Another factor to consider is the knowledge of the particular airport security agent that is letting you through – if they don’t know much about CBD they likely won’t even notice it or care, whereas if they’re picky and know about CBD, they may decide to confiscate it from you. And if this agent happens to be in a country with strict laws, they might also call the police.
More human studies are needed to fully understand the range of risks and side effects that CBD oil may cause. Studies of CBD oil aren’t common. This is partially because Schedule 1 substances like cannabis are highly regulated, causing some obstacles for researchers. With the legalization of marijuana products, more research is possible, and more answers will come.
