Generating contour lines from LIDAR data - resolution question

I have a LIDAR dataset with point spacing of 3.5 feet.
What is realistically the highest resolution of elevation contour that i can generate with this data?
I generated 1 foot contours, but am i interpolating too much by going finer than the source data?
Should i stick to a minimum of 3.5 feet?
Thank you!
