UPDATE: Further lab testing found no evidence of Fentanyl on the flyers.
The update seems to have been made just a few days later as can be seen in the edit history of the post:
Despite this information being available to everyone who bothered to look for it, since then several websites have re-posted articles claiming a Fentanyl-laced flyer was found.
