“Heavy cannabis users had decreased frequencies of human leukocyte antigen (HLA)-DR+CD38+CD4+ and CD8+ T-cell frequencies, compared to frequencies of these cells in non-cannabis-using individuals.
Heavy cannabis users had decreased frequencies of intermediate and nonclassical monocyte subsets, as well as decreased frequencies of interleukin 23- and tumor necrosis factor-α-producing antigen-presenting cells.
CONCLUSIONS:
While the clinical implications are unclear, our findings suggest that cannabis use is associated with a potentially beneficial reduction in systemic inflammation and immune activation in the context of antiretroviral-treated HIV infection.”

“We found that heavy cannabis use was associated with decreased frequencies of activated T cells and inflammatory antigen-presenting cell (APC) subsets, suggesting a potential immunologic benefit of cannabinoids through decreased immune activation in HIV-infected individuals.
In summary, our work demonstrates that heavy cannabis use is associated with lower markers of inflammation and immune activation in HIV-infected, ART-treated individuals.
These findings have clinical implications, as cannabinoids may have an immunological benefit and nonpsychoactive cannabis derivatives could be investigated as novel therapeutics to be used in conjunction with ART to aid in reduction of persistent inflammation.”
