Kratom Powder: Effects, Risks and UK Legal Information
What Is Kratom Powder?
Kratom powder is a name commonly used for kratom products made from the leaves of Mitragyna speciosa, a tropical tree native to Southeast Asia. Traditionally, kratom leaves have been chewed or brewed into tea in some communities.
Kratom powder is typically made from dried, ground leaves. Its effects can vary depending on the plant material, product composition and individual response.
Kratom contains naturally occurring compounds, including mitragynine and 7-hydroxymitragynine, which interact with opioid receptors in the brain. Although kratom has attracted interest for its potential effects on energy, mood and pain perception, there is insufficient reliable evidence to establish it as a safe or effective medical treatment.
What Effects Can Kratom Have?
Kratom can produce stimulant-like effects as well as opioid-like effects. Some people report increased alertness or energy, while others experience relaxation, sedation or changes in mood.
The effects are unpredictable and may vary considerably between products and individuals. Kratom can also cause unpleasant reactions and may lead to dependence with repeated use.
How Does Kratom Affect the Brain?
The compounds in kratom interact with several receptor systems, including opioid receptors. These interactions may influence pain perception, alertness, mood and sedation.
However, kratom is not risk-free. Its effects can be difficult to predict, particularly when products have unknown concentrations or contain other substances. Combining kratom with alcohol, opioids, sedatives or other drugs may increase the risk of serious harm.
Kratom Side Effects and Safety
Kratom use has been associated with a range of adverse effects, including:
- Nausea and vomiting
- Dry mouth and constipation
- Drowsiness or dizziness
- Increased heart rate and raised blood pressure
- Agitation, confusion or hallucinations
- Liver injury and seizures in serious cases
Severe toxicity can cause life-threatening complications. Seek urgent medical attention if someone develops breathing difficulties, has a seizure, collapses or becomes difficult to wake.
Products sold as kratom may also vary in purity and composition, making their effects less predictable.
Kratom Dependence and Withdrawal
Regular kratom use can lead to physical dependence. People who stop after prolonged use may experience withdrawal symptoms, including:
- Muscle aches and spasms
- Anxiety, irritability and restlessness
- Difficulty sleeping
- Reduced appetite
- Watery eyes and a runny nose
- Diarrhoea and other digestive symptoms
Anyone experiencing dependence or withdrawal should seek advice from a qualified healthcare professional, particularly if other substances are involved.
CBD and Kratom: What Is the Difference?
CBD (cannabidiol) is a compound derived from cannabis, whereas kratom comes from Mitragyna speciosa. They are different substances, each with different effects and safety considerations.
Both should automatically be considered harmful. Kratom can cause dependence, and CBD products can interact with certain medicines. There is limited evidence about the safety of combining CBD and kratom, so professional advice is recommended.
Is Kratom Legal in the UK?
Kratom is controlled under the UK’s Psychoactive Substances Act 2016. The Act generally prohibits the production, supply, offer to supply, import or export of psychoactive substances, subject to statutory exemptions and other applicable provisions.
Anyone researching kratom in the UK should consult current government guidance or a qualified legal professional for clarification of the law.
