Clear30 has built one of the largest datasets in existence on people reducing their cannabis use without entering treatment. The first paper from it, led by the Recovery Research Institute at Massachusetts General Hospital and Harvard Medical School, is peer-reviewed and published. Eight in ten had already tried a break that did not hold, and most did not want to quit.
