Is there a place online to research Colorado state laws?

I am researching the legality of physicians diapensing prepachaged medecine out of their office, and I need to find the actual written law. I dont want to have to pay for a lawyer and I think if I can find the answers online it will be fine but I am having trouble finding a site that I can navigate through the statutes. If you know of one it would be helpful, and onw that has a search engine ould be even better - Thanks!
