Career Development in the Age of Legal Marijuana: Issues, Trends, and Solutions

By Christopher Pisarik and Rachel Schleier

The legal, public policy, and attitudinal landscapes of marijuana use in the United States have undergone seismic shifts during the last two decades. As of this writing, sixteen states and the District of Columbia have legalized marijuana for recreational purposes, and a total of thirty-six states have legalized it for medical purposes (Rense, 2021). Sixty-eight percent of U.S. residents support full legalization of marijuana (Brenan, 2020), and daily use of marijuana among college-aged adults is at historic levels (National Institute on Drug Abuse, 2019). Given these changes, it is essential for career development practitioners to consider how marijuana Photo By Sora Shimazaki From Pexelsuse may have an impact on the career development process.

Recent research examining the effects of marijuana sheds light on how use may affect individuals’ career development, motivation, and decision-making. Highlights of these findings, along with key workplace trends and suggested strategies for practitioners follow.

Marijuana and Career Development

Among all the stages of the career/lifespan, the emergence into adulthood is a particularly meaningful period given the psychosocial changes that occur and the foundational career tasks at hand (Arnett, 2005). Kelly and Vuolo (2018) examined role transitions marking the emergence to adulthood in a large national sample. The findings indicate that those participants who abstained from marijuana use or dabbled during emerging adulthood were significantly more likely to obtain a bachelor’s degree, secure full-time employment, and earn up to 16% higher wages than those individuals who used marijuana consistently at moderate to heavy use from 16 to 28 years of age. These findings build on previous research suggesting that marijuana use adversely affects academic performance, as well as educational and occupational attainment (Arria, et al., 2015; Fleming, et al., 2012).

Marijuana and Motivation

Career development is essentially a motivational process that requires initiative and action to realize goals. Research over the past several decades has not definitively determined marijuana use’s effects on motivation. However, Lac and Luk (2018) examined a racially diverse sample of 505 undergraduate students and found that marijuana use predicted lower levels of initiative, effort, and task persistence after accounting for race, personality type, self-efficacy, and other substance use. These results remained unchanged after a one-month follow-up.

Marijuana and Decision-Making

Career choice and transition essentially depend upon one’s ability to attend to goals, anticipate consequences, and make decisions. Research suggests that marijuana use impairs cognitive functions such as attention, executive function, problem-solving, planning, and decision-making (Crean et al., 2011). While such impairment to attention and information processing may subside after a month of abstinence, impairment to decision-making may be long term for adolescent heavy users. A plethora of factors can impact cannabis-related impairment and recovery of executive functions, however, including age of onset of smoking cannabis, years of use, and amount of regular use (Grant et al., 2003). 

Marijuana and Workplace Trends

Marijuana is currently illegal under federal law, so many employers opt for a zero-tolerance policy. However, medical marijuana use complicates workplace policies, as some states protect medical marijuana usage. While drug testing and no tolerance policies may be enforced, disciplining employees for marijuana use may be discriminatory practice under state laws. Additionally, disciplining “off the clock,” legal, recreational marijuana use can be detrimental to workplace morale (Freedman, 2020), and some states actually prohibit employers from disciplining employees for off-duty use. Yet, according to the National Safety Council (n.d.), employees who test positive for marijuana compared to those that test negative:

  • are 85% more likely to experience an injury at work
  • have 75% greater absenteeism
  • have more worker compensation and unemployment compensation claims
    and have higher turnover.

Career development professionals and their clients need to be dedicated in their efforts to stay informed about rapidly changing legalities, liabilities, and acceptable standards related to marijuana use and working life.

Considerations for Practitioners

Section C of the NCDA code of ethics (NCDA 2015) calls upon career development practitioners to gain knowledge of current issues through continuing education and professional involvement. Inconsistent and equivocal research findings regarding the impact of marijuana use can be confusing, so it is incumbent upon career practitioners to acquire and maintain knowledge and competency to help clients navigate these complex issues. There are many reliable knowledge outlets to draw upon to stay informed. For example, NAADAC (National Association for Alcoholism and Drug Abuse Counselors) and SAMHSA (Substance Abuse & Mental Health Services Administration) provide accessible, updated literature, data, and resources regarding the effects of drug use and policy around substance use in the workplace. NECA (National Employment Counseling Association) also offers resources for employers, employees, and career counselors and coaches.

Assessments are additional tools to help practitioners and clients understand if marijuana use is an impediment to their career development process and mental health. Assessment can be formal (e.g., administration of standardized tests), as well as informal. For example, career practitioners might:

  • assess clients’ cannabis use upon initial intake with questions on an intake form, specifically seeking information regarding use-related problems
  • listen intently for indications of issues with marijuana during discussions of concerns and barriers related to career goals
  • watch for marijuana use as a factor that emerges when using facilitated narrative techniques such as life-lines, career autobiographies, career construction interviews, and career genograms.

The NCDA code of ethics (2015) states that career professionals must practice within the boundaries of their competence. Therefore, a referral to a mental health professional with substance use counseling experience and competency in substance use disorder assessments may be warranted.

Given the rapid change in marijuana laws and practices, career practitioners, job seekers, and clients in career transition need to stay informed about workplace policies and regulations regarding marijuana use at work and understand the potential implications of use on career development.
