Which drug was most commonly detected in the LAPD DRE Field Study?

The drug most commonly detected in the LAPD DRE Field Study is PCP (phencyclidine). PCP is classified as a dissociative anesthetic, and it has unique pharmacological effects that can significantly impair perception, cognition, and motor coordination. This substance often leads to striking symptoms that are easily recognized during drug evaluations, including hallucinations, agitation, and disorientation.

The prevalence of PCP in the study can be attributed to its specific behavioral and physiological effects that align with the criteria used for drug recognition evaluations. Additionally, PCP usage has been linked to various dangerous behaviors, making its detection critical for law enforcement and public safety during drug assessments.

In comparison, while cocaine, heroin, and THC (the active component of cannabis) are also commonly encountered in drug-related cases, the frequency of their detection may not match that of PCP in this specific study context. Understanding the characteristics and risks associated with PCP emphasizes its significance in drug recognition and evaluation processes.
