When a Worker uses a Cannabis / Marijuana substance, such as Cannabis / Marijuana Flower, that contains Tetrahydrocannabinolic acid (THCA or 2-COOH-THC) which when heated causes a decarboxylation process to convert THCA to the psychoactive cannabinoid Tetrahydrocannabinol / (−)-trans-Δ⁹-tetrahydrocannabinol (THC), the Worker may suffer from THC related cognitive function impairment in their executive functions of basic motor speed, memory, and attention.
Assessment of “in the moment” motor speed, memory, and attention are the core components of a Quick Test™ assessment.
Motor Speed or Reaction Time is the lapse in time between the presentation of stimulus and a Worker’s response. For example, a Person is walking towards a forklift and the Worker operating the forklift safely stops the forklift.
Memory or Working Memory is the ability of a Worker to hold and manipulate information and then remember it following a short delay. For example, a Physician provides verbal or written instructions to a Registered Nurse and then the Registered Nurse is able to remember and act on those instructions in the work area.
Attention is the process of a Worker selectively attending to one aspect of the work environment while ignoring other stimuli. For example, a Worker is operating heavy equipment in the work area and is able to remain focused on the operation of their heavy equipment when other stimuli are present in the work area.
If a Worker has recently used a Cannabis / Marijuana substance containing THC, they may suffer from deficits in the aspects of planning and decision making with regard to response speed, accuracy, latency, and a decreased ability to apply higher order executive functions related to cognitive processing including the Worker’s inability to articulate that they are suffering from cognitive function impairment.
A Worker that has recently used a Cannabis / Marijuana substance containing THC may not be able to state that they are impaired however they may be able to describe their coping mechanisms related to cognitive function impairment. Examples of these coping mechanisms can include Worker statements such as,
“I leave more space between myself and other people when I am following them.”
(Impairment or latency of response in motor speed),
“I try to focus on one task at a time.”
(Impairment of working memory and latency in executive functions related to task completion),
and “I avoid busy areas and locations.”
(Impairment or latency of concentration and attention).
