A digital intervention for reducing stimulant drug use

Would you like to cut down or quit using stimulant drugs (e.g., cocaine, crack, meth)? Yale scientists would like to invite you to use a digital tool on your smartphone that may help you with this goal. We are looking for adults who use stimulant drugs frequently and have some desire to cut down or quit to take part in an online research study. Participation will involve going to the website for a few minutes everyday for a month and completing three monthly online questionnaires. You can be compensated around $250 for completing the study.
