Yes, but on the other hand -- recently I've had a relatively persistent flu and decided to visit a doctor. After ~10 minutes I've been prescribed Levofloxacin antibiotic (w/o even doing blood work). I've bought the antibiotic and even got some probiotics; back at home, I've decided to do basic overview and research what I'm about to administer, as (luckily) I've never been treated before w/ drugs of such group. As it turns out -- this medicine do have frightening side effects, which may occur months even years after the initial 5-day administration. The side effects are potentially life long and may cause various disabilities. There are clinical studies which do provide very strong evidences about these side effects; numerous class actions against given pharmaceutical companies and blogs, where people are writing about the hell they are going through.
I'm in EU, but FDA warns about these potential issues and recommend prescribing fluoroquinolones as last line of treatment.

Honestly, I don't buy this argument about the numerous side-effects preventing further reasearch of psychedelics.
Psylocibin/MDMA should be available for research and even as last line of treatment, I believe, thousands of people will benefit.
