years ago after using some kiff and popcorn bud to make butter, I threw the left over plant material on the compost pile. My wife rang me at work the next day, to let me know the lab wouldnt stand up , come when called , eat a treat or respond in any of her usual ways. We were about to take her to the vet when the wife had a look around the yard and could see what the dog had been eating, after a few hrs the dog came good.
