She needs a lawyer, no way around it if she wants to walk on this. Three plants are nothing much to be concerned about. They always charge the highest they can come up with so there'll be a better chance the defendant will plea bargain and it won't even go to court. if this is her first offense most likely she'll end up with simple misdemeaner possession and possibly probation but I would expect her to not receive any more time than what has already been served.

Get a lawyer.
