My main point is that its about what people do in their personal time, its not something which is specific to Harness Racing or that is really even about Harness Racing. But when people see headlines about race fixing (which I have still never heard anything substantial about yet) and drugs in racing its misleading and unfairly damaging in an unfair way. Im not sure there is a lot of evidence that the recreational use of MDMA is any more damaging to the individual or others around them than that of alcohol. But it is illegal, potentially dangerous?? and as such no-one should be doing it and certainly not supplying it.
I think its totally unfair for you to say "with such attitudes it makes me wonder what they think is ok to put in a horses system".
