You are also assuming that the subjects were not addicted. Maybe
they were and maybe they weren't. The study only says that they
all failed to get off the drugs when given the opportunity.

Yes. Effectiveness and addiction are separate issues. There's nothing
in the report that allows anyone to exclude the possibility that those
given Ritalin became addicted (under any definition of the word) to it.

You tried to draw conclusions about ritalin not being addictive.
The opposite conclusion is more likely.

I agree. There's *nothing* to indicate that the users weren't addicted,
and, while the fact they (all!) chose to continue taking it isn't proof
of addiction, it, at least, can be used to support that conclusion.
