nitroglycerin tablets if they feel heart fluctuations. A concert promoter shouldn't be permitted to refuse entry to someone with pills in their pocket because they "think" it might be a recreational/illegal drug.

All right, one vote against private property rights. I don't see what is being obtuse about defending those.
