(36,925 posts)Supposedly the study corrects for criminal convictions due to the illegality of cannabis compared to the legality of alcohol. So far so good. However, I could find nothing that suggested they correct for the fact that many employers test for cannabis, but not for alcohol. So in other words, the reality that cannabis users face with greatly diminished career options was completely ignored as a socioeconomic factor. Not to mention there's a host of other differences between those two drugs which make it rather like trying to compare cats and dogs. There's simply no way they can correct for all the variables involved.
It's also important to remember that psychological "science" is only a science in the most abstract sense. The efficacy of psychologists, witch doctors, and homeopaths just aren't that different.
