TAKING A POT SHOT AT THE DANGERS, IF ANY, OF CANNABIS

Several countries are legalizing or decriminalizing the use of marijuana. On
Thursday, cannabis was reclassified as a class C drug in the UK, alongside
tranquillizers and steroids. But does anyone really know what the dangers of
smoking dope are?

Steve, 25, Jamie, 23, and Amit, 30, all liked, or like, a smoke. Steve tried
cannabis at school and was smoking 10 to 15 joints every evening by the time
he was at college. He lost his job and started behaving erratically. One
night, drunk and stoned in a club, he ate a lump of hashish resin and woke
up hearing voices. He is still being treated for schizophrenia. For several
years Jamie had smoked 20 joints, often of powerful skunk, a week. He holds
down a well-paying office job and says that he has no problems with
motivation or concentration. He says he has never suffered any adverse
effects, let alone mental health issues, and describes his consumption as a
"positive lifestyle choice."

Amit smoked 15 joints a day for six years. "My life was like something from
The Office," he said earlier this month. "I had an undercurrent of
depression throughout that time. Without cannabis, it would have been much
worse."

Amit has a new job and stopped using cannabis six months ago. But he admits
it was hard to break his habit.

"There is no doubt I was addicted," he said. All three men were heavy users.
According to the Independent Drugs Monitoring Group, a typical user consumes
more than seven grams (a quarter of an ounce) of average-strength cannabis a
week.

This year an estimated one in 10 Britons aged between 16 and 59 -- about 3.3
million people -- will use the drug. Few of them will smoke as much as
Steve, Jamie and Amit ever did. Instead it will be a quiet spliff on a park
bench outside school, or with coffee after a dinner party, or while watching
a video on a Sunday evening when the children have gone to bed. The amount
of cannabis smoked in the UK is unprecedented. But for an activity that has
such mass appeal -- one in four 15 to 24-year-olds smoked it last year,
according to the British Crime Survey -- very little is known about the
effects of such broad consumption on people, on health, on society. Cannabis
was on Thursday reclassified from a class B to a class C drug -- putting it
on the same level as steroids and tranquillizers. The effect of the change,
and the police guidelines issued along with it, will make it extremely
unlikely that anyone consuming cannabis in private will be arrested. Smoking
pot in your own home will, in practical terms at least, be legal. Offend
repeatedly or smoke in a public place or outside a school and the
consequences could be severe, however. Under-18s, say the guidelines, should
be arrested, although in reality it is unlikely that the police will always
follow the law to the letter. Possession can still result in a two-year
prison sentence. There are also increased penalties for dealing.

The changes, recommended first in a report by the Police Foundation, a
council of scientific experts and the Commons Home Affairs Select Committee,
regularize the reality of the enforcement of soft drugs law. In much of the
country, police rarely arrest and prosecute "personal users." None the less,
in 2000 there were 70,000 convictions for possession of cannabis. The
changes are controversial. Some criticize any move to liberalize drug laws,
others criticize the confusion surrounding the new policy and many say the
changes don't go far enough.

The debate grew more heated earlier this month when new research by leading
psychiatrists pointed to a strong link between mental illness and cannabis
use.

Robin Murray, a psychiatrist at the Maudsley hospital in south London,
published findings stating that cannabis both increases the risk of serious
mental illness and exacerbates existing psychotic conditions. Murray's
conclusions were controversial. His research was not published in time to be
presented to the council of experts consulted by the Home Office when it
decided to go ahead with the declassification. Critics of Home Secretary
David Blunkett's decision seized on it as evidence that the government's
drugs policy is, in the words of the Daily Mail's Melanie Phillips,
"reckless." The opposition Conservative Party accused the government of
"mixed messages" and vowed to reverse the move.

psychosis In fact, the situation is more nuanced. Murray cited research in
Sweden and Holland that confirmed the link between cannabis and psychosis.
Research at Yale Medical School showed that tetrahydrocannabinol (THC) --
the active ingredient in cannabis -- can produce a psychotic reaction. The
studies confirmed that no one could sensibly say that cannabis was
"harmless." However, they did not prove that cannabis was necessarily
dangerous for everyone. According to Paddy Power, a consultant psychiatrist
with the Lambeth Early Onset Service in south London, 70 percent of the 170
people referred to the clinic each year take cannabis.

"A proportion of the population is certainly at risk of psychosis from heavy
use of cannabis, but they are a minority and it is possible that they are
already at risk of psychosis for a variety of other factors," he said. And,
to many, this is key. Power likens the connection between cannabis and
psychosis to the link between cigarette smoking and lung cancer and heart
disease. "It does not mean one leads inevitably to the other. The more you
do, the more you are at risk," he said.

Steve, quoted above, is certain that cannabis triggered his psychosis.
Trying cannabis since developing his condition set off an immediate
reaction. "It made me feel instantly crazy," he said. "It was like turning
on a switch." But Steve may have been vulnerable already, backing up the
general consensus that cannabis can make mental illness worse or increase
the risk, but does not cause it. Steve's father, Terry Hammond, now works
for the mental health charity Rethink. He agrees that, though cannabis had
"hurled [his son] over the edge, Steve had previously showed signs of
vulnerability."

But no one knows how many might be vulnerable. Some talk of as many as one
in seven or in 10. Yet Les Iversen, professor of pharmacology at Oxford and
a House of Lords adviser on drugs misuse, said the fraction was "tiny."
Harry Shapiro, of the independent research centre Drugscope, referred to a
"handful out of millions" being affected.

The issue of psychosis touches on many key debates within the broader
argument over the legalization of cannabis and, more generally, society's
approach to other drugs.

Is the risk of exposing a vulnerable minority to possible psychosis
outweighed by the harm done to society by criminalizing millions of people
who safely enjoy cannabis? Is it even correct to lump cannabis with other
controlled drugs such as heroin or crack that are far more dangerous to
individuals and to society? What about the differing strengths of cannabis?
What would happen if cannabis supply was controlled by the government? Is it
not irrational to focus on cannabis when alcohol, almost all health
professionals agree, is a far more harmful drug and is misused far more
widely?

Despite decades of debate, there is little clear consensus over the way
forward. Peter Coker, who has worked with drug users for nearly 20 years and
currently runs the National Drug Prevention Alliance, opposes the
reclassification, let alone any further liberalization.

"Blunkett thought that, if he gave this concession to the liberalizing
lobby, it would be satisfied. Instead it has just been encouraged," Coker
said. "The reclassification is being read [by potential users] as a signal
that there is a more relaxed attitude to all drugs, and that is very
dangerous." Bob Carstairs, of the Secondary Heads Association, is also
concerned about the message sent to children by the reclassification.

His organization, which represents head teachers at more than 4,000 schools,
has recommended that they maintain a policy of suspending first offenders
and of expelling those who sell cannabis to their school mates, or who
otherwise encourage consumption of the drug.

"The majority of heads are disappointed at the confused message that is
being sent," Carstairs said last week. "There is a huge amount of confusion.
There are eight-year-olds trying cannabis. They are simply too young to make
a mature judgment." But predictably others criticize the policy for not
going far enough. Francis Wilkinson, a former chief constable of Gwent, says
the cannabis laws discredit all drug laws.

"Children experiment [with cannabis] and find it is not harmful. They then
think that all the laws are wrong, even those dealing with drugs that are
very damaging." He says cannabis and heroin have a completely different
impact on the individual and on society.

"For example, people who smoke cannabis do not commit crime to get more,"
said Wilkinson, who claims widespread support within the police force. "If
there is one thing that would substantially reduce crime, it is government
regulation and control of the supply of both cannabis and heroin," he said.
Another supporter of the reform is Mike Trace, the Government's former
deputy drug tsar from 1997 to last year. He said that, in 1999 and 2000, he
and his staff calculated that "in the realms of pounds sterling 100 million"
would be saved by the criminal justice system if cannabis was legalized. He
blames fear of a "Middle England" backlash for politicians' failure to push
through radical measures. "There is a fear of being portrayed ... as soft on
drugs," he said. Some, such as Iversen, advocate a "coffee shop system" like
Holland's. "We need to separate the supply of cannabis from those drugs that
are more harmful." However, major change in drugs legislation is unlikely in
the short term, not least because Britain is bound by a series of UN
conventions to keep cannabis use illegal. Policy is likely to come from the
broad moderate consensus represented by drugs professionals such as Power
and others working on the front line of drugs and mental illness in Lambeth.
Despite his concerns on health issues, Power backs reform.

recreational use "The main risk is the extremely detrimental effects on
youngsters of being caught up in the criminal justice system simply because
of the recreational use of a drug that has relatively limited adverse health
effects compared to other drugs and alcohol," he said.

Most health professionals see education as the critical issue. The Home
Office officials say they are sensitive to the need for teaching people
about health risks and are investing pounds sterling 1 million in a campaign
to educate the nation about the new legal situation regarding cannabis use
and about the impact smoking the drug can have on bodies and minds.
Campaigners such as Hammond say that much more effort is needed.

What no one denies is that millions in Britain will continue to use cannabis
- -- whatever the legal situation and whatever the health advice. Alex makes
pounds sterling 50,000 a year selling cannabis and cocaine to mainly
middle-class clients.

"Even if they legalize cannabis, it would be taxed and we could undercut
it," he said. "The really low-quality goods would be taken off the market
and some street dealers would go out of business. But I'd carry on. There is
a huge demand for cannabis. That's capitalism. Where there is demand, there
will always be a market."
