Not sure where you are, in Colorado there are regulations in place as what can or can not be in your bud. I know Strainwise had some problems and pulled the flower from sale. You may be able to ask for an exchange. I am in a small town with only 2 dispensary's so I may be spoiled by the 1 that does get my business.
This is around 10 dollars worth of brickweed in mexico. Feel free to compare it to yours, lol.
You could at least let them know as a public service
They may be unaware and some people may not know better and smoke it
I suspect it would be worth the Karma points !
