<human>: Reddit, I've done fucked up.  Was havin a great night down in my Utahn hometown visiting my parents, then went to this girl's house to smoke a joint and hang out for a bit.  We didn't finish the jay so I saved half of it for the ride home.  

About 5 minutes before I get off the highway I get pulled over for speeding.  Soon enough cop takes me out of the car because it reeked of smoke.  Me being the *fucking moron* that I am didn't even toss the joint out of the window.  I knew I was fucked if they searched the car so not knowing what else to do I admited to smoking the half joint.  Go through field sobriety test, get arrested for DUI Metabolite (that is what the officer kept referring it as; one of the question I have is what this is/does it help me). *God, what will my mother do when she finds out about this...*

I spent the night in jail and paid ~$600 to get my car back.  They told me to call back to arrange hearings in 5-8 days.  This all happened on Sunday night. What I need to know now is what am I looking at as far as penalities. 

Obviously I'm figuring probation, community service and fines.  But will my license be suspended?  Approximately how much will the fines be?  Does the fact that it is a DUI Metabolite improve my situation?  How does that compare to a regular DUI?  Should I be getting a lawyer even though it is a pretty clear cut case?  I don't make very much money, so I'm trying to keep my costs down.  Essentially, would the cost of hiring a lawyer balance out with a reduced court fine? Or even, is there a possiblity of the case getting thrown out? (too much to hope for I know)

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Got arrested for DUI because of half a joint.  What do I face now? How do I prepare, short of getting a lawyer?
