I wouldn't think it would be a problem as long as you have proof that you allergic to Naloxone. They might only give it to you a week at a time in the beginning so they can monitor your drug screens to make sure you are not abusing anything else. Have you actually gone in to see the doctors OR just inquired over the phone? You might have better luck going in to talk to someone and stating your case. Be careful buying off the street. It's not worth getting robbed or arrested for something you should be able to obtain legally. Give Dee's link a try. I am suprised you didn't have any luck with suboxone.com or NAABT - those are both good resources.
