“Activation of cannabinoid receptor type 2 has been shown to have anti-fibrosis function in skin and heart.

In this research, we aimed to investigate the role of cannabinoid receptor type 2 in pulmonary fibrosis in vitro and in vivo.

Our research indicated that activating cannabinoid receptor type 2 by a pharmacological method might be a potential strategy for pulmonary fibrosis.”  https://www.ncbi.nlm.nih.gov/pubmed/29262578

“In conclusion, we demonstrate that activating cannabinoid receptor type 2 by selective agonist JWH133 is a potential strategy for pulmonary fibrosis. Our researches offer a new choice for this life-threatening disease.” http://www.oncotarget.com/index.php?journal=oncotarget&page=article&op=view&path[]=21975&path[]=69664
