What is A Supp 2 drug?

Answer 1

You may be thinking of "Schedule II" drugs. These are drugs placed within the Controlled Substances Act (CSA) of 1970.

If this is what you're referring to...it would be a drug with a medical use yet a high potential for abuse and addiction.

Answer 2

According to

http://www.drugdigest.org/DD/Glossary/Glossary/0,5023,86591%7C,00.html

a "Supp" drug is a 'supplemental drug'.

In other words, if you're taking a medication that causes a certain adverse-enough side effect, you will be prescribed a drug to minimize the side-effect, which is called a 'supplemental' drug, so named because your overall health requires you to keep both drugs in supply.

In the case where the supplimental drug also causes a side-effect bad enough for you to need to be taking another drug to minimize those side effects, it's called a 'secondary supplimental' or 'supplimental 2' for short, or 'supp 2' for even shorter notation.

I don't claim to say that what the above contributor might not also be true, but, this is one way that 'supp 2' is used, in the Pharmaceutical community.
