Intoxication vs. Impairment: What Students, Interns, Employees, and Employers Need to Know About Cannabis Use

When discussing cannabis, it’s crucial to understand the difference between intoxication and impairment.
Understanding Intoxication and Impairment
Intoxication refers to the period when someone feels “high.” In contrast, impairment relates to the ability to think clearly, make decisions, and act safely.
The tricky part is that impairment can linger long after the high has faded. A student, intern, or employee might feel normal and appear fine, but their focus, reaction time, judgment, and coordination could still be affected. In classrooms, labs, clinical placements, or internships, recognizing this difference is vital because impairment isn’t always visible.

The Effects of Cannabis on Cognitive Function
Cannabis, available today in many forms, can impact attention, memory, reaction speed, and executive functioning. Research indicates that these effects can persist beyond the initial high, especially with frequent or high-dose THC use.
Over time, individuals may not feel as “high” as they once did, but their cognitive skills could still be compromised. This means that cannabis use outside of class, work, or clinical hours can still affect performance and safety, even if the person believes they are ready to learn, practice, or perform.
The Complexity of Drug Testing
Drug testing adds another layer of complexity to this issue. Tests do not measure impairment; they only detect exposure.
Urine and hair tests reveal past use, not current ability to function. Oral fluid and breath tests can indicate more recent use, but even these do not confirm whether a student or intern can safely engage in learning, lab work, or professional duties.

Assessing Readiness for Duty
Assessing readiness or fitness for duty in these contexts requires considering various factors. These include the role, timing of use, the testing method, observable signs of impairment, and the overall safety or learning environment.
Clear policies, education, and informed interpretation of results are essential for supporting both safety and success.
Navigating Responsibilities
Understanding the difference between intoxication and impairment is not merely a compliance issue. It’s about ensuring the safety of students, interns, and educators while helping young people navigate their responsibilities effectively.
The “high” may fade, but impairment can linger. Recognizing this distinction is crucial in learning, work, and life.
Conclusion
In conclusion, the implications of cannabis use extend beyond the immediate effects of intoxication. Impairment can have lasting consequences that affect performance in academic and professional settings.
By fostering awareness and understanding, we can create safer environments for everyone involved.
