A passenger can face drug possession charges even when the drugs do not belong to them. For example, police may find a controlled substance during a traffic stop. If evidence suggests that a passenger knew about the drugs and could control them, prosecutors may pursue a possession charge. However, simply riding in a vehicle where police find drugs does not automatically establish possession.
When can a passenger face drug possession charges?
Florida law prohibits unauthorized actual or constructive possession of a controlled substance. Actual possession generally involves physical control of the substance. Constructive possession applies when someone knows the drugs are present and can exercise control over them without physically holding them.
For example, a passenger who has drugs in a personal bag may face a possession charge if the state can establish the required elements of possession. When police find drugs under a seat or elsewhere in a shared vehicle, prosecutors generally need evidence connecting the passenger to the substance.
How do prosecutors establish constructive possession?
Constructive possession can be harder to establish when several people occupy the same vehicle. Prosecutors must show that the passenger knew about the drugs and could exercise control over them. Mere proximity to drugs does not establish constructive possession, particularly when the passenger does not control the location where police find them.
Prosecutors may examine statements, actions and other evidence that connects a passenger to the substance. More than one person may also exercise control over the same drugs, which can support a joint possession charge.
What evidence may affect a passenger’s case?
Several types of evidence may help establish whether a passenger possessed drugs:
- Statements: Comments during a traffic stop or investigation may indicate whether the passenger knew about the drugs.
- Location: The place where officers find the substance may help show whether the passenger could control it.
- Personal belongings: Drugs in a passenger’s bag, clothing or other property may connect the passenger to the substance.
- Other evidence: Messages, fingerprints and actions may help establish knowledge or control.
What passengers should know
Simply riding in a vehicle where police find drugs does not establish possession under Florida law. The state must prove the required elements based on the evidence. When police find drugs in a shared vehicle, the distinction between proximity and control matters.
