I'm a long term (used to be "ex") IV drug user, and by that I mean everything water soluble has gone in my veins. However, I have a current problem from a binge of IV tianeptine and O-dsmt... I have harded my 2 main veins, beyond what I've experienced before, and I'm wondering if they are still "working" and just surrounded with scare tissue ( I not only reused rigs, but was IV'ing 2-3cc's of Tianeptine solution most recently)? I have other smaller veins but when using something requiring so much liquid, It's very hard for me to hit w/out missing, a full 3cc's... But I cannot tell if it's more from reusing the rigs AND the fact that Tia solution (water,alcohol,pg,tia) is terrible for veins, or if it's primarily one or the other. Each elbow vein I use, feels like a ligament rather than a vein, for reference. You'd think I would take this as "stop shooting up", but just in case, I'm wondering if I can still use these veins, and just need to use fresh rigs to get through the scar tissue (if thats what it is) or if they are no longer functioning veins. Hope this makes sense. Any help would be appreciated. Thx.
