Maybe a sentence longer than one year would be appropriate. Her ravaged complexion in the mug shot photo makes it clear that she has an addiction problem. She should be detained to the point where resumption becomes statistically unlikely, which for most hard drugs would be two years. As for punishing her for her involvement with an organised drug-dealing ring, let's remember that the drugs that this group of people were selling were not soft, non-addictive, so-called "recreational" drugs(whose prohibition is questionable), but rather this ring was dealing hard drugs that cause physical addiction and death. That can't be taken lightly.
I'm not being an anti-drug fanatic. 70% of Americans of my age group(40's & 50's) consumed recreational drugs during their high school and college years, but crystal meth isn't a recreational drug. It's addictive, deadly, poison. Someone could have died from the drugs Ms.Bobek sold.
