A large company decides to start drug testing their employees. Let's assume that $2\%$ of the employees at the company are using drugs. The test the company uses correctly identifies a drug user $99\%$ of the time. However, it also falsely identifies someone not using drugs as a drug user $5\%$ of the time. An employee is tested and it results in a positive test. They are adamant they are not using drugs and request another test. What is the probability that the employee is a drug user if the second test also comes back positive?
