context_page_description: Mitragyna speciosa is a tropical evergreen tree in the coffee family native to Southeast Asia. It is indigenous to Thailand, Indonesia, Malaysia, Myanmar, and Papua New Guinea, where it has been used in traditional medicines since at least the nineteenth century. Kratom has opioid properties and some stimulant-like effects.
  As of 2018, the efficacy and safety of kratom are unclear, and the drug was unapproved as a therapeutic agent due to the poor quality of the research. In 2019, the United States Food and Drug Administration stated that there is no evidence that kratom is safe or effective for treating any condition. Some people take it for managing chronic pain, for treating opioid withdrawal symptoms, or for recreational purposes. The onset of effects typically begins within five to ten minutes and lasts for two to five hours.
  Common minor side effects include appetite loss, erectile dysfunction, hair loss and constipation. More severe side effects may include respiratory depression, seizure, addiction, and psychosis. Other side effects may include high heart rate and blood pressure, trouble sleeping, and, rarely, liver toxicity.
context_section_description: As of 2013, kratom has been studied in cells and in animals, but no clinical trials have been conducted in the United States. The United States Drug Enforcement Administration (DEA) stated in 2013: "There is no legitimate medical use for kratom". In April 2019, the United States Food and Drug Administration (FDA) stated that there is no evidence that kratom is safe or effective for treating any condition, and there are no approved clinical uses for kratom.
  Kratom leaves are commonly used by smoking or chewing, as a tea, powdered in capsules or pills, or extracted for use in liquids.
