It's interesting how researchers draw conclusions that fit their agenda. We were told for years that marijuana lowers the IQ of teenagers. What we were not told is that the study did not normalize for other factors such as alcohol and tobacco consumption. Why is that? because researchers probably found data that fit their agenda.

“There is much debate about the impact of adolescent cannabis use on intellectual and educational outcomes. We investigated associations between adolescent cannabis use and IQ and educational attainment in a sample of 2235 teenagers from the Avon Longitudinal Study of Parents and Children… Those who had used cannabis ⩾50 times did not differ from never-users on either IQ or educational performance.
“These findings suggest that adolescent cannabis use is not associated with IQ or educational performance once adjustment is made for potential confounds, in particular adolescent cigarette use. Modest cannabis use in teenagers may have less cognitive impact than epidemiological surveys of older cohorts have previously suggested.”
Yeah, but inhaling that smoke is great for the lunhttp://www.lung.org/stop-smoking/smoking-facts/marijuana-and-lung-health.html?referrer=https://www.google.com/gs.

Findings show study participants who began using marijuana at the age of 16 or younger demonstrated brain variations that indicate arrested brain development in the prefrontal cortex, the part of the brain responsible for judgment, reasoning and complex thinking. Individuals who started using marijuana after age 16 showed the opposite effect and demonstrated signs of accelerated brain aging.
...teens who engage in heavy marijuana use often show disadvantages in neurocognitive performance, macrostructural and microstructural brain development, and alterations in brain functioning...
diffusion-weighted magnetic resonance imaging and brain connectivity mapping techniques were performed in 59 cannabis users with longstanding histories of heavy use and 33 matched controls. Axonal connectivity was found to be impaired in the right fimbria of the hippocampus (fornix), splenium of the corpus callosum and commissural fibres. Radial and axial diffusivity in these pathways were associated with the age at which regular cannabis use commenced. Our findings indicate long-term cannabis use is hazardous to the white matter of the developing brain.
Weed may not make teenagers stupid, but it sure can make them act stupid!
Being a teenager makes them act stupid. The brain doesn't fully mature until one is out of their teens.
I support the legalization of marijuana. We waste so much fighting this. I don't think one helps the argument though here. Even if legalized it's not going to be legalized for teens, nor IMO should it.
Teens will smoke it regardless of whether or not it's legalized because that is what teens do but this doesn't help the issue.

Not a teenager but I knew someone who graduated from a prestigious engineering school with a 3.9 GPA who admitted to smoking weed just about every day, and I don't think anyone's advocating use, legal or otherwise, by teens.
