I have been given to understand that some particulate matter present as
residue on clothing, fabric or other surfaces resulting from prior
exposure to tobacco smoke creates respiratory problems in infants.  I am
curious as to how much exposure results when the baby does not co-sleep,
versus when it does.  If more exposure occurs when co-sleeping, then
why?  Can this be controlled by the user?

Is there any research to indicate whether smokers breastfeed longer and
more exclusively if they co-sleep?  If it were found to be true, how
would it affect the risk over the long term?

Have the researchers controlled for smoking occurring in the sleeping
room at any time during the day, whether it is the "parents" room or the
"baby's" room?  This is highly controllable, and if it were teased out
as a variable and shown to be important, it would be good to know.

Is the sleep of smokers affected, and if so, is this a variable?  Also,
is the rate of SIDS in smoking, bf, co-sleepers variable with the dosage
of tobacco taken daily, or by time of day?

Do smokers tend to have a higher incidence of co-variables such as
alcohol consumption, warmer household temperatures, etc.?  How might
these other variables affect co-sleeping?

Have all these questions been addressed with marijuana smoke?
