Fla. Stat. § 893.13 makes it illegal for individuals to possess controlled substances unless they have legally obtained it from a licensed medical professional or have a valid prescription for the drug. Generally, a violation of this section is a third-degree Felony, which carries the potential for a maximum prison sentence of five years and a fine of $5,000. A Felony conviction also results in other repercussions, such as the loss of some civil rights.
