During his tenure at DEA Linden's accomplishments included the following:

  • Prepared legal guidance for agents and investigators on forfeiture of listed chemicals that are transshipped through the United States without providing proper notice to DEA resulting in the seizure and forfeiture of tons of listed chemicals worth more than $10 million.
  • Served as lead counsel in the hearing on DEA's proposed rule to schedule carisoprodol, the only hearing of its kind in more than twenty years.
  • Conducted consultation meetings with officials from Native American tribes and Native American religious groups regarding the sacramental use of peyote. Developed expertise in the religious use of controlled substances under the CSA and international drug control treaties.
