L.L. v. State, 189 So. 3d 252

Juvenile L.L. was charged with simple possession of cannabis; at trial Officer Joseph Muñecas testified he identified the substance as marijuana by sight and smell.
Officer Muñecas approached a parked vehicle, smelled a "strong odor of marijuana," L.L. admitted possession and produced a bag; the officer identified the bag contents and a rolled cigarette as marijuana.
L.L. sought a Daubert hearing to challenge the officer's opinion testimony; the trial court conducted the foundation colloquy during trial and admitted the officer's identification over objections.
On cross-examination the officer said his opinion rested on personal sensory perception and field experience, not scientific methodology.
The trial court expressed doubts about Daubert criteria but admitted the testimony as consistent with pre-2013 Florida practice allowing experience-based identifications.
On appeal the central question was whether such experience-based sight/smell identifications are admissible as lay opinion under Fla. Stat. § 90.701 or must satisfy the Daubert/§ 90.702 expert standards.

Issue	Plaintiff's Argument (L.L.)	Defendant's Argument (State)	Held
Whether the officer's identification must meet Daubert/§ 90.702 expert reliability	Officer: identification required specialized methodology and should satisfy Daubert reliability factors	State: Daubert factors are flexible and identification is permissible based on experience; alternatively analyze under lay-opinion rule	Court: Daubert/§ 90.702 not applicable; analyze under lay-opinion § 90.701; testimony admissible as lay opinion
Whether identifying marijuana by sight/smell requires "specialized knowledge" excluding it from lay opinion under § 90.701	Officer's experience is specialized and thus should be treated as expert opinion	State: identification is based on personal perception and everyday reasoning, not specialized expert methodology	Court: identification rested on firsthand perception and everyday reasoning — not expert-level methodology — so it fits § 90.701
Whether Officer Muñecas had sufficient personal knowledge to support lay opinion	L.L.: officer did not employ scientific method or show reliability metrics, so identification is unreliable	State: officer had years of field experience and sensory familiarity sufficient to support lay opinion; cross-examination guards reliability	Court: officer had sufficient firsthand familiarity; court did not abuse discretion admitting testimony
