Examining Effects of Domain Specific Episodic Future Thinking on Cannabis Use

April 10, 2022 updated by: Michael Sofis
The overarching goal of this online study is to compare the efficacy of six (weekly) sessions of Domain-Specific Episodic Future Thinking (DS-EFT) relative an active control condition on improving the ability to value future rewards and reducing cannabis use (grams and days of use), tobacco use, and alcohol use among.
