On Jan. 20, we reported on a statement from the American Psychological Association that a research paper, "Chronic Adolescent Marijuana Use as a Risk Factor for Physical and Mental Health Problems in Young Adult Men," had a statistical error.
The APA now says that statement, which was titled "APA Corrects Article Regarding Teen Marijuana Use," should not have said there was an error in the paper. Jim Sliwa, a spokesman for the APA, told NPR: "There was no error. The original release was labeled a correction but it should have been a clarification."
According to the APA, another researcher had asked the APA for a supplemental analysis of the data, which the study researchers supplied. That supplemental analysis did find a slightly higher probability of meeting criteria for a psychotic diagnosis in frequent marijuana users, but it did not significantly change the conclusions of the study data. Earlier versions of this article, including the headline, referred to errors in the paper's statistical analysis. We have removed those references to make it clear that the paper was not in error.
