Diabetes and a Drug Test: Would Type 1 Diabetes change the time to metabolise weed?

Someone close to me is probably due for a drug test relatively soon. The minimum will probably be 1 to 2 weeks after she stopped smoking. I've read plenty about the variance in how long people take to get it out of their system but was wondering if anyone knew about the effects of Diabetes type 1 on this process?

The outcome is pretty important as the result will not just affect a job opportunity.

Also, she is a regular smoker but not 'heavy' although I don't even know what the difference is.
