Is it a bad practice to have a cfc access a session variable? Should the
session variable be passed in as an argument instead?

Best practice is to pass in the session variable. There can be issues
with calling a persistent scope directly within a CFC, typically around
application performance and proper garbage collection.

In general, yes. The exceptions are if you have a method specifically meant
to encapsulate access session scope so that other methods in the object can
get to that data (i.e. a getCurrentUser() method in a UserService), or if
you create a dedicated SessionProxy object that other objects use to
I've got an example of a Session Facade (or Session Proxy?) on my site:

I can vouch for Adrian's article, though. When I first started working
with Session Facades in Mach-II, the post he linked to below went a long
way in helping me understand them.
