Regarding the drug issue, here's a few names to Google:
Kirk Ziadie
Ramon Preciado
Karl Broberg
Jamie Ness
David Jacobson
Doug (Drug) O'Neill...yeah, that guy, but he hasn't had a positive in over three years now.

opcorn:
And, Maria Borell..not necessarily for drugs, but for her "love" of the animals under her care. Some may remember her as trainer of BC Sprint champ Runhappy. She was fired after the race, and garnered a lot of attention for how the owner did her wrong. She got a small string from Drawing Away Stables in the winter, and I think got one in the winner's circle before being let go. DAS also employed David Jacobson. Nothing to see there...cough cough..
Here's a pretty eye opening look at part of the problem:

I used to have a real savvy link/database for all the tbred and harness trainers who had any positives, and when I can find it again, i'll post it up. Damn shame these horses give their all, but for some of these **** sticks, it's just not enough. Until the NTRA issues and finances a nationwide drug testing panel--never happen--running the horses on meds that doesn't make them feel pain, will unfortunately continue the breakdown trend. And yes, I'm in the corner with those that think Lasix masks other drugs. May not be the case, but we'll probably never know.
