This project will evaluate the joint effects of methamphetamine use, sexual risk behavior, and rectal gonorrhea/chlamydia on rectal and systemic inflammation.
WHY IS THIS STUDY BEING DONE?
It is important to know how methamphetamine influences inflammation. We are evaluating whether methamphetamine use and/or sexually transmitted infections influence levels of inflammatory markers (cytokines) in the blood and in the rectum. This study uses a behavioral treatment called “contingency management”, which motivates and rewards for quitting meth.
ARE THERE ANY BENEFITS IF I PARTICIPATE?
We cannot promise any benefits to you or others from your taking part in this research. However, contingency management has been shown to effectively reduce relapse rates in those with meth use disorder, yet the specific way this affects the brain is not fully understood. We aim to see whether money can be more appealing than drugs and activate the brain’s rewards system in those who have been dependent on methamphetamine.
WILL I BE PAID FOR MY PARTICIPATION?
You will be compensated for your time and effort for study visits in cash or gift card equivalent. The maximum total compensation for attending all 26 study visits is $1,364.
