Alright matey
I've administered drug tests whilst working as a volunteer support worker/fitness instructor at a local drugs rehTests come in different types but, and it's a massive but, employers use a 5 panel. 99.9% of employers anyway. I know of no one that uses above a 5 panel. The 5 panel consists of amphetamine - speed etc, opiate - heroin etc, Benzodiazipines- valium etc, Exstacy, and cocaine.
You can others that do M Catt, and Miaow Miaow etc, and then you can get some that do roids. The ones that do roids etc, have to sent to labs and consists of Olympic Sports like testing, about ?500+ per test - NOT HAPPENING!!!!!
IN other words, you are safe as houses
