“Recent research has indicated that cannabinoid-based therapies might be effective in ameliorating the most important symptoms of COPD.”

“Researchers have observed that cannabinoids can be bronchodilatory, immunosuppressive, and anti-inflammatory, suggesting that cannabinoid-based therapies might offer safer and more effective treatment options for COPD.”

“Additionally, studies have suggested that cannabinoids might help promote better sleep, support the immune system, work as an expectorant, relieve pain, and have anti-microbial properties.”
