K2 aka Spice aka Synthetic Marijuana is apparently available over the counter
in bodegas in NYC and has recently drawn the attention of law enforcers and
law makers here. Apparently, K2 will not be detected when humans are drug
tested for opiates/cannabinoids.

Thinking contamination here, though given the efficacy of the drug (a first
and second place finish) (were drastic reversals in form evident with these
two horses?), the good news is that current equine testing regimens will
detect K2.

The restriction of medications which horses are permitted to train and race on
will have a direct effect on field size; entire generations of horses and
trainers are dependent on medication for training and racing purposes and lets
not even talk about drug testing at 2YO in training sales where some serious
money is changing hands based partially on brilliant displays of speed over a
quarter mile.

Bottom line: Average field size is now probably between 7-8 runners per race;
lets say a hard line approach to race day and training meds knocks that number
down to 5-6 runners per race. Effect on handle? Would YOU rather play shorter
fields in exchange for knowing all horses are running on hay oats water?
