This is what the 6th edition of Abnormal Psychology has to say about psychedelics:
"Stories in the popular press about people who jumped out of windows because they believed they could fly or who stepped into moving traffic with the mistaken idea that they couldn’t be hurt have provided for sensational reading, but little evidence suggests that
using hallucinogens produces a greater risk than being drunk or under the influence of any other drug. People do report having “bad trips”; these are the sort of frightening episodes in which clouds turn into threatening monsters or deep feelings of paranoia take over. Usually someone on a bad trip can be “talked down” by supportive people who provide constant reassurance that the experience is the temporary effect of the drug and it will wear off in a few hours."
I find it refreshing to encounter such a down-to-earth approach in a college textbook written by someone very well seen in the academic world.
