Figure 6.

Altered plasma levels of macrophage inflammatory protein (MIP) 1α in plasma of heavy cannabis users compared with noncannabis users. Plasma levels of MIP-1α was assessed as part of a multiplex Luminex assay. Data are shown as pg/mL. Individuals are classified as noncannabis users or cannabis users stratified by moderate or heavy cannabis use as determined by plasma quantities of 11-nor-carboxy-tetrahydrocannabinol. Each individual is represented by a single point. Horizontal bars indicate the median value.
