Idk if this story is true, but it always makes me laugh, so I choose to believe it is
In his personal diaries, Nikolai Bukharin writes, "Joseph [Stalin] came to me one night as I was struggling to finish the final edit of an issue of Pravda. He handed me an ounce of marijuana that reeked of skunk. The smell alone was enough to make me tremble. 'This is a gift from Lysenko and I', he said, and left almost immediately. I smoked that weed and was never the same."
