In the 22nd century, where these drugs have been produced in the quantity of millions- academic level chemists should already know the fundamental effects of each drug through rigorous studying. It definetly makes sense for them to understand what each drug that they can produce does, the impact and varying levels according to quality.
Anybody can make a catalogue of drugs and their effects through experimentation, it probably won't be nearly as accurate as what advanced chemists should already know. And I'd argue if I was doing this as a non chemist character, I would icly be investing U.E into my chemistry skill even abit as the experimentation goes on as you're learning about the field.
It does not take away RP for them to know this.
And what you're saying is possible definetly to get a good approximation, but I imagine there's much more obsufucation then just taking a look at our character sheet. Especially if we're talking about the effects of differing levels of quality.
Furthermore, i'd argue that most of the roleplay in regards to this comes from researching the effects of a combination of different drugs, to which there are countless. And there's still lots of things to players to figure out oocly anyways that I didn't include in my suggestion (duration, side effects, downsides etc).
