Im looking at getting needles (probably carry just a couple gauges and lengths). Micron wheel filters, again, probably just one or 2 sizes and kind) I don't thin that It would be too practical to sell milligram scales as they are very touchy, ect. But that will be a maybe. I am looking at getting narcan. This will be the most difficult, but I have an idea or two on getting this. alcohol wipes and possibly sterile saline solution. Ill be starting small and adding to it if there is a demand. I think putting together a kit, like x amount of syringes, x amount of micron wheel filters, with wipes, etc. Send me any ideas that you guys have. Ill have to put some thought into this....
