Synthetic THC forms like nabilone and dronabinol have shown anti-anxiety properties comparable to benzodiazepines.

“there is some old evidence from like I'd say the 70s or early 80s where they were using synthetic forms of THC like naalone which is something you can get in Canada or Marinol or dronabinol which I think is what's accessible in the states where they did find some evidence to suggest it was on par with like a benzodiazapine like diazapam or something I can't remember exactly what the comparator they'd used there but there was some evidence for there being some anti-anxiety properties of THC”
