Pranayama breathing....?

Question

I understand that pranayama breathing, if done properly, can induce an acid-like state. I also understand that taking psychedelics such as lsd can bring about already existing, but "deep seated" mental issues such as schizophrenia and bipolar disorder or cause hppd. What i want to know is can pranayama breathing also cause these issues to arise, or is it a safe alternative?

**please no opinions on this subject - i am simply looking for answers to this question**

u can also explore www.virtuesproject.com and bahai writings on spirituality to get a grasp of the inner life and the world beyond.
