I wonder if Ergotamine could be an Amine from Ergot. Should probably be abbreviated EA in that case.
I'm not (just) being judgmental here: volunteering harm reduction at festivals, the number 1 problem we had was that users had no idea what they had put into their bodies.
Actual chemists, no doubt, don't use any of this terminology since chemical reactions don't produce the desired results if you're vague about what you put into them.
If someone asked me what the typical salt was I'd say table salt
Lsd is also exclusively sold as tartrate
HCl + NaOH -> HOH (water) + NaCl
But if you mix a different acid and a different base, you'll get a different salt, for example if you mix sulphuric acid and calcium hydroxide, you get calcium sulfate:
H2SO4 + Ca(OH)2 -> 2(HOH) + CaSO4
Calcium sulfate is just a different salt.
