Butt Receptacle

If emptying the trash cans cigarette butt cause cancer or harm your health in any way?
I work part-time jobs during night for a cleaning company. Clean a large construction company and asked that the empty cigarette butt receptacles for them. I chose to be a non-smoker and I am grateful, because I know how difficult it is to stop smoking. Or if I do not want any second. The vacuum can be at work like that. http://www.barcoproducts.com/images/upload/items/OP-0603.jpg Just wondering what the possible effects might be either if I have to take certain precautions when doing this.
I worked in an agency to clean me. I never had problems with the cans. that will not give you cancer. You really need to be careful with cleaning products, rather than cans.
