Is Speed cheating?

Hello everyone,

Im having a really important job interview coming up and I was wondering if I could increase my chances by taking a small amount of speed (Amphetamine) beforehand? I have a bit experience with it but im not sure if it would be a boost in this situation or I would be distracted by my own mind.

Also just as important: do you guys think it would be cheating?

should I boof it?

Love you guys/girls!
