Society does not support
heroin as pain reliever
Back in the summer of
1981, the Canadian Cancer
Society rejected a request to
join a group lobbying for the
legal acceptance of heroin as
a pain reliever for ter-
minally ill cancer patients.
The Society's position was
that a review of existing
information on heroin did not
support its use over other
already available legal
drugs such as morphine.
Unfortunately, the
Society's stand was quoted
out of context by a physician
writing for The Globe and
Mail. ("The Doctor Game",
April 15, 1982). This resulted
in numerous letters and
phone calls from members of
an irate public insisting_ona

have failed to turn up any

heroin. If administered
properly, alone and -or in
combination with other
drugs, morphine is as
fective as heroin. It is also
less addictive. It° is in-

Health Organization is
