Re-read the full context. He said they spend "the majority of their day high". That's a "very serious" addiction, because their dependence of the drug is erecting defenses in the conscious mind to the denial of the reality that they probably can't stop. On the contrary, if for example I need to take an SSRI to keep depression at bay, I would be perfectly content to tell you that I had a major depressive disorder, and that the drug helps me stay functional - I'm diagnosed, treated, and aware of the fact. Also contrarily, if I smoke a joint every Friday night with my wife after the kids go to bed because we want to relax, but if we can get a baby sitter we'll jump at the chance to go out for a night on the town without weed, then I'm not addicted - I just use the drug situationally because it's my preferred option.
