How do airports differentiate supplements from drugs?

I was just packing for an international flight, and realized that my little plastic bags of protein powder and creatine look an awful lot like the bags of cocain I see on tv. Does the airport have some way to identify drugs, or should I leave it at home?

I make my own mix of BCAAs creatine CLA etc. so I can't just bring it in the original packaging, it's all in carefully measured individual bags which look a lot like what I imagine a drug dealer might be carrying to sell, along with a bunch of vitamin pills.
