CANNABIS THE WONDER DRUG?

At a secret location in the home counties of England, 15 000 cannabis
plants are being grown quite legally. They are being bred from strains
whose names -- Hindu Kush, Skunk, Northern Lights, Gloria -- are
redolent of the Amsterdam coffee house scene. Their psychoactive seed
heads, which stand over two metres high, are carefully studied -- but
never smoked. For these plants are being cultivated as part of the
world's first commercial trial of medicinal cannabis.

The company behind the trial, GW Pharmaceuticals, based at Porton Down
Science Park in Wiltshire, has had a rather good fortnight. Firstly,
the home secretary, David Blunkett, announced on 23 October that the
government would liberalise the law concerning possession and use of
cannabis. He also indicated that he would be ready to license cannabis
for medicinal use to treat multiple sclerosis and other conditions as
soon as research trials were completed. Most commentators (including,
albeit grudgingly, the Daily Mail leader writers) seemed to approve.
On 24 October shares in GW Pharmaceuticals jumped from 13p to 108p.

Secondly, the press this week hailed cannabis as a wonder drug and a
miracle cure. Under the headline "Cannabis proves a medical miracle,"
the Observer, a newspaper not normally known for its hype, reported on
4 November that the first clinical trials of cannabis were showing
that it was "capable of transforming the lives of very sick people."

After decades of cannabis being condemned as one of the scourges of
Western society, this all seemed a bit too good to be true. Were these
claims going too far? What sort of evidence was available?

The source of the Observer's story was the BBC 1 Panorama documentary
"Cannabis from the chemist," broadcast on 4 November. The programme
looked at two separate trials -- a pilot study (n#) in East Anglia
of the effects of cannabis on the pain caused by nerve damage, and the
early stages of a much larger trial in Oxford of the effects of
cannabis on people with multiple sclerosis. The programme did not make
clear the total number involved in the latter trial -- its medical
director said in passing that he had initially seen 20 patients -- and
based its conclusions on the experiences of Sandra, Tyrone, and Jo
(n=3).

GW Pharmaceuticals is the only company in the United Kingdom that has
been given a licence to grow cannabis for medicinal use. Panorama's
journalists were the only ones to have access to those taking part in
the company's trials. Alex, who had a spinal injury, and Sandra,
Tyrone, and Jo, who all had multiple sclerosis, received daily doses
of cannabis sprayed under the tongue. They all showed remarkable
progress. Although none of them had expected to be cured, they all
experienced relief from pain. Jo, the 58 year old wife of a school
chaplain, had struggled to lift her legs before the trial but
afterwards was able to lift them 25 times. She hailed the drug's
effects as "miraculous," and her husband said, "It's not a word that
either of us would use lightly."

Dr Willy Notcutt of the East Anglian pilot study said, "The results so
far have exceeded what I dared hope for . . . we are seeing 80% of our
patients getting good quality benefit from the cannabis." Some were
getting almost total pain relief, he said. "We have seen their pain
scores go down to zero."

More dramatic claims were made by Professor Lester Grinspoon of
Harvard Medical School, one of the world's leading proponents of
medicinal cannabis. Although not involved in the trials, Grinspoon
claimed that cannabis would "eventually be used by millions of people
around the planet." Just as penicillin "was considered the wonder drug
of the 1940s," he said, cannabis "will eventually be seen as the
wonder drug of the 21st century."

On Panorama's website ( www.bbc.co.uk/panorama ) the next day, Philip
Robson, medical director of the Oxford trials, expressed concern about
newspaper "wonder drug" headlines. He said: "We have to keep this in
perspective. This seems to be a medicine which is incredibly useful
for people who haven't had very much luck with the standard medicines,
and that is really good, but I think to talk about wonder drugs and
miracle cures is way over the top."

But newspaper headline writers can hardly be blamed for their "wonder
drug" approach to the story. Panorama had given them plenty to go on,
concluding: "We could see the drug in the chemist in just two years."
Admittedly, Grinspoon's wild optimism was balanced with words of
caution from, among others, Susan Greenfield, professor of
pharmacology at Oxford University, who said: "The very term wonder
drug is very frightening." And it would have been odd if Panorama had
not embraced the opportunity to follow this historic experiment. But
the result was rather like a commercial for GW Pharmaceuticals, even
though the company's name was never mentioned.
