I no longer use drugs or alcohol (been in recovery for 3 years now), however I had to take a U.A. today and apparently it came up positive for methamphetamine. I was shocked! I’ve never used “meth” or tried it. My addiction was alcohol and cocaine. I did request my U.A. to be sent to the lab for a 2nd opinion. Need to wait about a week for the results from lab. Can someone please give me more information on this. The product that I have been using (baught from GNC) is “meltdown”. this is a weight loss supplement. Thank you for anyone who can help.
