Cannabis tops the list of most commonly used substances in Brazil. A recent study dug into the habits of cannabis users and how these habits link to other substance use and potential harm. Researchers looked at data from over 5, 000 people in Sao Paulo. They found four distinct groups of cannabis users.

        The study used a method called latent class analysis. This method groups people based on shared characteristics. The four groups were identified based on when they started using cannabis, how often they used it, and their use of other substances like tobacco and alcohol. The groups were named 'Polydrug', 'Former', 'Moderate', and 'Light'.

        The 'Polydrug' group stood out. They started using cannabis early and used it frequently. They also had the highest rates of other drug use, tobacco use, heavy drinking, and alcohol use disorder. About a quarter of cannabis users fell into this high-risk group. The 'Former' group also showed early and frequent cannabis use, but they had stopped using it. Both groups had stronger links to harmful outcomes.

        The study also found that about 30% of cannabis users are at higher risk for negative outcomes. This includes those who start early, use frequently, and mix cannabis with other drugs. Brazil's public health efforts should focus on preventing these risky patterns. Early intervention and targeted prevention could make a big difference.

        It's important to note that cannabis use alone doesn't cause these problems. The real risks come from early use, frequent use, and mixing with other substances. Understanding these patterns can help create better prevention strategies.

        The study shows that not all cannabis users are the same. Some are at higher risk than others. By focusing on these high-risk groups, public health efforts can be more effective. This approach could lead to better outcomes and fewer harms.

        Brazil has a lot of work to do in this area. By understanding the patterns of cannabis use and the risks involved, they can create more effective prevention strategies. This could help reduce the harms associated with cannabis use and improve overall public health.
