A kid in Saskatchewan gets in trouble for talking about marijuana in a school hallway.  From the description I am almost certain he was discussing this study on drugs and alcohol toxicity.

Kieran shared the information he found with classmates around the
lunch table, mentioning studies that suggest marijuana kills fewer
people than tobacco or alcohol. He also opined that marijuana use
should be legal in Canada. "I wasn’t selling any drugs, I was just
giving out statistics," Kieran said.

One of his fellow students
complained to Susan Wilson, the principal at Wawota Parkland School,
who in turn called Keiran’s mother on May 29. During the phone
conversation, Kieran said he was accused of "soliciting the sale of
drugs to minors and others within the school."…

And get this quote from the Director of Education for the school division:

…"Public schools are not public places like shopping malls where
students can gather and talk about any issue that they wish," he said.
"We have teachers and principals who have expectations for student
conduct in a safe and orderly climate."

What makes this newsworthy of course is not that a teen might be talking about pot (oh my stars and garters, what a shocker!!) or an interesting bit of research, but the school’s overreaction.  We are in the unfortunate season of graduation-linked teen deaths, usually from drunk driving or other alcohol related misadventure.  In that context, I wonder if the officials at this school think marijuana is the drug they need to worry about?
