The Journal of Neuroimmunology, in their Sep. 2005 article titled "Cannabinoids and the Immune System: Potential For The Treatment of Inflammatory Diseases?" by J. Ludovic and Takashi Yamamura, stated:

“Studies from chronic cannabis smokers have provided much of the evidence for immunomodulatory [modifying or regulating the immune system] effects of cannabis in humans…

Cannabinoids can modulate both the function and secretion of cytokines [regulatory proteins] from immune cells.

Therefore, cannabinoids may be considered for treatment of inflammatory disease.”
