Not at all. The majority of studies have found a notable decline in cognitive ability starting somewhere around the 800-1,200 ppm range. Due to increasing insulation/energy standards/etc, modern homes have poor air exchange and levels will often get that high or higher unless a window is opened. I have seen quite a few reports of people seeing levels exceeding 2,000 at night, and multiple studies showing that many multifamily/efficiency homes would easily get over that 1,000 ppm mark.
