Portland may have become the first city on the East Coast to legalize recreational marijuana use, but residents who think this means they can light up, even in the privacy of their home, might need to think twice.

Employers will still be able to forbid their employees to use marijuana, and if that employer receives any federal funding, it is expressly prohibited from allowing any employees to use the drug.

Landlords will still be free to prohibit smoking in any apartments they rent.

And hotels say they aren’t planning to allow guests to smoke marijuana, even in rooms where cigarette smoking is allowed.

Because recreational marijuana still remains illegal at the state and federal levels, it’s unlikely that businesses and other organizations will start allowing employees, tenants or customers to smoke marijuana without consequence, and will be wary of amending any existing policy to accommodate marijuana use.
