NIDA needs study participants who have never used alcohol, nicotine, or other drugs. These participants are often part of comparison groups (also known as “control participants”) for Healthy Control studies. You may also be eligible for a Healthy Control study if you:
Control participants may:
Please note, we do not give alcohol or drugs like marijuana, heroin, or cocaine to people who have never used these substances.
The purpose of this study is to develop new ways to measure nicotine dependence severity that may be useful in guiding development of new smoking cessation treatment targets. This study is accepting men and women who are 18 to 60 years of age and in generally good health.
This study is looking for participants who are non-smokers.
For research purposes, participants will be asked to:
This study takes place at the NIDA Intramural Research Program located on the Johns Hopkins Bayview campus in east Baltimore. There is no cost for participation and participants are paid for their time and travel
People with addictions often find it hard to choose the long-term benefits of abstinence over the short-term effects of using drugs. Based on studies in lab animals and humans, we think this is partly due to parts of the brain involved in certain types of learning and decision-making. We can test these basic functions using a simple task with pictures and odors.
The purpose of this study is to see whether performance in a learning task differs between people who have opioid-use disorder and people who don’t.
You may be eligible for this study if you meet all these criteria:

The purpose of this study is to examine the effects of a brain stimulation device called Transcranial Direct Current Stimulation, also known as tDCS in both smokers and non-smokers. tDCS has the potential to be used as a treatment for smoking addiction in the future.
This study is accepting men and women who are 18 to 60 years of age, are non-smokers and are in generally good health. Participation includes 3 study visits lasting 4-8 hours each.

Our study takes place at the National Institute on Drug Abuse (NIDA), located in Baltimore, Maryland. The duration of your participation may vary but typically range between 1-4 visits (12 max).
The purpose of this study is to develop tasks that examine cognitive functions related to learning and decision-making. This study involves a type of scanning known as functional magnetic resonance imaging (fMRI).
