That's not quite the same tho. You can buy one bottle of beer if you want and even shots so if you bought a dozen 10mg cookies and they put them in bag for you then it's much the same as buying a box of beer.
Not to be argumentative, but they are saying any
package can contain only 10mg, which is a
single serving... so, if they applied the same type of rule to liquor, you would not even have the option to buy a 26'er or a 40oz, you would have to buy 26 or 40 little 1oz bottles... Beer, perhaps not a good example, since they come in individual bottles, but they wouldn't be able to package them in the cartons, you'd have to put it in a box when you buy them to carry them home.
It's not a big deal, just buy more servings, BUT, a 40oz bottle of liquor is MUCH cheaper than 40 1oz bottles isn't it?
I assume there must be some "equivalence" between the edibles and dried bud when it comes to possession limits in public... but you should be able to stock up at home... I don't know how they could know your food has thc in it though unless they send it off to a lab...
