The goal of this experimental study is to test how three weeks of cannabis abstinence impacts threat and reward processing in females with Cannabis Use Disorder. The main questions it aims to answer are:

Compared to using cannabis as usual, will cannabis cue reactivity increase throughout three weeks of abstinence from cannabis?

Compared to using cannabis as usual, will threat reactivity be elevated at weeks 1 and 2 of abstinence followed by a decrease at week 3 of abstinence?

Compared to using cannabis as usual, will non-drug reward reactivity be lower at weeks 1 and 2 of abstinence followed by an increase at week 3 of abstinence?

Compared to successful 3-week abstainers, will threat, non-drug reward, and cannabis cue reactivity differ in relapsers?

Researchers will compare females with CUD who abstain from cannabis for three weeks to those who continue to use cannabis as usual to see how cannabis abstinence impacts threat and reward processing.

Participants will:

Be randomly assigned to continue using cannabis as usual or abstain from cannabis for three weeks Visit the lab 6 times over three weeks, followed by a 1-month follow-up lab visit for the participants assigned to the cannabis abstinence condition Complete phone surveys every other day across the three week study period
