The pro pot lobby is propagandizing this issue harder than any I recall in recent memory (If one excludes the Dem machine).
How the studies showing no negative impact are flawed:

And here’s evidence pot use among high schoolers has risen dramatically:
https://www.denverpost.com/2017/12/22/police-across-colorado-questioning-youth-marijuana-use/
“In a survey this year by the Rocky Mountain High Intensity Drug Trafficking Area, a federally funded agency that coordinates drug enforcement activities in a four-state region, 86 percent of Colorado resource officers said they believe marijuana use among students has risen dramatically. That’s up from 82 percent who said the same last year.”
Basically, there’s big money in under sampling biased survey information etc. to hide the rise in drug use among high school students in Colorado. Schools get to decide how to deal with it and they have relaxed enforcement. But counselors and resource officers on campus have noticed an uptick and I’ve read another study somewhere about declining graduation rates but that information seems to be deep sixed because the propaganda machine is on and cranking at high speed. Ask yourself how many high school students would prefer to do their homework or get high. Students literally lack sufficient brain development to make decisions at that age but they are instantly all too smart and mature to break any rules about smoking pot in Colorado.
Oh it’s hard to find buried statistics under the pile of propaganda but this article says Colorado’s teens lead the nation in pot use:
“A powerful marijuana industry lobby has emerged that sued Colorado to stop restrictions on advertising to protect children, and is now pushing back against municipal regulations to keep pot stores away from schools and day care facilities in other states,” said Kevin Sabet, president of Smart Approaches to Marijuana (SAM).
