Important information for camps - and all employers.
Even though on January 1, 2014, some states, including Colorado, have made the purchasing, possessing, and using of marijuana legal under state law - it is still generally illegal under federal law. And, importantly, even in these states, employers have the legal right to prohibit marijuana use by its employees both on AND off the job. Read More. 
With the results of the November 2012 elections, eighteen states and the District of Columbia have now enacted laws to legalize medical marijuana (See the list .). Also in November 2012, voters in Colorado and Washington took the movement further, endorsing the sale of marijuana without a prescription for recreational purposes (Both states are establishing regulatory regimens for pot similar to alcohol). At the same time, however, the federal Controlled Substances Act (CSA) makes the use, possession, etc., of marijuana (and other Schedule I drugs) generally illegal. Under the supremacy clause of the U.S. Constitution, the federal CSA preempts conflicting state laws.

- If you are inclined to accommodate the use of medical marijuana on or off your premises by one of your staff, consider the consequences. Even if you choose to allow such use, consider that there is a well-documented body of research identifying that use of marijuana impairs an individual’s ability to function — and that impairment would logically extend to many traditional camp activities (for example, driving vehicles or running a zip line or challenge course) and the supervision of co-workers and campers.

- Confer with your legal counsel to understand your state’s medical marijuana laws, and state anti-discrimination, disability rights, or other laws, should you be confronted with prospective employees or campers — or existing employees — using or seeking to use medical marijuana.
