No amount of weed can do that to a person. You lose the desire to bother posting a comment long before you become so messed up that you'd write like that, if it's even possible to get to that point on straight marijuana. I tend to overanalyze any sentences I write when I'm high but they still end up as sentences, and they're rarely grammatically incorrect. I know a couple of guys who smoke an ounce a week and still function at a far higher level than michejos. One is even an engineer, making six figures. Mr_Mxyzptlk is probably on the right track here.
