MDMA (ecstasy) use produces neurochemical, behavioral, and endocrine changes similar to acute stress, acting as a chemical stressor. In rats, MDMA rapidly suppressed lymphocyte proliferation, decreased circulating lymphocytes, and increased plasma corticosterone. In humans, acute MDMA caused time-dependent immune dysfunction: CD4+ T-cells and lymphocyte responsiveness to stimulation decreased, while natural killer cells increased; total leukocyte count remained unchanged. Cortisol rose similarly to the rat model, suggesting MDMA triggers corticotrophin-releasing factor release from the hypothalamus, activating the HPA axis and sympathetic nervous system. These findings indicate MDMA ingestion may increase risk for immune system-related diseases.
