What's the name used for statements which can be used to argue for
or against a point, which seam to conflict but infact are not
incompatible?
Examples include: "The majority of cannabis users do not progress
to harder drugs" -- "The majority of heroin users began as cannabis
users" [...]

Subcontraries. Look up the "square of opposition" in traditional logic.
