The Missouri Department of Health and Senior Services has issued a warning about a psychoactive product many people have probably never heard of. The department says Missourians should stay away from products containing 7-OH -- a natural compound derived from the plant kratom that is marketed as a way to deal with stress, pain and other maladies. However, health officials say it can have harmful opioid-like effects that can end in death in the worst scenarios. Kratom and 7-OH are not regulated and can be sold openly.
