Oh wow, ya, that kind of sucks lol. I can see why you couldnt play the autism card, she'd still have the upper hand =P.
My solution...
She's on probation so she has drug tests regularly (i'm almost positive of this, even if it's not a drug related charge she's on probation for, she has to get drug tested regularly). So bake some pot deserts.

Brownies, cookies, what ever you you think she'd be more inclined to eat.
Obviously dont use the amount it says to make the butter (1 ounce to 6 sticks of butter i think?) cut that in half or a 1/4 so that you dont have an office of stoned people. But enough to cause a positive reading on a drug test.
And voila, she is in violation of her probation and goes back to jail.
That's just what I'd do though
