I hope you enjoy editing here and being a Wikipedian! Please sign your messages on discussion pages using four tildes (~~~~); this will automatically insert your username and the date.

Thanks for your work on Passive Smoking. You may be interested in Wikipedia:WikiProject Medicine, more generally. To fill in citations I use Wikipedia template filling, but the Template:Cite pmid and Template:Cite doi forms that use the User:Citation bot are good alternatives. The cite journal templates they generate should allow access to the journal articles themselves, either directly or through the DOI (for those who have institutional access).
