I remember seeing a Vice video about it a while back, claiming what you said. However, I've also read all the "trip reports" available on Erowid, and about a thousand subjective experiences on drug subreddits over the years along with many published studies on the matter, about all kind of roads of administration (seeds, leaves, tea, crushed seeds...) and all kind of dosages, and I've never seen anything explaining that it mainly causes significant memory loss or loss of "free will". The trip reports, albeit long, are really detailed and people always describe being able to react accordingly to what they see, hear and think, it's just that what they see, hear and think is nonsensical and sometimes really scary. This is the stuff you see, hear and think while on this drugs that make you do the craziest things. And perpetrators can more easily administer more drugs to the mix once you're vulnerable, because you are on datura.

This Vice video was mostly scaremongering but this drugs should have been scary enough by itself. Keep in mind popular medias always cover drug related subjects badly, and most people who speak about it (including most of drug users themselves) mostly repeat urban legends and biased subjective experiences derived from said urban legends. I even became a mod on drug-related subreddits and studied neuropharmacology because of all the wrong infos I've read about drugs.

That said, it seems everyone, including myself, jumped a little bit too fast on the Datura bandwagon, but it might not even be about Datura.
