Controlled Substances: How to Order

Learn how to order a controlled substance for research purposes.

Become authorized to order CS

Before a lab can purchase CS, the principal investigator (PI) must have an approved Controlled Substance Use Authorization (CSUA).

Only controlled substances approved in the CSUA may be requisitioned.

Order through the CSUA Web application

CS are restricted from department orders and must be requisitioned through the EH&S Controlled Substance Use Authorization (CSUA) Web application.

The PI and CSUA Lab Contacts approved on the CSUA can initiate a requisition on the CSUA application's My Orders tab.

  • Contact your PI, CSUA Lab Contact, or the CS Program Manager to gain authorization to use the CSUA Web application.

Tip: Check the CS Product & Supplier Bulletin (PDF) for the latest CS procurement information by substance type and supplier.

How to requisition CS online

  1. Go to My Research Safety.
  2. Click the Authorizations tab and select Controlled Substance Use Authorization to open the CSUA Web application.
  3. In the CSUA application, select the My Orders tab to create a CS requisition.
  4. Important: The PI must authorize the request by signing the requisition's Supplemental Information Report (printed from the CSUA application).
  5. Submit the signed Supplemental Information Report to EH&S for review.

After EH&S reviews and approves your CS requisition, a UCSD Procurement & Contracts Buyer will place the order through Marketplace. Monitor the purchase order number in either the CSUA application or Marketplace.

Important – Transfer of controlled substances is prohibited. A "gift" of CS from a company or an agency must go through the same request and approval process with zero dollars for the cost.

Allow for delivery time

Plan ahead. Controlled substances are obtained from suppliers and there is no on-site stock. Note that California Precursors must be purchased from a California supplier and have a delay period of 21 days. Plan to order quantities sufficient for a 3–6 month period to minimize expired waste and risk of theft.

  • Schedule II: 3 weeks
  • Schedule III – V: 10 days
  • Listed chemicals (if their hazard class requires shipment by ground transportation): 20 days
  • California precursors (due to 21 day CA Dept. of Justice review period): 40 days


CS orders are available for pickup after the primary Lab Contact receives an arrival confirmation e-mail. The e-mail states where to pick up the order. The person who picks up the order must have a UCSD ID and be listed as an authorized recipient on the CSUA.

After receiving your order, return directly to the approved secure storage location and secure the shipment until needed. File the Log Sheet in the appropriate Log Book.

CS Log Sheets

EH&S provides a CS Log Sheet for each CS container when the item is picked up. Each container is labeled with a unique identification number for ease of inventory documentation. Do not transfer a CS from the original container for storage purposes. Keep it in the original container.

Obtain replacement Log Sheets here, or contact the Controlled Substance Program. Include the container identification number in your request.
