Five legal standards are:

1. Does marijuana have a known and reproducible drug chemistry?
2. Does marijuana have adequate safety studies?
3. Are there adequate and controlled studies showing marijuana’s efficacy?
4. Are marijuana’s therapeutic benefits accepted by qualified experts?
5. Are scientific data available for scrutiny?

To sustain the view that marijuana should remain in Schedule I, the prosecution team also had to show that marijuana has:

1. A high potential for abuse,
2. No currently accepted medical use in treatment in the United States, and
3. Unacceptable safety standards for its use under medical supervision.
