All good advice except to add:
If there are no fuel-combusting appliances (stove, heater, fireplace, etc.) there is no need for a CO detector. But a reliable and tested smoke detector is still needed.
CO concentrations at toxic levels are not produced by cigarettes except to the smoker inhaling them. They are too diluted by room air to be life-threatening, although the other components (carcinogens) remain high enough to affect exposed non-smokers.
A DO NOT for all time – DO NOT use charcoal (or any other fueled) BBQ appliance indoors. These are sometimes use as alternative heat sources where incomes are low and other heat sources are cutoff.
