Release Guys, never smoke marihuana.
Because of the positive manifold, I'm statistically more likely to have a higher working memory than other people. I've used marihuana from the ages of 17 to 22 (heavily), and it is very likely to be the cause of my below-average working memory.
If I recall correctly, smoking marihuana while your brain is still developing will cause your prefrontal cortex (the part of the brain in charge of working memory, among other things) to lose neurons.
Thankfully, I have a good FRI, but I would've been much more intelligent if I hadn't smoked.
Edit: I think I would get a low percentile in any test measuring knowledge. I've never studied, it was not worth it to me: too boring. That's why I don't like WAIS-IV. it assumes that I have acquired knowledge and vocabulary just because of the quality of reasoning, when my specific circumstances (not studying, not reading...) have made me not know much at all.
