 involves ingestion of the plant’s raw leaves or consumption of teas that are brewed or steeped from the leaves. Kratom leaves are used for their complex, dose-dependent pharmacologic effects. Low to moderate doses (1-5 g) of the leaves reportedly produce mild stimulant effects that enable workers to stave off fatigue. Moderate to high doses (5-15 g) are reported to have opioid-like effects. At these doses, kratom has been used for the management of pain, diarrhea, and opioid withdrawal symptoms, as well as for its properties as a euphoriant. Very high doses (>15 g) of kratom tend to be quite sedating and can induce stupor, mimicking opioid effects... .. Most of the opioid-like activity of kratom has been attributed to the presence of the indole alkaloids, mitragynine and 7-hydroxymitragynine. Both compounds have been shown to have analgesic and antinociceptive effects in animals, although 7-hydroxymitragynine is more potent... in Southeast Asia, it has long been recognized that individuals will seek out and abuse kratom for its euphoric and mind-altering effects and that chronic users can become tolerant of, physically dependent on, and addicted to kratom. Kratom addiction is considered such a problem that many Southeast Asian countries have outlawed the use of kratom." \\ involves ingestion of the plant’s raw leaves or consumption of teas that are brewed or steeped from the leaves.

 +"The clinical effects of Kratom are dose-dependent. At low doses, Kratom produces a stimulant effect; at higher doses, the opioid effect predominates... M. speciosa Korth is a plant made up of more than 25 alkaloids that vary in specific composition depending on the plant's geographical location... Mitragynine is approximately 13 times more potent than morphine, while 7-hydroxymitragynine (a minor component of M. speciosa Korth) is four times more potent than mitragynine... A withdrawal syndrome has also been described in chronic Kratom users reporting irritability, yawning, rhinorrhea, and diarrhea. One contemporary case report describes a 44-year-old patient who manifested the following signs of withdrawal from Kratom: “anxiety, restlessness, tremor, sweating, and cravings for the substance”..." \\
