What is the difference between substance-free and other rooms?
All student rooms, in fact all spaces in the residence halls, are non-smoking. In addition, residents and guests of “sub-free” rooms (including anyone over 21) agree to keep the room free at all times from substances that have the potential to damage their health or the community. These substances include, but may not be limited to, alcohol, tobacco products (including smokeless), illegal drugs and drug paraphernalia and illegally obtained prescription medications. More about sub-free rooms is available at http://www.housing.umich.edu/undergrad/subfree.html and in Community Living at Michigan .
