Ok so this headline seems a bit misleading after reading the actual article itself. They basically did two sessions one with a placebo and one without for every participant and looked at their brains response to pain under LSD. They only saw how the drug changed the pain response/neural pathways while on the drug. They didn’t do any testing on any lingering effects post-session. To me “reshapes the brain” implies some kind of long term effect like vapes can from just one hit.

[This] study only included healthy volunteers who were not experiencing chronic pain. Therefore, it is unclear how LSD might affect individuals with chronic pain conditions, who may have different brain connectivity patterns than healthy individuals. Further research is needed to explore whether LSD could be effective in alleviating chronic pain in patients and how it compares to other pain management strategies.

Cool study, but it's a bit limited because of this. I was hoping they would find something analogous to how MDMA might help treatment-resistant depression.
