Didin't he almost drank himself to death? I believe he had cirrhosis.Beethoven was a genius, did he smoke weed? Idk i mean maybe someone more informed can enlighten me, but i love beethoven and I dont think he needed any drugs at all, period.
Europeans didn't really smoke weed at the time, it was a pretty rare practice. Although smoking hash started getting popular in the 1800s IIRC.
Many health remedies contained cannabis extracts but it wasn't really seen as a drug (by today's definition).
