I am very much aware that in Texas, there is no law regarding syringe sales. That is confirmed by the link that was posted.
Let me highlight a different part of the very same article in red...
What Laws and Regulations Affect Pharmacy Sales?
A number of laws, regulations, and pharmacy practice policies effectively restrict
pharmacy sales of sterile syringes to IDUs.(5)
For example, 47 states plus the
District of Columbia and the Virgin Islands have drug paraphernalia laws that
criminalize the sale and possession of syringes if it is known that they may be used
to inject illegal drugs. Eight states and the Virgin Islands also have laws requiring
individuals to have a valid medical prescription to purchase syringes. (See the
related fact sheet, State and Local Policies Regarding IDUs' Access to Sterile
Syringes.
In addition, 23 states have pharmacy regulations or practice guidelines that restrict
pharmacists from selling sterile syringes to IDUs or that impose additional
requirements on customers who wish to purchase syringes. Some pharmacy chains
and individually-owned pharmacies also have policies that restrict over-the-counter
sales of syringes.(6)
Many individual pharmacists are also reluctant to sell sterile syringes to IDUs even
where such sales are legal. (7,8,9) This reluctance stems from negative feelings
toward IDUs, disapproval of injection drug use, concerns about unsafe disposal of
used syringes, and concerns about safety and crime. Many pharmacists follow
procedures that make it more difficult for IDUs to buy syringes, such as asking for
photo identification, requiring the name and address of the customer, asking for
confirmation of diabetic status, asking the customer to explain why they need to buy
the syringes, or selling only to individuals who are known to the pharmacist.(7,8)
For the portion in green, I implore you to look up the literature which this sentence references. It is a free article:
Journal of Acquired Immune Deficiency Syndromes and Human Retrovirology 1998;18 (Suppl 1):S60-S70
On page S63, "Pharmacists retain considerable discretion in deciding whether they will sell injection equipment and to whom they will sell. This leads to wide variations in the willingness of pharmacists to sell syringes. Biases toward, for example, racial minorities, young people, or the homeless can limit the opportunities for IDUs to purchase syringes at pharmacies."
Any reference to pill mills, is again, irrelevant to the discussion. We are talking about the OTC sale of syringes, not the filling of controlled medications where the validity of a prescription is in question.
I will cede to you that under Texas law, you DO have the right to restrict access to syringes, just as I have the right to sell them to those who ask for them.
I have no way of positively knowing whether someone is an IDU, short of them shooting up inside my pharmacy. My own
opinion is that I am applying my own biases/prejudices by restricting access to those who I don't positively know are an IDU.
Please don't take this as a character assassination. I do think it is good to have a debate about a gray area in which both sides are able to state their beliefs and supporting information.
