Kratom, an herbal substance from Southeast Asia, produces opioid- and stimulant-like effects and is used for managing withdrawal symptoms, pain, and mental health issues. Despite FDA warnings about potential adverse events like liver toxicity and seizures, recent FDA research suggests kratom capsules may be safe in high doses. Kratom is not a controlled substance in the U.S., but several states have banned its active alkaloids. Kratom products are marketed for mood, focus, and energy enhancement, with companies advising caution and responsible use.
