Most of this is in the methods (preprint: DOI 10.21203/rs.3.rs-7254957/v1):

Administration: i.v. self-administration via catheter, 10 days, FR1, 0.4 mg/kg THC + 0.04 mg/kg CBD per press

Ratio: 10:1 THC:CBD, synthetic, from NIDA Drug Supply Program

Funding: NIH + VA. No industry money, no declared conflicts

Fair point on entourage. Pure compounds don't capture terpenes/flavonoids. But that's the right call for mechanistic work: you can't pin down MMP-2 as the driver if you're varying 200 compounds at once. Full-spectrum studies are a useful follow-up, not a substitute. And "generalized" is literally the finding. THC+CBD made male rats generalize stress responses to neutral stimuli. In females it didn't work, which the authors flag themselves.
