No THC? That's hard to say. Most CBD oil does have minute barely measurable quantities of THC, which will in no way be "mind altering" as consuming THC in larger amounts. However, minute quantities can be problematic for people being drug tested for work. If you have a question, contact the company you intend to buy from. Also, work with your HR or facility security officer to see what their policy is. Perhaps they can give you a waiver for the minute quantity of THC you may consume.
