Can marijuana use become a problem?

Yes, marijuana use can become a problem when it begins to affect a person’s functioning, behavior, or well-being. This may include difficulty controlling use, declining performance at work or school, relationship problems, or continued use despite negative consequences.
Problems may develop gradually and may not be immediately obvious. Some individuals may initially view marijuana as low-risk, which can delay recognition of emerging issues.
The key concern is not whether marijuana is used, but whether use is causing impairment or is becoming difficult to control. When these patterns emerge, it may indicate a substance use disorder.
