Possession of Contraband by a Federal Prisoner is a criminal offense that occurs when a person who is incarcerated in a federal prison is found in possession of items that are not allowed in the facility. These items are classified as contraband, and possession of them is prohibited by federal law. Examples of contraband that are typically not allowed in federal prisons include, but are not limited to, weapons, drugs, alcohol, cell phones, and electronic devices. There are two types of Possession of Contraband by a Federal Prisoner: actual possession and constructive possession. Actual possession occurs when the contraband is found on the individual or in their immediate possession. Constructive possession occurs when the individual has knowledge of the contraband, or has control over its whereabouts, even if it is not in their physical possession. In both cases, possession of contraband by a federal prisoner is a serious offense that can lead to severe consequences. Depending on the severity of the case, penalties can range from a fine to a lengthy prison sentence.
