Workers comp? I live in a legal state but would still have to take a test.

Hi I live in a legal state but have recently experienced a repetitive motion injury I believe is caused by work. I’m college age and my parents are telling me to go on workers comp until I finish school which would be great but I know I can’t pass the test and they don’t know I smoke, even though it’s a legal state. Does anyone have any recommendations on what to do? For context I work a job that requires lots of heavy lifting and have been there for two years so I don’t want to lose the position I’m in as this is the most money I’ve ever made. Thanks I’m pretty worried and don’t know who to talk to about this.
