Notes: The following additional variables were included in Stages 1 and 2: gender, age, referral source, and past-month drug use. Two variables were included in the first stage only: age at first use of substances and living in a rural setting.
American Indians were not included as a separate group in Connecticut or New York because they made up a small proportion of the sample;
New York does not collect dates of services; thus, days to initiation cannot be calculated. Coef. = coefficient; CI = 95% confidence interval.
