Yeah, it's sort of like saying "the knife didn't cause them to die, they were just an undiagonosed hemophiliac and the wound failed to close properly." However, teasing out the steelman from this, what they mean is "becoming crazy is not a necessary effect of recreational drug use, but rather a contingent effect."
