… or another one in your face, Drug Czar!
Via Marijuana Policy Project: Largest-Ever Study of Marijuana, Depression Finds Fewer Depressive Symptoms, Better Mood:
The new research appears to contradict statements by some government officials suggesting that marijuana is a cause of depression. For example, in a May 3, 2005, press release from the White House Office of National Drug Control Policy, ONDCP Director John Walters said, “Marijuana use, particularly during the teen years, can lead to depression, thoughts of suicide and schizophrenia.”
“Not only does marijuana not cause depression, it looks like it may actually alleviate it,” said Mitch Earleywine, co-author of the new study and associate professor of psychology at the University at Albany, State University of New York.
So is this just a small effect that could be open to interpretation?
So how could the drug czar be so wrong? (other than the fact that they like to lie and manipulate data)
It’s the junk science approach that they use. If, for example they study a group of depressed people and find that many of them use marijuana, they’ll link depression with marijuana use. However, it is more likely that depressed people are using marijuana as self-medication for their depression. This study is better, because is takes full populations and looks at the overall effect — and overall, those who use marijuana (whether depressed or not) are less depressed than those who do not.
