By 2025, cannabis is no longer just a policy debate or a counterculture reference point. Across the United States, 37 states plus Washington, D.C. have legalized medical marijuana, while legal sales growth, new product patterns like vaping and oils, and tightening lab testing rules are reshaping how the market looks. At the same time, use rates among teens and broader public attitudes about safety are adding a very human side to the figures, making the trend line harder to summarize than most people expect.
