Withdrawal: Presence and severity of characteristic withdrawal
symptoms.

Reinforcement: A measure of the substance's ability, in human and animal
tests, to get users to take it again and again, and in preference to other
substances.

Tolerance: How much of the substance is needed to satisfy increasing
cravings for it, and the level of stable need that is eventually reached.

Dependence: How difficult it is for the user to quit, the relapse rate,
the percentage of people who eventually become dependent, the rating users give
their own need for the substance and the degree to which the substance will be
used in the face of evidence that it causes harm.

Intoxication: Though not usually counted as a measure of addiction in
itself, the level of intoxication is associated with addiction and increases
the personal and social damage a substance may do.

on Whose Criteria You Use."

Caffeine definately has a higher dependance than MJ, atleast in my experiences. In fact, I very rarely drink pop anymore.
