Table 4. Logistic regression analysis of current smoking and the current and prior status of alcohol, depression and drug use.

Four logistic regression models were fitted for the status of smoking as outcome variable, with the smoking status at the baseline, and the statuses of unhealthy alcohol use, depression, and one of the four and drug uses (1. stimulant use; 2. marijuana use; 3. prescription opioid use; 4. heroin use) at the current and preceding surveys
