Background Check: All fellowship offers are contingent on your ability to successfully pass a federal background check, which is required for logical and physical access to NIH facilities and systems. As part of the clearance process, you will be asked questions about a variety of topics including your citizenship, criminal history, and other personal information. One specific question you will be asked is “In the last year, have you used, possessed, supplied, or manufactured illegal drugs?” This question pertains to the use of controlled substances or drugs as defined under federal law. Please be aware that while marijuana may be legal or decriminalized within your home jurisdiction it remains illegal under U.S. federal law. The use, possession, supply, or manufacture of marijuana may preclude you from obtaining the necessary clearances to participate in NIH intramural training programs, even if you were initially offered a position. If you have questions about this policy or would like guidance on the clearance process, please reach out to oite@nih.govmailto:mailto: (please put “Eligibility Inquiry” in the subject line).
