Could you explain to me if the following situation taken from the TV series "The Practice" is realistic?

There’s cocaine found in a girl’s room. It’s her brother’s, but she had it the time of the raid. The brother jumps bail, the prosecution pinches her because she tried to hide the drug. Anyway, the following might be more realistic. 200 grams with the intent to distribute is automatic: the trafficking charge is statutory, so, she would probably do 15 years.
