The History of Kamtschatka
Krasheninnikov's 1764 English translation describes fly-agaric (Amanita muscaria) intoxication in Kamchatka: its effects, use by the Koryak, and the practice of drinking an intoxicated person's urine to prolong inebriation. He covers dose-dependent effects and behavioral consequences including murderous impulses.
