I know that in the U.S. our drugs are put into classes by numbers such as Schedule I, Schedule II, etc. But I've also heard drugs in the U.S. being called a "Class A Substance, Class B Substance, etc." My friend was recently arrested for a few different things and I wanted to know if anyone knew where to find a list of all the drugs scheduled under class letters instead of schedule numbers. I tried searching on Google and just kept coming up with the scheduling numbers but that's not what I'm looking for.

basically the type of drug used. hallucinogen, stimulant, depressant, narcotic and anabolic steroids.

Here we use C#'s, I know the UK and maybe Massachusetts uses letter classes. I think class A might be CI and class B CII...
