Oh, here in SPRINGFIELD, OHIO we have a pharmacy that sells half-inch 50 unit insulin syringes to ANYONE without I.D.(most of the time) and 50% of the time you don't even have to sign for them.
HOWEVER,
they reap the benifits, they are happy to help "junkies" (like myself) but they charge a pretty penny...
$10 a bag (10 to a bag)
It is the same way where I live as far as pharmacists/pharmacies goes, for better or for worse. I don't live in a major city, but rather a tri-city area; there are 3 cities which are basically connected, each with about 50-60k people each. Including the in between neighborhoods, there are about 325k people here. And this is in Appalachia, where opiate use is EXTREMELY prevalent. Despite this, there are no exchanges, and almost ALL pharmacists apparently do not believe in harm reduction. There is literally ONE pharmacy in the entire area that will sell rigs to people who are not diabetic, with no questions asked. At every pharmacy that sells them to diabetics, they usually run around $3 for a 10 pack.
But like I said, there is one pharmacy in the area that will sell 10 packs to anyone. They don't keep a list, they don't ask any questions, and they don't hassle you or give you a hard time. Just walk in, ask for what kind of rigs you want, and they are happy to help you out. But unfortunately, they charge $10 for a 10 pack. They are not naive, and I am glad they help people out as far as harm prevention goes, but they definitely take advantage of the fact that NO other pharmacies will sell to those without diabetes.
So I guess I'm glad I can always get clean rigs, but it kinda sucks that they charge so much. But still, better than having to deal with dull, clogged rigs. It certainly makes using them much easier, and does much less damage to my body as far as scars, etc are concerned.
Now I'm not saying I throw away after a single use, but I generally don't use a rig more than 5-10 times. Any more than that, and they start getting too dull for my preferences, and prone to clogging. But back when I did have to worry about keeping a rig working as long as possible, I had a couple ways of combating clogging.
The first, and most important and effective way I have found, is to clean your rigs AS SOON AS you are done with your shot. I have found that 99% of the time, clogging usually occurs from dried blood. I would simply draw up some water in the rig, around half full, then pull the plunger to the end, filling the other half with air. I would then shake it real good, and expel the water. Would usually do this 2-3 times after every use. This seemed to keep my rigs from ever clogging. Using this method, they would usually go dull beyond any practical use long before they started clogging.
But if I did forget to clean it out right after use for whatever reason, usually just a couple seconds of flame on the tip would do the trick. This was followed again by drawing water into it to remove whatever was causing the clogging.
But really, just cleaning your rigs right after use is the best way to avoid clogging. Proactive prevention of clogging really is the best way to deal with it.
