Just within the passage you've quoted: vs. He's literally just told us that he don't know whether or not marijuana effects EQ (and I find "EQ" a dubious concept in-and-of itself), but then three sentences later, asserts that EQ development is more susceptible to pot use than IQ because... ummm... teenagers are pretty immature, right guys? Am I right, or what?!? Also worth considering: The guy who smokes a bowl and works on coding vs. the guy sinking into the sofa sitting through SpongeBob re-runs. The latter is more common, and IQ tends to decline with age regardless of environment. Did they control for that? I don't read marijuana studies anymore, they're just too political.While the study didn’t measure the effects of marijuana upon teenagers’ emotional intelligence, it’s likely they are dire.
Since teenagers’ EQ develops much later than their IQ, this area of the brain is even more susceptible to the negative influences of marijuana.
