text: have you ever had a co-worker that uses illegal drugs on the job.? seems like everybody knows whats going on,only won't admit it or say the word. nobody wants to see somebody fired and on the street. have encouraged person to seek counseling but refused. the law requires you to report it but if you don't feel in danger of life or his performance don't interfere with your work or others than is up to you what you do, either way try to talk to that person with help of other coworkers who know about it, most likely it wont help too much but at least you try to help, eventually that person will be fired anyway because the boss will find out, it's just a matter of time
