Could be, but it is still currently illegal.
And after the move by mexico, it is only going to help prove the points aginst legalizing marijuana, or any other substance.
why you ask? because its probably only going to be a few months until stories of overdoses, or vehicle accidents start taking the news by storm, because with the de-criminalization of ALL forms of use, there is noting to stop people from smoking, inhaling, or shooting up their choice of poison 24/7, no matter what they are doing.
I bet the death toll goes way up in the next six months to a year.
Some people crying about Michael jackson? heck, just wait till the "spring break" crowds hit mexico.
and all the while, the public attitude will change.

But this thread wasn't about legalizing anything, this thread was about a friend of the OP that got
arrested for possession.
It is illegal. My guess is, as a teacher, she will lose her job and possibly her career.
