Coleridge was a known opium user and wrote under the influence.
Well, he is one of my favorite poets! It’s fine with me if he chewed grass with the cows ;0)
There are poets who write while in a non-drug induced trance. I’ve done it! Dolly Parton, wrote that she writes her music while staying in her mountain home -when there she fasts, and one gets a tad euphoric while fasting for long periods of time.
