Would my past trouble bar me from joining

This is eating me up but recently, I’ve been very interested in applying to join my local police department (North California). However, I just recently found out that polygraph test is a requirement. I’m a fresh grad out of college working my 2nd year at a corporate job. In my first year, the stress got to me and I started using adderall to get through some tough days at work. It led to me selling some of my addies to a couple buddies at work. Would this bar me from joining the field?
