The lining of the vein can get damaged by the needle, the drug (especially
tablets), injecting too often or too fast, using too much acid, infection
and flushing.
Damage
to the lining of the veincauses clots to form on the inside of the vein.
The
disruption of blood flow causes more clots to form, making the vein
even narrower.
Eventually
the vein blocks, and the clots turn into scar tissue which shrinks and
pulls the sides of the vein together, causing it to collapse.
Collapsed
veins never recover.
Go
slow. Be gentle.
Rotate
sites.
Use
a new sterile needle and syringe every time.
Look
after your veins.
