Would it be unwise for me to start smoking weed again?

I started working for a commercial cleaning company almost two years ago. I got promoted to a pod leader about 5 months ago. I work with an autistic man, and I have to make sure he's doing everything right, and that we are keeping the clients happy. Well, I haven't smoked in like 5 years, and I wanted to start again. I was looking at the Facebook page of the company I work for, and they are hiring another pod leader. As i was reading the required qualifications, it said "must pass drug test to include random drug testing (THC not in included)". I haven't read the employer handbook since I started working for the company, but I think it says the same thing. What do you think? It would really suck if I started smoking again, and they decide to randomly drug test me, and I fail, and lose my job. Do you think it would be unwise for me to start smoking again?
