Morphine and marijuana, including tetrahydrocannabinol (THC), can suppress the immune system, potentially reducing resistance to diseases. However, some research suggests they might also enhance certain immune functions.

Area of Science:

  • Immunology
  • Pharmacology
  • Toxicology

Background:

  • Opioids like morphine and cannabinoids such as tetrahydrocannabinol (THC) are known to affect the immune system.
  • Previous research indicates varied immunomodulatory effects, with a focus on immunosuppression.

Purpose of the Study:

  • To review the immunomodulatory effects of morphine and marijuana components on host immune parameters.
  • To synthesize findings on how these substances impact humoral, cell-mediated, and innate immunity.

Main Methods:

  • Literature review of studies investigating the effects of morphine and THC on immune responses.
  • Analysis of reported alterations in various immune system aspects.

Main Results:

  • Most studies indicate immunosuppressive effects of morphine and marijuana use.

  • Some evidence suggests these substances may not always be detrimental and could potentially enhance certain immune functions.
  • A reduction in host resistance to cancer and microbial pathogens in animal models is observed.

    • Conclusions:

    • Morphine and marijuana exhibit complex immunomodulatory effects, predominantly immunosuppressive.
    • These substances can compromise the host's ability to fight off infections and cancer.
    • Further research is needed to fully elucidate the nuanced interactions between these drugs and the immune system.
