Marijuana Suppresses Immune Functions

Recent research published in the European Journal of Immunology, reveals why marijuana users are more susceptible to certain types of cancers and infections by suppressing the body’s immune functions.

The research, led by Dr Prakash Nagarkatti from the University of South Carolina, focused their research on cannabinoids, a group of compounds found inside the cannabis plant, including THC (delta-9 tetahydrocannabinol).

While most immune cells fight against infections and cancers to protect the host, a unique type of immune cell, myeloid-derived suppressor cells (MDSCs) actively suppress the immune system. The presence of these cells is known to increase in cancer patients and it is believed that MDSCs may suppress the immune system against cancer therapy and actually promote cancer growth.
