Pills were found - larger white oval pill with ETHEX on one side and the numbers 2 and 6 carved on the back (with a line dividing the numbers). I've searched and searched and can't seem to identify them. A few of them were found on the ground near a local park in the neighborhood. I just want to know if they are dangerous and if we need to be on the lookout for anymore in the area ...

Thanks so much for your help
