As a general rule of thumb, most of the times you find something that grows in nature that causes hallucinations, but it isn't something you've heard that people take to hallucinate, it's because taking enough of it to trip will make you a lot sicker than it's worth or is generally regarded as a terrible "trip" or can fuck with your brain in the long term. For example; nutmeg is also a hallucinogen. Commonly causing palpations of the heart and an impending feeling of doom with delusions of grandeur and possible mental breakdowns. A tablespoon of nutmeg might just ruin your week, so to speak. But it tastes nice as a spice so it's in most houses and grocery stores because pretty much no one ever wants to use it as a fun time drug.
