Everybody sooner or later will try a plant thinking it's 'like marijuana' or other things.
there are plants that i'd consider like 'scam' psychoactive plants,i'll start the list:

Artemisia absinthium: it has beeen confirmed that can't do any effect if it's not been aten at epic dosages.

Nepeta cataria,catnip: i've smoked it and did a tea with it..worthless imho.
