About 24% and 13% of the sample demonstrated clinically significant improvements in psychological distress from baseline to 5months, and 5months to 12months, respectively. Nearly 21% of the sample showed clinically significant improvements in psychiatric problems from 5months to 12months. Among all patients, men and those with more severe opioid dependence symptoms demonstrated the greatest psychological improvements. Many patients in MMT with PG experience improvements in psychological problems, including long-term improvement, regardless of the PG intervention offered.

Nicotine in e-cigarettes typically is labeled as mg/ml or percent nicotine, but these metrics may be difficult to understand. We examined whether adults who use e-cigarettes accurately can compare nicotine concentrations presented as mg/ml and percent and/or can identify the strength of concentrations presented using these metrics. 310 adults completed an online survey in 2020. Participants viewed nicotine concentration pairs (e.g., 24mg/ml vs 3%) and indicated which concentration was stronger or if they were equal. Participants also categorized nicotine concentrations presented as mg/ml (0-60mg/ml) and percent (0-6%) into strength categories (no nicotine, very low, low, medium, high, very high). "Correct" answers for the strength of each concentration (e.g., 30mg/ml is "high" nicotine) were based on the subjective opinion of e-cigarette researchers. When making direct comparisons, adults correctly identified that one concentration was stronger or that both were equivalent about half of the time (8.30 [5.08] of 19). Adults answered correctly more often when the stronger
