Detection time of a half gram of medical, smoked over the course of 5 days?

I quit smoking so I could look for a new job, but 2 months in I gave up and started up again. 5 days later unexpected circumstances arose and now I am in desperate need of a new job, and to cleanse my system.

Although I smoked for 5 days straight, the amount was very conservative. Here is the breakdown:

Day 1: 0.15g (3 one hitters)
Day 2: 0.15g (3 one hitters)
Day 3: 0.1g (2 one hitters)
Day 4: 0.05g (1 one hitter)
Day 5: 0.05g (1 one hitter)

It is also worth noting that I have relatively low body fat, and I am relatively active (lift every other day).

Would I be considered a frequent smoker since I smoked for 5 days straight, even if the total amount was only 0.5g? Or would I be considered an occasional smoker since the amount was so small? In my case, how long would THC be detectable in my urine in a standard lab test? Chances are if I get the job I'm pursuing, I will be testing at LabCorp.

Also, what would be the best way for me to speed up the detox process?

Only periodic testing with a THC test kit can give you that answer. When testing yourself, be sure to use the first void of the day.

The only proven way to expedite THC-unloading is time and fat-burning exercise.
