Response: Commentary: Totality of the Evidence Suggest Prenatal Cannabis Exposure Does Not Lead to Cognitive Impairments: A Systematic and Critical Review

摘要

We appreciate the interest Singer et al. (2021) have taken in our recent critical review of theliterature assessing the impact of prenatal cannabis exposure on cognitive functioning (Torres et al.,2020a). We concluded the current evidence suggests that prenatal exposure alone is not associatedwith subsequent clinically significant cognitive impairments.Singer et al. contend that nine of their papers should not have been included in our reviewbecause the “cohort was composed for a longitudinal study to assess developmental sequelae ofprenatal cocaine exposure, not cannabis.” We respectfully disagree. Not only was it appropriate toinclude findings from the papers in our review, but it would have been less than comprehensive, andfrankly, irresponsible, to exclude this information from our analysis. It is extremely troubling thatthe Case Western Reserve University (CWRU) group would make such an assertion, especially inlight of the fact that they readily drew conclusions about the impact of prenatal marijuana exposureon cognitive functioning of offspring in their papers.
