Important Updates: 

Application​ Processing

As a result of the cyber-attack on the Maryland Department of Health (MDH), the Office of Controlled Substances Administration (OCSA) issued temporary Controlled Dangerous Substance (CDS) registration letters.  The MDH data systems have been restored and permanent CDS registrations will be issued.  If you have already applied to the OCSA you should not reapply.

Due to the large number of CDS temporary letters issued, the permanent registrations will take time to process.  The temporary letters have an expiration date of 11/30/2022, the Department is working to have the permanent registrations issued by this date.  You can continue to practice with CDS if you have received a temporary CDS registration letter or your application was received prior to two weeks before your expiration date until the Department has made a final decision.

The permanent CDS registrations will be sent electronically to the email address listed on the application.  We will no longer issue paper registration certificates.

CDS registration verifications will continue to be limited.  The website will update the CDS search information as each permanent CDS registration certificate is generated.  Please conitnue to follow the guidance listed below.

For New or Renewal applications please apply online at https://egov.maryland.gov/mdh/cds​

For Pending registrations please contact​ Maryland.OCSA@maryland.gov​​​

​​​​CDS Registration Verifications are Limited at this Time

If a CDS registration was issued:

Prior to December 4, 2021 - Please proceed to the CDS Search page.

After December 4, 2021 - Please ask the registrant to provide the temporary letter that was emailed to them. **Note: If the registrant has not received the email, ask them to check their SPAM folder.

For pending registrations please contact Maryland.OCSA@maryland.gov

Temporary Expiration Date Extension

All temporary Controlled Dangerous Substance (CDS) registration with an expiration date of March 31, 2022 will be extended until November 30, 2022.

This expiration date extension only extends to registrants that have applied and received a temporary registration.
