What are symptoms of someone with a cocaine problem? [View All]

[undeterred]

I have a co-worker who is really irritable and moody. He's a bully towards me half the time. Other times he's in an ok mood. He calls in sick a couple mornings a week. I looked up his court records and he has a conviction for possession of cocaine and some other drugs that is 3 years old. Either something is really affecting his moods or he is a total asshole. I wouldn't mind seeing him fired but I don't know if I am really reaching here.
