I just found out that one of my long-term employees is taking Kratom. He's a maintenance man with a bad shoulder. I've offered to pay for shoulder surgery, but he's terrified of going under the knife. He's been on a low dose of narcotics off and on for years now, but it's impossible for him to get a prescription now with all the addict panic going around. Should I be worried? The only thing I know about kratom is that it's legal in my state, but I need to know if he's going to get all addict or if the stuff's dangerous or what. He's kind of naive so I want to look out for him, you know?
