Kratom (Mitragyna speciosa) Addiction

Kratom addiction, also called kratom use disorder (KUD) or kratom dependence, affects the brain and body.

What is Kratom?

Kratom (Mitragyna speciosa) is a tropical plant native to Southeast Asia, where its leaves have traditionally been used by laborers to reduce fatigue and relieve pain. Today, kratom is widely available in the United States and other countries in forms such as powders, capsules, teas, gummies, and liquid extracts.

A stronger synthetic compound, 7-hydroxymitragynine (7-OH), appears in some kratom products. These concentrated 7-OH products carry a significantly higher risk of kratom addiction and overdose.

Why Do People Use Kratom?

Some companies market kratom as a treatment for physical, mental, and substance use conditions. Many people use it to manage anxiety, depression, chronic pain, or opioid withdrawal symptoms on their own. However, kratom is not FDA-approved for any medical use, and its safety and effectiveness remain under investigation.

Kratom’s effects depend on the dose:

  • Low doses (1–5 g): Stimulant-like effects such as increased energy, alertness, and talkativeness
  • Higher doses (>8 g): Opioid-like effects including sedation, relaxation, and pain relief

How is Kratom Used?

Most people take kratom by mouth. Traditionally, people chewed fresh leaves or brewed them as tea. In the United States and other Western countries, companies sell kratom in processed forms such as powders, capsules, teas, liquid extracts, tinctures or concentrated products.

Some individuals mix kratom powder into sweet foods, smoothies, or citric juices (to enhance its potency and activate the compound faster), while others take capsules or concentrated extracts. The toss-and-wash method involves taking a spoon full of kratom powder then washing it down with water or juice. Because kratom products are not consistently regulated, strength and purity vary widely.

Is Kratom Legal?

The legal status of kratom varies across the United States and internationally. While kratom remains legal in many states, some states and local governments have banned or restricted its sale and possession. Because laws continue to change, individuals should review current state and local laws regarding kratom products.

Florida enacted the Kratom Consumer Protection Act in 2023, allowing kratom sales statewide with regulations such as a minimum purchase age of 21, product labeling requirements, and restrictions on adulterated products. In August 2025, Florida banned products containing synthetic or highly concentrated 7-hydroxy mitragynine (7-OH), including certain fortified extracts, gummies, and liquid shots. Traditional kratom leaf products remain regulated under the state law. Sarasota County maintains a complete ban on all kratom products.

How Kratom Affects the Brain

Kratom’s active compounds, mitragynine and 7-hydroxymitragynine (7-OH), affect brain signaling and help explain the stimulant and opioid-like effects of kratom. These compounds affect several brain signaling systems:

Opioid receptors: The same receptors targeted by prescription opioids. Activation can produce pain relief, relaxation, and euphoria at higher doses while driving tolerance, dependence, and kratom addiction with repeated use.

Dopamine system: Stimulates reward pathways in the brain, reinforcing use and contributing to cravings and addiction risk.

Serotonin and norepinephrine pathways: Influence mood, energy, and alertness, helping explain the stimulant and mood-enhancing effects reported at lower doses.

Synthetic 7-hydroxymitragynine (7-OH) binds more strongly to opioid receptors than naturally occurring kratom compounds, which can intensify opioid-like effects and increase the risk of addiction and overdose.

Dose-Dependent Effects of Kratom

The effects of kratom vary depending on the dose:

Low doses (1–5 grams): Stimulant-like effects such as increased energy, alertness, and talkativeness.

Higher doses (above 8 grams): Opioid-like effects including sedation, relaxation, euphoria, and pain relief.

Health Effects and Risks of Kratom

Kratom’s active compounds affect opioid, serotonin, norepinephrine, and dopamine receptors in the brain. However, experts do not fully understand how kratom causes many of its health effects.

Common adverse effects include: nausea, vomiting, loss of appetite, weight loss, constipation, dehydration, seizures, liver damage, kidney damage, respiratory depression, agitation, irritability, and psychosis

Product contamination is another concern. Some kratom products contain heavy metals, bacteria, fentanyl, or other opioids. These contaminants can increase the risk of poisoning, infection, and accidental overdose.

Because of this risk, people who use kratom regularly should be educated on harm reduction strategies, including the availability of naloxone for overdose prevention when appropriate.

Is Kratom Addictive?

Yes, kratom can be addictive. Its active alkaloids, particularly mitragynine, interact with the brain’s dopamine receptors, the pathways associated with pleasure and reward.

Regular kratom use can lead to kratom use disorder or addiction, a condition marked by tolerance, cravings, withdrawal symptoms, and difficulty controlling use. The risk is higher with frequent use of high-dose or synthetic 7-OH products.

Individual factors such as genetics, mental health history, and environmental influences may also affect addiction risk.

Signs of Kratom Addiction

Recognizing these signs early may help guide individuals to seek kratom addiction treatment. Common signs include:

  • Tolerance: Needing more kratom to feel the same effects
  • Cravings: Strong urges to use, especially when stopping
  • Withdrawal symptoms: Muscle aches, anxiety, insomnia, irritability, diarrhea
  • Loss of control: Using more than intended or inability to cut down
  • Neglecting responsibilities: Declining performance at work, school, or home
  • Continued use despite harm: Physical, emotional, or relationship problems
  • Social withdrawal: Isolating from friends, family, or activities

Kratom Withdrawal Symptoms

Kratom withdrawal occurs when regular use suddenly stops or decreases. Withdrawal symptoms typically begin 12–24 hours after the last dose and may include:

  • Muscle aches and joint pain
  • Anxiety and irritability
  • Insomnia
  • Sweating and chills
  • Nausea and diarrhea
  • Intense cravings

Withdrawal severity depends on dose, how often kratom is used, other substances involved, and underlying health conditions. Symptoms usually peak within 2–3 days and improve over 1–2 weeks. Medical supervision can ease discomfort and reduce relapse risk.

Treatment for Kratom Use Disorder

Kratom use disorder is a treatable. Effective care treats physical withdrawal symptoms and the behaviors that drive continued use. Clinicians often treat kratom addiction with approaches similar to opioid use disorder treatment.

Treatment plans may combine medication, behavioral therapies, counseling, and recovery support. Care is tailored to each individual and considers the severity of dependence, co-occurring mental health conditions, and the goals of treatment.

Medications Used in Kratom Addiction Treatment

Because kratom’s alkaloids act as partial mu-opioid receptor agonists, medications used for opioid use disorder may help manage kratom withdrawal and reduce cravings. Although the FDA has not approved any medications specifically for kratom dependence, clinicians may use certain medications to help manage withdrawal symptoms and reduce cravings when appropriate.

  • Buprenorphine: Stabilizes withdrawal symptoms and reduces cravings
  • Methadone: A long-acting opioid agonist used in some cases of severe dependence
  • Naltrexone (Vivitrol): Blocks opioid receptors to help prevent relapse after withdrawal
  • Clonidine and lofexidine: Helps reduce symptoms such as anxiety, agitation, sweating, and restlessness
  • Gabapentin: May help manage anxiety, insomnia, and muscle discomfort

The choice of medication depends on the severity of dependence, individual treatment goals, and clinical judgment.

Behavioral and Supportive Therapies

Treatment often includes counseling, behavioral therapy, and peer support. These approaches help individuals develop coping skills, manage triggers, and strengthen long-term recovery.

Harm Reduction

Because kratom products may be contaminated with heavy metals, bacteria, fentanyl, or other opioids, people who use it regularly can learn how to reduce these risks. Education about overdose prevention is key. In some cases, clinicians may recommend keeping naloxone (Narcan) on hand as a safety measure.

When to Seek Treatment

People who experience kratom withdrawal symptoms or struggle to control their use may benefit from outpatient addiction treatment in Sarasota, where addiction medicine, mental health care, and primary care services can be integrated into a comprehensive treatment plan.

Recovery from kratom addiction is possible. With medical guidance and supportive care, many people successfully stabilize their health and rebuild long-term recovery.
