It’s already known smoking marijuana may increase risk of heart problems and that eating a lot of highly processed foods may also raise the risk. New research suggests the combination of smoking cannabis and eating a diet of highly processed foods further raises cardiac risks by weakening the immune system. University of South Florida researchers used state-of-the-art technology to measure effects of cannabis smoke in the heart, spleen, lungs and brain. The effects were detected within two hours. Secondly, the study points to the longer-term or chronic harm inhaled cannabis smoke has on the immune system in people who consume processed or packaged foods rich in seed oils. Authors say cannabis amplifies that chronic inflammation.
