Your opinion on what medications hoses should run on?

With more and more people wanting horse racing to go to drug free, such as the Kentucky Derby will be now, whats your opinion on it, i've been a jockey for 20+ years and when i first started there where tons of different medications a horse could legally run on, but over the years it has slimmed down and now some people say that bute and lasics should also be illegal to run on. Do you think these people are right?
