With DEA being the enforcement side of both the Title 21 and the CSA...This app should have a listing of all Title 21 violations/penalties. I don't think this app should have a DEA tab if it's not going to reference these types of things. **Developer response:** Thanks for your feedback! Have you tried our flagship app LawStack?
