It is addictive as hell. I don't think it is as insidious as other drugs (alcohol or crack are more destructive to others) but it is good at getting a grip on you and making you feel you need it to function. How many times have you heard, "I can't function properly till I have had at least 2 cups of coffee"? Once I got the need for it out of me, I found the need I felt was entirely artificial. I think some of it is chemical based and some is mental.
