Effects of stopping cannabis use on thinking and mental health symptoms
Changes in cognition and psychiatric disorder symptoms during cannabis abstinence using a novel discordant twin design
This study is looking at how taking a break from cannabis affects thinking skills and mental health in adults aged 31 to 47, by comparing twins where one stops using cannabis and the other keeps using it, to see what changes happen over six weeks.

What this research studies
This research investigates how abstaining from cannabis affects cognitive functions such as memory, attention, and processing speed, as well as psychiatric symptoms in adults aged 31 to 47. The study uses a unique approach by comparing monozygotic twins where one twin abstains from cannabis while the other continues using it. This design allows researchers to control for genetic factors and focus on the environmental impact of cannabis use. Participants will undergo assessments over a six-week period to evaluate changes in their cognitive abilities and mental health symptoms.
Who could benefit from this research
Good fit: Ideal candidates for this research are adults aged 31 to 47 who are regular cannabis users and willing to abstain from cannabis for six weeks.
Not a fit: Patients who do not use cannabis or are not experiencing cognitive or psychiatric symptoms may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could provide insights into the cognitive and mental health benefits of cannabis abstinence, potentially guiding treatment strategies for individuals with cannabis use disorders.
How similar studies have performed: While there have been studies on cannabis use, this specific approach using discordant twins is novel and has not been extensively tested.
