Does get_tobacco contain an ID field? If you're comparing two sets of ID's, my
CF_Venn tag can do that:
CF_Venn ListA="#ValueList(Contents.ContentsID)#"
ListB="#ValueList(get_tobacco.theID)#" AandB="matches">
The heart of the relevant code is simply:
<cfset AandB = "">
<cfloop list="#ListA#" index="Elt">
<cfif ListFindNoCase(ListB,Elt)>
<cfset AandB = ListAppend(AandB,Elt)>
</cfif>
</cfloop>
