Your statement about Ole Røgeberg analysis of Meier et al.'s New Zealand longitudinal study is a misrepresentation of the facts.

Røgeberg disagreed with Meier's statistical analysis and created an alternative model that he thought better accounted for the effect of Socio-economic status (but plenty of other researchers have criticized Røgeberg's analysis) , but this didn't "debunk" Meier's conclusion.

Røgeberg explicitly says in his abstract "Although it would be too strong to say that the results have been discredited, the methodology is flawed and the causal inference drawn from the results premature."

The conclusion everyone should draw is that smoking weed regularly (3 days/week, in this study)during adolescence may, or may not, cause a drop in IQ scores.

Anecdotally, I'd say the rare "all CBD, almost no THC" strains can kind of sober you up a bit.

I tried the experiment of intentionally smoking a bunch more Sour Diesel than I would want to. Following up with CBD Sour Tsunami (tested at high CBD and miniscule THC) actually muted the unpleasant effects and cleared my head a great deal.
