Correct; instead of armchair pharmacist-ing on some internet forum, we should collect actual data about its effects so that people can make more informed decisions about what/whether there are good uses for this chemical. Just like we do with other drugs.
Yeah, I definitely don't disagree that informal reports are useful too. Was just reacting to the idea that it shouldn't be studied at all because of some rumors.
No, that's not what we do with other drugs. No one goes to an IRB with "We suspect this drug is bad for people, we should run a study to find out," and gets approval for that study.
If you wanted to perform an observational study on whether or not people already consuming LSD are at heightened risk of stroke, I highly doubt the federal ban would affect that.
