Trending successes in the quest for the legalization of medical marijuana screeched to a halt today, stopped by our nation's citizens' right to be safe in hospitals, highways, and other professional endeavors. The Colorado Supreme Court, in Coats v. Dish Network, affirmed an employment related firing of a Dish Network employee who tested positive for marijuana, in violation of the company's zero tolerance drug free work place rules.Mr. Coats a quadriplegic, wheelchair bound his teen years. Current medical conditions cause continued suffering, warranting in home legal medical marijuana use consistent with his lawfully secured pot license and Colorado State law. Coats, however, secured a job as a telephone customer service representative (not even a driver servicing homes), who tested positive for THC in a random Dish Network employment related drug test. He was summarily fired.Coats filed suit, claiming his registration as a medical marijuana patient excused his legal, private, medical-based drug use under Colorado State law. He claimed Colorado's employment related statute protected his "at least lawful" medical marijuana use. The Colorado Supreme Court rejected this claim.Dish network, similar to many other employers across the country, has a zero tolerance drug testing policy. The language of the policy states that any drug use must be "lawful activity". This means you must have a prescription for a legal medication identified as such under federal DEA regulations. Pot is not one of them. The Colorado Supreme Court determined that because medical marijuana is a state right and not a federal "lawful" activity, Dish Network properly terminated Coats for violating its legal work place rule.A random employment relate drug test in many companies around the country - in pot legal states or not - will, typically, reveal personal, medicinal or not, marijuana use. Employment termination for violating companies' drug policy happens every day. The issue here was Coats' allegations of wrongful termination stemmed from his state based lawful activities off the premises. The Colorado Supreme Court rightly rejected this argument.The court reviewed the basic premise that under federal law marijuana use and possession is still not lawful. The court contrasted this premise with Colorado's medical marijuana laws that recognize medical marijuana use as lawful. The court concluded, however, that the supremacy of federal law still makes any medical marijuana use not "lawful".Colorado's employment related termination statute had not been amended since its legislature created the medical marijuana laws. Consequently, the employment related statute does not identify lawful activity to be that under state or federal law. This a huge issue.Coats had to acknowledge the federal Controlled Substance Act prohibits medical marijuana use, (identifying it as a Schedule I narcotic having no medical excepted use, a high risk of abuse, and a lack of excepted safety). The court referenced federal allowance of pot use in research projects, but no exceptions for medicinal or personal use. Clinging to the Supremacy Clause, the Colorado Supreme Court concluded the because of the federal proscription of medical marijuana, Coats' medical marijuana use was unlawful under federal law, and, therefore unlawful under Colorado's employment related termination statutes. Unless state law is explicitly altered to preclude termination based upon state law and not general "lawful activity", Federal law controls in this area of employment related litigation.This a clear public policy statement. Coats is the perfect plaintiff. His medical condition is clear and his does not work in public safety position. Nonetheless, the court's rejection of the state based legal pot defense, enforcing a very vanilla drug free work rule utilized by a national company against a quadriplegic, is a clear message -- companies that want a drug free work place can have one and our nation's citizens can fee safe utilizing those companies.The policy decision and practical implications of this case nationwide and in Pennsylvaniare enormous. This interpretation of an employment related statute is congruent with Pennsylvania's 26 licensing schemes addressing illegal conduct. Currently, any unlawful conduct (testing positive for marijuana use) is already a basis for disciplinary action under various boards' licensing scheme.The legalization of marijuana in Pennsylvania would necessarily require a public policy decision to alter each of these licensing schemes and their enforcement mechanisms. It is doubtful such would occur because the Pennsylvania's professional boards want Pennsylvania's citizens to know the professionals they rely upon in every day life are drug-free and not impaired by the use of an illegal Schedule I controlled substance.Said another way, Pennsylvania's licensing boards want competent, unimpaired professionals in hospitals, nursing homes, medical offices, hospices, builders, architects, accountants, and the like helping and professionally serving Pennsylvania's residents. Allowing the medical use of marijuana for medical registered non-professionals may proceed. But this will be in conflict with many other citizens rights to receive unimpaired professional services. Employers' and drug-free citizens' rights will trump the minority who wish to get high on pot.Conservative state legislatures will continue to enforce employers' right to have a drug-free workplace. This will allow employers to utilize the federal policy on pot to insure a safe workplace staffed by unimpaired, drug-free workers. Whether it be on our nation's highways, union workers building bridges, buildings, or professionals caring for our nation's sick, states will continue to demand lawful, unimpaired workers staffing these jobs. Employers will choose unimpaired, drug-free workers who choose professions over drug use.The legalization of pot should not and will not change this broader policy consideration. The wants of the few will not out-weigh the needs of the many when balanced against public safety.
