I've not read much into research with LSD, so I can't really speak about it specifically.
I have no doubt that there will be challenges and new problems to overcome in new fields of research involving these substances. You have to understand, these substances haven't been openly studied in relation to any medical or health benefit due to their being illegal. However, as laws and funding permitting such research allows, I'm all for looking into is.
This thread is about psychotropic drugs in religious rituals. Nothing about medical cannabis or even this LSD research is related to religious ritual. It's simply science.
I think you bought into the Nixon era lies and false reports to justify prohibition, and now you're afraid of any changes that might take place as we strip away those lies and look more deeply into this stuff. Please understand, I wouldn't dare say that someone should take anything that they explain is against their convictions. However, I also don't support blanket condemnation issued to those whose conditions are such that they are willing to look into the benefit of these things. You don't have to live with the symptoms they live with. Let them have the freedom to look into new possibilities and new treatments. It can't be worse than trying to force them to endure their symptoms.
