16. Patients who are addicted to cocaine are sometimes using the drug to combat depression. As such, sometimes addicts are given antidepressant medications to prevent relapse.

users wishing to break the habit. The patients were put into 3 groups of 24, and given 1 of the 3 treatments at random. This two-way table illustrates the results.
