What are Cannabinoids?

Cannabinoids are a group of chemical compounds naturally found in the cannabis plant. Among the most well-known are THC (tetrahydrocannabinol), Delta-9 THC, and CBD (cannabidiol). THC and Delta-9 are psychoactive, meaning they produce the “high” associated with marijuana use, while CBD is non-intoxicating and used primarily for therapeutic or wellness purposes. These substances interact with the body’s endocannabinoid system, affecting mood, perception, appetite, and pain signaling.

Cannabinoids appear in many forms depending on the product:

Plant material: dried green/brown flower/bud for smoking or vaporizing
Concentrates: oils, waxes, shatter, resins used in vape cartridges or dab rigs
Edibles: gummies, baked goods, beverages
Tinctures and oils: droppers taken orally or sublingually
Topicals: lotions, balms (typically CBD-focused)
Capsules or softgels: regulated CBD or medicinal cannabis products

THC/Delta-9 are typically inhaled or consumed orally. CBD products are widely available in non-intoxicating formulations and often marketed for anxiety, pain, or sleep support.

Medicinal Use: Certain forms of THC and CBD are legally prescribed or sold through regulated medical marijuana programs for conditions such as chronic pain, nausea, seizures, and muscle spasms. FDA-approved CBD medication (Epidiolex) is used for rare seizure disorders.

Recreational Use: THC and Delta-9 are widely used recreationally for their euphoric, relaxing, or sensory-enhancing effects. Potency varies significantly depending on strain, extraction method, and product type.

Effects:

Altered perception and changes in sensory awareness
Relaxation and reduced anxiety (varies by user)
Increased appetite
Impaired short-term memory
Slowed reaction time and reduced coordination
Euphoria or enhanced mood
Dry mouth and red eyes
Potential anxiety or paranoia at higher doses
Impaired decision-making
Sedation or drowsiness (especially with high-THC or some CBD formulations)

Legal Status:

The legal status of cannabinoids varies widely across the U.S. and internationally. Delta-9 THC remains federally classified as a Schedule I controlled substance, meaning it is illegal at the federal level but permitted for medical or recreational use in many states. CBD, when derived from hemp and containing less than 0.3% THC, is federally legal, but products remain largely unregulated and can still trigger positive THC results due to cross-contamination or mislabeling.

For point-of-care toxicology testing programs—including workplaces, treatment settings, and government-run monitoring—THC continues to be one of the most commonly screened drug classes. Even in states where cannabis is legal, employers and federal agencies may enforce cannabis-free policies, particularly in safety-sensitive environments. Because CBD can cause false positives or unexpected THC detection, many testing programs include confirmatory lab testing to differentiate legal hemp-derived CBD from illicit THC use.

POC programs must also navigate changing legislation, employee protections in certain states, and federal regulations that still mandate THC testing for specific industries (e.g., DOT). Clear policies and consistent confirmatory procedures help ensure fairness, compliance, and defensibility of testing results.
