A pivotal RCT in 116 cannabis-dependent adolescents found that NAC (1,200 mg twice daily) more than doubled the odds of a negative urine cannabinoid test compared to placebo (OR 2.4, 95% CI 1.1-5.2) (Gray et al., Am J Psychiatry, 2012) [76]
That slowdown signals metabolic adaptation, and that is when a second agent with a different mechanism provides the most benefit
Clinical research indicates that the most effective daily dosage for NAD+ precursors (such as nicotinamide riboside or nicotinamide mononucleotide) typically falls within the range of 250 milligrams to 500 milligrams per day for most adults, though some studies safely use up to 1,000mg per day for more robust increases in NAD+ levels
