Is there a plant that actually makes you fall asleep? I don't mean helps you, I mean like if you smell it or eat it you fall asleep whether you like it or not kind of thing.

I've been wondering for a while if there is a plant that actually makes you fall asleep. I don't mean it helps you, I mean it actually makes you fall asleep whether you like it or not. Whenever I try to search it up it just gives me results that help you fall asleep like chamomile and lavender. Does anyone know of a plant that actually makes you fall asleep or makes you really sleepy? It's just a thought that's been in my head for no appearant reason.
