What this research studies

This research aims to evaluate the abuse potential and pharmacokinetic profile of kratom, an herbal substance with opioid-like properties. The study will involve non-treatment seeking recreational opioid users who will participate in a randomized, double-blind, crossover design. Participants will experience different doses of kratom, along with positive control drugs and placebo, to assess subjective effects such as 'drug liking'. Blood samples will be collected to analyze how kratom is absorbed, distributed, metabolized, and eliminated in the body.

Who could benefit from this research

Good fit: Ideal candidates for this research are non-treatment seeking recreational opioid users who are interested in participating in studies related to substance use.

Not a fit: Patients who are not recreational opioid users or those seeking treatment for substance use disorders may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide critical insights into the safety and abuse potential of kratom, informing public health policies and treatment approaches.

How similar studies have performed: While there is limited research on kratom's abuse potential, studies on other substances with similar properties have shown success in understanding their effects and risks.
