Short answer: Combining kratom and alcohol is not considered safe. Federal health agencies report that many of the most serious kratom-related outcomes, including deaths, involved kratom used together with other substances. Alcohol is a central nervous system depressant, and stacking it with kratom adds risks to the brain, breathing and liver.
If someone is very drowsy, hard to wake, breathing slowly or not breathing, call 911 immediately. Poison Control is available 24/7 at 1-800-222-1222.
Why the combination is risky
1. Added sedation and breathing effects
Kratom’s main alkaloids act on the brain’s opioid receptors, and at higher amounts kratom is reported to have sedating effects. Alcohol also depresses the central nervous system. Together, they can increase drowsiness, impair coordination and judgment, and — especially with other depressants such as opioids or benzodiazepines — raise the risk of dangerously slowed breathing.
2. Strain on the liver
Both alcohol and kratom are processed by the liver, and cases of liver injury have been reported in people using kratom. Heavy drinking is a well-established cause of liver damage. Using both adds to the liver’s workload, and anyone with existing liver disease should be especially cautious.
3. Masked effects and overuse
Kratom can have stimulant-like effects at lower amounts, which may make someone feel less impaired by alcohol than they actually are. That can lead to drinking more, or to risky decisions such as driving.
4. Unknown product strength
Kratom products vary widely in alkaloid content, and some — especially extracts and 7-OH products — are far stronger than natural leaf. Combining an unpredictable product with alcohol makes the overall effect even harder to predict. See Kratom Powder vs. Capsules vs. Extracts.
What the research says
The National Institute on Drug Abuse notes that many people who use kratom also use other substances, and that case reports link combinations involving kratom with severe adverse effects, including death and liver problems. CDC analyses of kratom-involved overdose deaths found that most also involved other substances. The FDA has likewise warned that serious adverse events involving kratom frequently involve other drugs.
Research specifically on kratom plus alcohol is limited, which is itself a reason for caution: there is no established “safe” way to combine them.
Other combinations to avoid
- Opioids, including prescription pain medicines
- Benzodiazepines and other sedatives or sleep medicines
- Some antihistamines and muscle relaxants
- Other stimulants, which may strain the heart
If you take any prescription medication, ask a doctor or pharmacist before using kratom. Read more in Kratom Side Effects and Risks.
If you’re using both regularly
Regular use of both kratom and alcohol can make dependence and withdrawal more complicated. Alcohol withdrawal in particular can be dangerous, so do not stop heavy drinking suddenly without medical advice. A doctor can help you plan safely. SAMHSA’s free, confidential National Helpline is open 24/7 at 1-800-662-4357. See also Kratom Dependence and Withdrawal.
Frequently asked questions
Can you drink alcohol with kratom?
Health agencies advise against it. Both affect the central nervous system and the liver, and serious kratom-related harms frequently involve other substances such as alcohol.
Does kratom make alcohol stronger?
Combining them can increase sedation and impairment and raise the risk of slowed breathing, especially if other depressants are involved. Effects are unpredictable because kratom products vary in strength.
Is it safe to take kratom the day after drinking?
There is no established safe interval. If you have liver concerns or drink heavily, talk with a doctor before using kratom.
