NOT YOUR MOTHER'S REEFER

The 18th-century poet Alexander Pope was a keen student of human
nature, and often delivered bits of timeless wisdom in
memory-friendly rhyming couplets.

One that opinion writers in particular should take to heart from his
Essay on Criticism is: "A little learning is a dangerous thing; drink
deep, or taste not the Pierian spring: there shallow draughts
intoxicate the brain, and drinking largely sobers us again."

The words "intoxicate the brain" bring to mind the Post's 2007
editorial on marijuana, enunciated in response to evidence that
Canada's marijuana consumption was the highest in the industrialized
world: "What is really remarkable about Canada's status as a cannabis
capital is that if you were to set out looking for reasons to worry
about it . you would have an awfully hard time finding them.
Legalizing pot makes sense."

What was the editorial board smoking when these words were written?
In fact, one would not "have an awfully hard time" finding reasons to
worry if one were actually open to finding them. In fact, it would be
quite easy. Legalizing pot "makes sense" only to those who have a
"little learning" on the changed nature of cannabis over the last 25 years.

In 1997, the liberal U. K. newspaper The Independent launched a
campaign to decriminalize marijuana. Encouraged, 16,000 pro-cannabis
activists marched to London's Hyde Park, a show of strength credited
with the government's subsequent downgrading of cannabis' status as a
legally restricted substance.

Since then, "skunk," as Britons call the hybrid form of cannabis in
current usage, has offered users a 25-fold increase in
tetrahydrocannabinol (THC), cannabis' psychoactive ingredient. The
mental and physical effects of this chemical change have been dramatic.

In March 2007, The Lancet, Britain's leading medical journal,
declared cannabis to be

more dangerous and addictive than LSD and Ecstasy. About the same
time, Professor Colin Blakemore, chief of the Medical Research
Council (and in 1997, the moral authority behind The Independent's
liberalization campaign) unequivocally reversed his
cannabis-friendliness: "The link between cannabis and psychosis is
quite clear now; it wasn't 10 years ago."

As a result, The Independent last year offered its readership a
fulsome apology: "If only we had known then what we can reveal today ."

Psychiatry professor Robin Murray of London's Institute of Psychiatry
estimates that cannabis usage is causally linked to a full 10% of the
U. K.'s 250,000 bipolar patients: "The number of people taking
cannabis may not be rising, but what people are

taking is much more powerful . we may see more people getting ill as
a consequence."

Indeed, just this past February, the European Respiratory Journal
reported on a New Zealand study indicating that long term cannabis
use increases the annual risk of lung cancer in young adults by 8%
for every year of use.

In order to better understand this sea change in experts' opinions
and how it applies to Canada, I spoke with Ontariobased addiction
counsellor and treatment/prevention specialist Don Smyth. As in
Britain, Smyth explained, kids here are smoking a hybrid
Middle-Eastern/ Asian variety of cannabis that is far more intense
and addictive than past varieties.

Here, skunk is known as "bud," because, as one young adolescent in
Smyth's practice told his 70s-minded mother: "Mom, we don't smoke the
leaves. We throw the leaves out. We just smoke the buds."

In 1970, pot contained 1% THC. Bud contains 20% THC. Imagine a glass
of wine or beer with a similarly proportioned alcohol content and
consider the "rush" it would provide.

Thus, Smyth and others well-informed on the subject claim it is
misleading to identify this super-strength cannabis as a "soft" drug.
"Pot or weed essentially no longer exists," Smyth says, grimly
concluding, "I am absolutely haunted by the irreparable harms this
so-called innocuous drug has brought to the lives of [young users]."

British politicians have "drunk large" of the evidence, and reversed
their position of moral indulgence. Two weeks ago, the Home Office in
the U. K. announced: "Cannabis will be reclassified as a Class B
drug, sending a strong message that the drug is harmful."

The verdict on the new marijuana is in, and it's "guilty." I would
therefore respectfully ask the Post to reconsider its editorial
stance on the legalization of "pot," clearly a superannuated
description of cannabis today, and in future commentary on this
issue, so critical to our youth's health, exercise a little more
intellectual-- ahem-- sobriety.
