Under Florida state law, there are two different types of drug possession: actual possession and constructive possession. With actual possession, the defendant allegedly had the heroin — or another illegal substance — on their person. It could be in their hands, in their pockets, or somewhere else on their body. Regardless, actual possession is physical possession.
With constructive possession, the defendant does not have actual physical possession of the heroin, but instead has both knowledge of and control over the substance. As an example, a person who is found to have heroin in the glove box of their vehicle may be charged with constructive possession. In Florida, knowledge is a required element in a constructive possession case.
