I found a reference to LSD directly killing someone. They injected 320,000 ug intravenously!

To put that in perspective, the "typical" dosis according to wikipedia is ~200ug.

For comparison, if you drink 10L of water, 200 espresso shots, or 600ml of 40% alcohol in one setting, you are likely to die.

Let's assume a psychoactive vodka dose of 10ml and a typical dose of 100ug LSD:

Then the respective vodka dose would be 10ml x (320'000ug / 100ug) = 10ml x 3200 = 32000ml = 32 l

Obviously vodka would be deadly at an amount way below 32l.

(for the unfamiliar, a recreational dose is typically between 70 and 200ug. 200-400 is a heavy dose, and 400+ will leave you incoherent for many hours.)
