As defined by the Standards of Student Conduct:
Granting an exemption from resolution via a conduct conference or hearing as described in Section 5.F.3., or any sanctions that may result, in cases involving underage drinking or drug use reported in accordance with Section 5.C.5. and/or Section 5.C.6. Amnesty will only be available for violations related to the use of alcohol or drugs in violation of the Standards and will not normally be applied for other Standards violations. Students granted amnesty may be required to participate in educational activities or meet other conditions in order to bypass application of sanctions and creation of a student conduct record. Amnesty granted in accordance with the Standards does not prevent any independent action that may be taken by any law enforcement agency, including University Police.

Virginia House Bill 1500 Summary:
Safe reporting of overdoses. Establishes an affirmative defense to prosecution of an individual for (i) simple possession of a controlled substance, marijuana, or controlled paraphernalia; (ii) intoxication in public; or (iii) the unlawful purchase, possession, or consumption of alcohol if such individual sought or obtained emergency medical attention for himself or for another individual because of a drug-related or alcohol-related overdose and if the evidence for the charge was obtained as a result of the individual seeking or obtaining emergency medical attention. The bill provides that the affirmative defense may only be invoked by an individual who (a) remains at the scene of the overdose or at any location to which he is transported for emergency medical attention until a law-enforcement officer responds to the report of an overdose or, if no law-enforcement officer is present at either the scene or the other location, cooperates with law enforcement, (b) identifies himself to the responding law-enforcement officer, and (c) cooperates, upon request, with any criminal investigation reasonably related to the drug or alcohol that resulted in the overdose. No individual may assert this affirmative defense if the emergency medical attention sought or obtained was during the execution of a search warrant or during the conduct of a lawful search or a lawful arrest.
