Conditional Release is up to the judge. Usually the judge would say stay out of trouble for x amount of months and pay this fine and do some community service.. and If you do all of that, then the conditional sentence is over. It's called a suspended sentence around here (not sure if it's the same).

From the NORML website.

"The penalty for possession of a small amount (less than 42.5 grams) of marijuana is a fine of up to $200 and possible requirement of drug education."
