On Monday, there will be a seismic shift in horse racing. That's when the Horse Racing Integrity and Safety Authority will launch its Anti-Doping and Medication Control program and, in most states, will take over the responsibilities of drug testing and drug adjudications. With that date right around the corner, the TDN Writers' Room podcast presented by Keeneland brought in HISA's CEO Lisa Lazarus to give an update on what to expect once HISA takes over. Lazarus was this week's Green Group Guest of the Week.
