To the Editor: In his Editorial accompanying
our paper on cognitive functioning in long-term heavy cannabis users,1 Dr Pope2 makes
inferences that question the validity of our findings. We point out that the
possible confounding factors that Pope alludes to were in fact controlled
in our study. We also wish to clarify other issues that he brings up.
