Would drug dogs be trained to sniff out modafinil?

With daily maintenance of generic at about $15 a month it is very affordable, and dogs would be trained to hit on Xanax before modafinil, and I have never heard of that happening. Odds are far less than 1%. Lots of credible stories (other discussion forums) of people taking international flights with no problems.
