Just a thought, this, but cannabis is officially illegal, and so it is
difficult to produce quality research on its addictive properties in humans
without crossing ethical barriers. Therefore any studies you find (there
probably were some in the sixties) will be anecdotal and retrospective rather
than prospective, as in the kind of addictive properties trials that might be
done with, say, a new antidepressant. Also remember that sometimes, a paper
may be biased in its outlook to reflect the political mood of the time.
