So I've been filling my cartos with the syringe method, and I was wondering, do I need to dispose of these after I use them? I mean Im not using the medicinally but the vids I watch say that you should dispose of them but I feel like thats just fear mongering to make you buy more.
EDIT: also, any tips / tricks on syringe filling for a noob?
