Let me get this straight....

i'm on probation for a gross criminal vehicular operation charge
i was 18 and
due to my cell phone i caused a serious accident, and luckily no one died
Don't you mean "I used my cellphone while driving and caused an accident"? Just because the accident was "due to your cellphone", last time I checked, mechanical devices don't drive, so you are 100% guilty for getting distracted while driving.
Just because you used drugs doesn't mean that once you stop using it that you're completely clean; it is STILL in your blood-stream not just for one month, but more than that.
When you are giving probation/parole, the law is giving you a second chance to redeem yourself and start anew, but you ignored that and you violated that, and now you're going to pay the price for violating the probation.
I say 30 days in jail is justified for you; don't violate your new given freedom by the law again.
Try and stay COMPLETELY clean once you get out. If not....just enjoy the ongoing cycle of being in and out of jail. Your record isn't going to be too pretty.
