Cannabis Use Patterns Among Young Adults and Associations With Social and Health Outcomes.

This study is about understanding how young adults, aged 18 to 24, use cannabis regularly. Researchers want to find out about different patterns of cannabis use, such as how often it's used, what types of products are chosen, and how much is used. The study will follow participants over two years using a mobile phone app. The aim is to see how these patterns might change over time and what impact they have on young people's health and social lives. This information is important because cannabis laws are changing, and there's a need to understand its effects, especially in this age group where use is quite common. The study hopes to gather clear information to help develop ways to support young people and reduce any potential harms from cannabis use.

What is this study about?

This study is designed to learn more about how young adults, specifically those aged 18 to 24, use cannabis regularly. In places like Quebec, Canada, many young people in this age group use cannabis often, and laws around cannabis are changing. However, we don't know enough about the different ways they use it, how those patterns might change over time, or what effects this has on their health and social lives. This research aims to fill those gaps in our knowledge.

The researchers want to understand things like how frequently young people use cannabis, what kinds of cannabis products they choose, and how much they use. By following participants for two years, the study can see if these patterns stay the same or change. This will help us understand the real-world impact of regular cannabis use during this important time of life.

Ultimately, the information gathered from this study is really important. It will help doctors, policymakers, and support groups better understand cannabis use in young adults. With this knowledge, they can create better strategies and programs to help young people stay healthy and avoid potential problems related to cannabis, ensuring they have the best support possible.
