How long does a workers comp/ personal injury case take?

i was burned at work on 2/3 of my arm 1st and 2nd degree burns. i was giving a required drug test as part of the workers comp claim and failed (pot). after i was terminated immediately with out workers comp or unemployment benefits. i called a lawyer and he believes i have a case either for workers comp payments of a personal injury. i was burned by there negligence. (other employee left something on the bench). how long will a process like this take, and do i have a good chance at a case? my family and i are in great emotional stress and i am in physical pain as well. please no smarts asses, i know no more smoking weed.
