Long-Term Cannabis Use and Hippocampal Volume. A comparison of long-term cannabis users with 5 informative subgroups on age-45 hippocampal volume. This figure shows means (and 95% CIs) on age-45 hippocampal volume, which were adjusted for sex and standardized on the full cohort (M=0, SD=1). Average normative volume is indicated by the reference line at the representative cohort mean of 0. Estimates below zero indicate smaller than average volume. Stars indicate mean volumes that were statistically significantly larger (p<.05) as compared with long-term cannabis users, after adjustment for sex. CA1-CA4=cornu ammonis 1–4. HATA=hippocampal amygdala transition area.
