Uruguay Cannabis Market Dataset: CBDT Framework Natural Experiment Validation (2017-2025)

This dataset documents Uruguay's cannabis market from 2017-2025, capturing a natural experiment where legal cannabis quality (THC potency) systematically increased from 3% to 20% while price remained constant at approximately $1.40/gram. Key Finding: When Uruguay increased legal cannabis from 9% to 15% THC in December 2022, sales increased 84% (1,774 to 3,258 kg) in one year while price remained constant, isolating quality as the primary driver of legal market adoption. The data validates the Consumer-Driven Black Market Displacement (CBDT) Framework across four distinct quality eras. Statistical validation shows the framework explains 92.9% of variance in adoption rates (R² = 0.9288, p = 0.036) with mean absolute error of 2.0 percentage points.
