It's similar, but notice that so far no one has voted for Ayahuasca as being most likely to cause a bad trip in the other poll. But we have one vote for it being least likely to cause a bad trip in this poll.

For LSD there are lots of votes for it being the most likely to cause a bad trip in the other poll, and no votes yet for it being the least likely to cause a bad trip in this poll. That should tell you something about the psychological effects of LSD. They can be overwhelming, much more so than ayahuasca or pharmahuasca.
