After injecting approximately 150 mg of amphetamine sulphate dissolved in 4 mL of water in the crook of my right arm (basilic vein), these red marks appeared on my arm.
I felt a slight burning sensation in my arm while injecting. I do not use a tourniquet.
The redness was completely gone within 10 min of injection. Most likely, this was caused by adulterants in the substance.
What is the correct terminology to describe this?
