Summary
This study tested whether N-acetylcysteine (NAC), an over-the-counter supplement, can help people who use both tobacco and cannabis reduce or quit their use. 59 adults who smoked cigarettes and used cannabis took NAC or a placebo for 12 weeks. Researchers tracked changes in days of use, cravings, and abstinence. The goal was to see if NAC could be a safe, accessible treatment for dual substance use.
