Studies at NIDA

If you are in generally good health, you may be able to join one of our research studies. It's free to join, and you will be paid for your participation. All study participants are monitored while they are in the study to protect their health and safety.

We conduct research focused on substance-related topics, including nicotine, alcohol, opioid, cocaine, and marijuana use. Research participants may include people who use any of these substances occasionally as well as people who use them daily. We also need people who have never used nicotine, alcohol, or drugs like heroin, cocaine, and marijuana.
