Reference Librarian comments

This is a good example of MEDLINE searching, where you were learning as you go, fussing around with sets, and putting it all together finally at the end. I'm glad you used MeSH terms (the Medical Subject Headings), and you used subheadings (the "adverse effects," "poisoning," etc.) and the LIMITS tricks. A fine job. Congrats.

We have two other online resources which come to mind. They are:

PsycInfo

and

Project Cork

If you're still interested in this topic, and if you needed more references, there would certainly be more available, in those resources. And of course there are books available. An example:
