Some states don't, since it's not abusable. In some states it's just Humalog and other fast-acting insulin that requires a prescription. Same with syringes.
One guy had the audacity to tell me (after a litany of physical complaints) that, well, he might as well see a doctor since it's being offered for free and he's not having to look for a job right now.
That's actually a kind of legitimate request. If he is showing symptoms that may be related to the contaminated water, he should be seen. Maybe it's just that he thinks he is borderline and would not want to see a doctor under normal circumstances if he had to take off from work, but since he has nothing better to do, there's no reason for him not to go.
Actually, the guy who wanted medical care because it's free & he's not having to work wanted meds for an "old sciatic nerve" problem and wanted free medicine for his heartburn because he's having to buy TUMs and Rolaids. Nevermind he has no bills and was given a debit card from the Red Cross.
