Go ahead, ask a cop for dope. The Dutch don't mind

It is a weird experience. You walk up to a Dutch policeman, and ask where
to get some marijuana. You are smilingly directed to the nearest "coffee
shop", where the menu offers everything cannabinoid from something called
Space Cake to Northern Lights, a local weed.

In much of the world, this could never happen: the penalties for using
cannabis are severe. But in 1976, the Dutch legalised the possession of
small amounts. What has happened since? Some say that crime has soared,
schoolchildren drop out, and heroin addiction is rife. Others insist the
Netherlands is a stoned paradise of peace and love.

"I've visited their parks. Their children walk around like zombies," says
Lee Brown, head of the US Office for National Drug Control Policy. "Hard
drug use -- heroin and cocaine -- has declined substantially," says Paul
Hager of the Indiana Civil Liberties Union.

Most comments seems to seem to depend on the speaker's politics. So what is
the truth about the great Dutch cannabis experiment?

Hard addicts

"There was no immediate increase in cannabis use after 1976," says Arjan
Sas of the Centre for Drug Research at the University of Amsterdam. "Trends
in use have generally been the same as in other countries." The percentage
who regularly use either cannabis or hard drugs is lower in the Netherlands
than in many European countries, including Britain. And the number of hard
drug addicts in the Netherlands has not increased for a decade, while their
average age is rising.

Dutch statistics, however, are far from conclusive. The first national
survey of drug use in the Netherlands is only just being done. There have
been smaller-scale studies of particular towns or age groups but comparing
them is fraught with statistical problems.

Nonetheless, Dirk Korf of the Institute of Criminology at the University of
Amsterdam has used the smaller studies to estimate that 3 per cent of Dutch
people had used cannabis at least once in 1970, rising to 12 per cent in
1991. The best guess for 1998 is 14 per cent.

Most of that increase, says Korf, is because "lifetime use" figures are
cumulative: people who had used it in 1970 are still around, and are joined
by younger users over time. More to the point, he says, is to compare the
number of teenagers who start using cannabis. In 1970, he estimates that 20
per cent of all Dutch 18-year-olds surveyed had used it at least once; in
1980, that had fallen to 15 per cent. By 1987, it was 18 per cent, an
increase, Korf says, that mirrors the increase in the number of coffee
shops in the mid-1980s. Now, about 30 per cent of Dutch 18-year-olds are
said to have tried cannabis, though some researchers think that is an
overestimate based on studies of Amsterdam where coffee shops abound.

But did more people try cannabis after it was legalised? It seems so. At
the Centre for Drug Research, Sas and Peter Cohen divided Amsterdamers
surveyed in 1987, 1990 and 1994 into two groups -- those that were born
before 1958, who were 18 or older in 1976, and those that were born after
1976, for whom cannabis has always been legal. Only 19 per cent of the
oldies had tried cannabis, compared with 38 per cent of the younger group.

That difference could be partly misleading. Dutch surveys show that the
vast majority of people who use cannabis do so almost exclusively in their
20s. The drug became common in the Netherlands in the mid-1960s, so for the
older group members who were already more than 30, it was too late.
Nonetheless, the data suggest that more people did try cannabis after
decriminalisation.

But what counts, though, says Sas, is how many continue to use it. In
Amsterdam, 55 per cent of people who say they have tried cannabis only end
up using it a couple of dozen times or less. The rest may have used it more
often, but more than half have not used it in the past month. The data
show, says Sas, that legalising cannabis may make you more likely to try
it, but it does not make it more likely that you will continue to use it.

But it is by no means certain that the first half of that conclusion is
correct. Korf finds that surveys of the number of Germans who use cannabis
"virtually parallels" the peaks and troughs in Dutch surveys between 1970
and 1990, even though Germany has prohibited cannabis throughout the
period. Surveys of young Americans in the 1970s and 1980s found
"substantially higher prevalence rates" than in Holland, peaking at 50 per
cent of high-school seniors in 1980, although the US was strongly
prohibitionist.

Legal immunity

Since then, says Korf, there have been no discernible differences in use
between US states that have decriminalised, and those that have not, while
cannabis use has increased in the US and Western Europe since 1990,
regardless of the legal framework. "There is no appreciable causal
connection between the Dutch decriminalisation of cannabis and the rate at
which cannabis use has evolved," Korf concludes.

Last year, Robert MacCoun of the University of California at Berkeley and
Peter Reuter of the University of Maryland, compared trends in cannabis use
in the US, Norway (which bans it) and the Netherlands. They also concluded
that "reductions in criminal penalties have little effect on drug use, at
least for marijuana".

While the 1976 legislation may have had little effect on cannabis use, how
effective has it been in its main goal of keeping people off harder drugs?
The Netherlands has fewer addicts per capita than Italy, Spain,
Switzerland, France or Britain, and far fewer than the US. Frits Knaak of
the Trimbos Institute in Utrecht, the Dutch national institute for mental
health and addiction, says the number of hard drug addicts in the country
has been the same for a decade because fewer young people are joining their
ranks. The average Dutch junkie is now 44 years old and only 0.3 per cent
of Dutch teenagers had tried cocaine in 1994, compared with 1.7 per cent in
the US. In the Netherlands, virtually everyone who uses drugs tries
cannabis first, and many seem content to go no further.

Cannabis addiction and other problems are uncommon. "The number of cannabis
users treated in drugs outpatient facilities is low," says Knaak. "In 1996,
there were only 2000 [patients] in the whole country -- just 0.3 per cent
of all Dutch cannabis users."

Of those, 42 per cent "are also having trouble with alcohol or other drugs
- -- the rest usually just need counselling to help change their lifestyle",
says Sas. Most people who find cannabis causing trouble with concentration
or memory at work or school, he says, apply rules, like no smoking on week
nights, or they limit their intake.

This self-policing seems to work. Dutch teenagers get among the highest
scores in the world on international science and mathematics tests. If
there are serious problems caused by legalising marijuana, then twenty-plus
years of the Dutch experiment has not revealed what they are.
