Does Cisco drug test?

No, Cisco does not routinely drug test its employees. However, if you work with a federal customer of Cisco, you may be asked to take a drug test, at the discretion of that customer.

Cisco employees are not permitted to use, possess, sell, transfer, manufacture, distribute, or be under the influence of illegal drugs on Cisco-owned or leased property, during working hours, while using company property, or while otherwise representing the company.
