Hey Everyone,

I saw a medical patches on my ex's forearm and am worried about my child's safety (he's special needs) when with him since I do not know what this is for or what it is. The patch is approx 2" squared, blue, and has lighter blue or white stripes on it. Any ideas? I want to make sure it's not for a narcotic, and if it is, I need to report it for safety. Thank you in advance!
