When compared with those who had never used cannabis, current users had 16% lower levels of fasting insulin and 17% lower HOMA-IR, findings that remained significant even after multivariate adjustment. They also had 1.63-mg/dL-higher HDL-cholesterol levels, as well as lower waist circumferences, both of which remained significant after adjustment.
