Summary
The purpose of this protocol is to learn more about impulsive decision making in people who
use methamphetamines. The investigators would like to know if a medication called naltrexone
changes how people make decisions. The investigators would also like to know whether changes
in decision making can be observed by MRI (magnetic resonance imaging).
The research is conducted in Portland, OR.
