Substance D 

1. Substance D is a fictional addictive amphetamine-like psychoactive drug, also known as "Slow Death", "Death" and "D", that is depicted in Philip K. Dick's novel "A Scanner Darkly". It's derived from the fictional flower "Mors ontologica".

2. By extension, Substance D can refer to amphetamine (speed).

"What he sold me as 'candy' actually turned out to be 'Substance D'."

This is a more subtle way to refer to amphetamine in a conversation if you don't want to attract too much attention.

Substance abuse disorder 

New clinical/medical term for a person's drug abuse issues

Substance abuse disorder should be abbreviated as sad, where sad is a noun. I don't suffer from sad.
