LAND O'LAKES — A Pasco County assistant principal was arrested after deputies say she ate too many pot cookies and went to the hospital with an overdose.Donna Lynch Haff, 50, has worked for the Pasco County School District since 2008 and started as an assistant principal at Anclote High School in 2012, according to the school's online staff page.Haff was released Monday from St. Joseph's Hospital in North Tampa after overdosing on edible marijuana in cookies made with cannabis oil, according to the Pasco County Sheriff's Office. Deputies went to Haff's Land O'Lakes home and arrested her for possession of a controlled substance."The cookie lacked plant-like material," a sheriff's report said, "but tested positive for marijuana (THC)."Haff's 19-year-old daughter, Allison Danielle Haff, also was arrested. The daughter told deputies a cookie containing cannabis oil belonged to her, the report said. It also said both women "knowingly and intentionally" had the cookies in their possession. Deputies said they did not bake the cookies themselves.Allison Danielle Haff was arrested Sunday while her mother was still in the hospital. Donna Haff was arrested Monday. Both made bail and were out of county jail by Tuesday afternoon, deputies said.Donna Haff studied at the University of South Florida and Florida State University, where she graduated with bachelor's and master's degrees in education. She has been placed on administrative leave and hasn't yet been interviewed by employee relations investigators.After that meeting, officials will decide whether to take further action, such as suspension without pay, said district spokeswoman Linda Cobbe.Donna Haff could not immediately be reached for comment Tuesday. She is the second Pasco district administrator to run into drug-related troubles this year.In June, former Land O'Lakes High School assistant principal Shannon M. Schultz was arrested on charges of driving under the influence and cocaine possession.Schultz remains suspended without pay, pending the outcome of the case, Cobbe said.Times staff writer Jeffrey S.
