It amazes me that even while marijuana is finally being legalized it is still being viewed through the eyes of reefer madness paranoia.  14 Years for selling to a minor?? A store will lose its license for 6 months for selling liquor or cigarettes to a minor but weed will net you over a decade in the slammer>
There is going to be the same battle keeping kids from smoking weed and drinking as there has always been. 
This fallacy that there is going to be a dramatic rise in users of pot that needs to be feared. The truth is that after the initial coming out party, the number of pot users will slip right back into approximately the same percentages of society that are currently smoking it.

The idea of not selling pot and weed in the same store is laughable. What is the distance to be between the two? A city block, cab ride? And what about the clear reality that they will eventually end up in the same house regardless.
Glad it happened but the method is madness.
