Research objective: 

The proposed study has the following objectives:

1. To characterize the use of health care services and their direct costs (e.g. physician, laboratory, continuing care, mental health, hospital and pharmacy) of illicit drug users over the known longitudinal recurrent stages of illicit drug abuse, treatment, relapse and full abstention.

2. To characterize the differences in the use of health care services and their direct costs (e.g. physician, laboratory, continuing care, mental health, hospital and pharmacy) of illicit drug users over the know longitudinal recurrent stages of illicit drug abuse, treatment, relapse and full abstention across different primary drugs used, and different intensities of use; we hypothesize that health care service use and costs will be highest amongst most frequent illicit drug users.

3. To evaluate the variation in the use of health care services and their direct costs (e.g. physician, laboratory, continuing care, mental health, hospital and pharmacy) amongst the different observed patterns of poly-drug users; we hypothesize that health care service use and costs will be highest amongst poly-drug users.

4. To evaluate the use of health care services and their direct costs (e.g. physician, laboratory, continuing care, mental health, hospital and pharmacy) of illicit drug users accessing and not accessing methadone maintenance treatment (MMT) over the study period; we hypothesize that health care service use and costs will be highest amongst those not accessing MMT.

5. To evaluate if health care utilization and costs associated with chronic opioid dependence have been reduced once an individual starts and remains on MMT over the study period; we hypothesize that those who continue on MMT without interruption will have lower health care service use and costs than those who do not.

6. To evaluate the burden of utilization of health care services and their direct costs (e.g. physician, laboratory, continuing care, mental health, hospital and pharmacy) of illicit drug users during the initial days of periods of relapse; we hypothesize that health care service use and costs will be higher amongst those in periods of relapse.
