Yeah, she probably had twenty kilos of pot hidden internally.

She could easily have been packing a small quantity of hash, which if ingested would cause her to test positive for marijuana.
Occam's razor. What is the simplest explanation?
1. A guard permitted her to chain smoke a large quantity of marijuana in her jail cell.
2. She was able to smuggle in a small quantity of hash (hollowed out tampons are often used for this purpose), which she ingested in jail.
3. She ingested a large amount of marijuana or a small amount of hash in her car during the 10 minutes or so that she was alone while the officer was checking her driving license.
