If a promising child with a high I.Q. turned into a dull adult opiate addict with a low I.Q., opiates might be suspected as the cause of the deterioration. The cases studied, however, pointed in the opposite direction. In a number of cases, addicts who had normal or superior I.Q.'s while addicted were found to have had subnormal I.Q.'s as children. The British Columbia researchers accordingly abandoned this line of investigation, on the ground that "the comparative psychological results were undependable." 27
The British Columbia report also noted: "We found most of the addicts very likeable people. On the whole, they were friendly, cooperative, interested and eager to talk freely and frankly about themselves. Many of them have sensitive minds, are interested in their own psychological reactions and in philosophical problems generally. They were, on the whole, not self-conscious, were self-possessed, courteous and helpful."
