My classmate had his hernia on his navel operated on. And he then refrained from using CBD oil two weeks before the operation. He wasn't sure that the use of cannabis was prohibited before the operation in which he'd be given general anesthesia. He just stopped using it just in case it didn't cause any complications. Best Oklahoma dispensaries where he buys CBD oil supplies products to many people. I think good pharmacists are working in this company. So you can ask them a question on the hotline if you're very interested or worried about it! Good luck. I hope everything will be fine.
