“Cannabinoid receptors are expressed in human lung cancers”

  “Recently, CB1 and CB2 have been shown to be overexpressed on tumor cells compared to normal cells in various types of cancers, such as breast and liver, and therefore could be used as novel targets for cancer. In addition, several cannabinoids, including THC and cannabidiol, synthetic cannabinoid-agonists JWH-133, Win55,212-2, were shown to inhibit tumor growth and progression of several types of cancers, including glioma, glioblastoma multiforme, breast, prostate, colon carcinomas, leukemia and lymphoid tumors.”

“There are three general types of cannabinoids: phytocannabinoids, THC and cannabidiol, are derived from plants; endogenous cannabinoids, 2AG and AEA, which are produced inside the body; and synthetic cannabinoids, JWH-133/JWH-015, CP-55 and Win55,212-2.”

“Non-small cell lung cancer (NSCLC) is the leading cause of cancer deaths worldwide; however, only limited therapeutic treatments are available. Hence, we investigated the role of cannabinoid receptors, CB1 and CB2, as novel therapeutic targets against NSCLC…”

“These results suggest that CB1 and CB2 could be used as novel therapeutic targets against NSCLC.”
