Governments all over
the world have spent decades and billions fighting a "war on drugs".
However, many believe that the most commonly used illegal drug, cannabis,
should not be illegal at all.
Advocates of
legalization point out cannabis' medicinal properties, its ability to open up
the mind, and plentiful evidence that it is less harmful than both alcohol and
tobacco. Critics of legalization meanwhile cite studies showing cannabis'
harmful physical and psychotic effects and its tendency to act as a gateway to
harder and more dangerous drugs.
The debate can also be framed as one that pits the concept of freedom of
the individual against the concept of the paternalistic state. Some will argue
that people should be allowed to do whatever they please to their own bodies.
Others believe the state has a responsibility to protect people from harming
themselves, and indirectly harming others, by smoking cannabis.

People should be allowed to do whatever they want to
their own bodies. It is important
that we have the liberty to do what we want to our own bodies. People are
allowed to eat or drink to their detriment. In many countries it is legal to
take one's life. Why then, should people not be allowed to harm themselves
through cannabis use? (Assuming that cannabis use is harmful. In most cases,
this is highly debatable.)
Smoking cannabis may have effects on others, such as
through the effects of passive smoking. However, regulation has been brought
in to minimize the effects on others for alcohol and cigarettes, such as bans
on smoking in public places, and the same thing could be done for cannabis.
|
While individual
liberty is an important good, there are cases in which a Government can be
justified in behaving in a paternalistic manner, even to prevent individuals
harming themselves. Few people debate the law that you must wear a seatbelt
in cars, for example.
Moreover, cannabis
can harm others and many of the ways in which it does so would not be
possible to counter with regulation. In the words of philosopher George Sher,
"Drug use harms strangers by involving them in the collisions, shootouts
and other catastrophes to which the impaired and overly aggressive drug users
are prone. It harms family members by depriving them of the companionship and
income of their addicted partners. It harms fetuses by exposing them to a
toxic and permanently damaging prenatural environment. It harms children by
subjecting them to the abuse of their drug-addled parents".

Alcohol and tobacco are more harmful drugs, yet remain
legal. Although cannabis can have some harmful effects, it is
not nearly as harmful as tobacco or alcohol. Research by the British Medical
Association shows that nicotine is more addictive. In England and Wales,
cannabis was said to have helped cause 17 deaths, compared to 6627 for
alcohol and 86,500 for tobacco. A study, published by The Lancet, that scores
drugs out of 100 for the harm they cause the user and others, gave alcohol
72, tobacco 27 and cannabis 20.
Given that tobacco and alcohol are more likely to harm
the user and other people, it seems ludicrous that they should be legal and
cannabis should not be. The legalization of cannabis would remove an anomaly
from the law.
|
It is difficult to assess the true harm caused by
cannabis. There are limits to the scope for information on its effects
because of its illegal nature. However, it is widely acknowledged that there
are links between cannabis use and mental and physical health problems. It is
also widely acknowledged that excessive cannabis use can harm relationships
and prevent people from acting as functional members of society. Cannabis is
generally smoked with tobacco and cannabis users are more likely to drink
alcohol. Regardless of whether cannabis itself is worse for you than tobacco
or alcohol, it is still bad for you and therefore it should remain illegal.
The reason alcohol and tobacco are legal is not related
to their effect on our health. They (alcohol and tobacco) are legal as they
have existed in this country since long before laws were passed in relation
to health and were far more popular than cannabis so it would have been much
harder to ban them. Cannabis is illegal not because it supposedley is worse
but because it is was less commonly consumed. That said, alcohol and tobacco
are irerelvent in this debate.

If cannabis was legalized, it could be regulated. Many of the problems associated with cannabis use
arise from the fact that it is illegal. Cannabis is the world’s most widely
used illegal drug – 23% of Canadians admit to having smoked it and up to 7
million people in the UK are estimated to do so.
In 2009, the UN estimated that the market for illegal
drugs was worth $320 billion. This market is run by criminals and is often
blighted by violence. It has cost thousands of innocent lives, particularly
in supplier countries such as Mexico and Afghanistan. In the US, Milton
Friedman estimated that 10,000 people die every year as a result of drug
dealers fighting over territory. Many of the victims are innocent people,
caught in crossfire. By legalizing cannabis, the size of this market for
illegal drugs would be significantly reduced and so, effectively, would the
number of crimes and unnecessary deaths that come with it.
Another way of seeing the problems of prohibition is to
look at the failed attempt at alcohol prohibition in the 1920s. People
continued to consume alcohol, only it became 150 per cent stronger, was as
easy to obtain for minors as for adults, and was sold by murderous gangsters
like Al Capone.
Given all of the problems associated with prohibiting
cannabis, it seems nonsensical to spend billions fighting a drugs war when
instead governments could reduce crime and make money by selling cannabis in
a regulated manner. They could spend some of the profit on treating people
who did experience any harmful effects.
|
Legalizing cannabis would not stop the criminals who
currently sell it from continuing to commit crimes. They could simply
diversify their activities. Many of them would already be dealing other drugs
or involved in other criminal activities. The legalization of cannabis could
simply give them a legitimate base from which they may operate.
In order to end the "war on drugs" and the
problems of violence associated with it, all drugs would have to be
legalized. While some debate the harmful effects which cannabis may have, few
argue that drugs like heroin and crack cocaine do not present a serious
threat to people. To sell these kinds of drugs legally would be irresponsible
and would ruin lives, families and communities.

Cannabis opens the mind in a positive and beneficial
manner. Cannabis use can alter one's perception of reality or
consciousness. The alteration need not be thought of as spiritual or religious
to be respected for what it is; a fresh look on a reality that we are
programmed as humans to perceive only in a particular manner. Cannabis can
help humans perceive that complex reality from simply a different
perspective, which can benefit our appreciation for that reality and our
unique and limited perceptions of it. With this more intelligent approach to
cannabis consumption, it is easy to argue that mental, perceptual, and
societal benefits exist.
|
Cannabis does not open the mind. Rather, it harms it.
Many researchers have concluded that cannabis impairs short-term memory,
cognition and motivation. It has also proven to be highly addictive for some
users and has damaged people's mental capabilities and abilities to function
in society.
|
There is little evidence of cannabis being a gateway
drug. In fact, there is a higher correlation between cigarette smoking and
hard drugs. If anything, the only way in which cannabis could be said to be a
gateway drug is that it is illegal and people may be inclined to buy other
illegal drugs after they have bought cannabis, particularly as some dealers
will sell other drugs. This problem, however, would be immediately eradicated
if cannabis were legalized.
|
Cannabis is a gateway drug. People who use cannabis will be more likely to move on
to harder drugs. While the bad effects of cannabis may be disputed, the
harmful effects of hard drugs cannot – they seriously damage people’s health.
A major study in 2011 found that ‘smoking cannabis daily sets users up for a
lifetime of multiple drug use’. Heavy users are more likely to resort to
crime to fund their addiction. Their habit often harms their relationships
with friends, colleagues and family. State money then has to be spent on
benefits, on policing, and on rehabilitation programs.
|
Legalization of cannabis would make it easier for
scientific studies to take place, thereby providing a more accurate picture
of the physical, psychological, spiritual and sociological effects of the
drug. Just as the lift of the taboo on discussions of a sexual nature in
schools around the world has resulted in people being more informed as to the
dangers of unprotected sex, so would the increased availability and accuracy
of scientific data on cannabis serve to reduce the ratio of abuse to responsible
use.
|
Uncertainty over the effects of cannabis means it is
best to be prudent. The debate over the
effects of cannabis is based largely upon conflicting evidence. For example,
some argue it can cause psychosis while others argue it only has positive
effects on the mind. The effect of any illegal drug is a very difficult area
to study. Most drug users use more than one drug and researchers are often
limited to studying those who admit themselves into clinics with a crisis –
something of a skewed sample.
Given that Governments cannot accurately predict what
the effects of legalizing cannabis would be, it is prudent to maintain
illegality. What if, for example, a state decided to legalize cannabis, to
only discover five years later that it has a dramatically more negative
impact on human cognition than previously thought, or that it substantially
increased the risks of psychosis?
|
Firstly, it is not necessarily a bad thing for cannabis
use to increase. Countries with the highest usage rates include some of the
most prosperous in the world – Canada, Australia and New Zealand for example.
Even if increased cannabis use is a bad thing, there is
little evidence to prove usage would necessarily go up if cannabis were
legalized. Usage may have risen slightly in the Netherlands but cannabis was
depenalized in 1976 and usage rates remain lower than in the US today.
Moreover, there are other reasons why usage rose. According to Dirk Korf of
the Institute of Criminology at the University of Amsterdam, "There is
no appreciable causal connection between the Dutch decriminalization of
cannabis and the rate at which cannabis use has evolved".Portugal
decriminalized drug use in 2001 and, a decade later, drug usage and drug
related crime rates have fallen and cannabis use remains below the European
average.
|
More people will use cannabis if legalized. If cannabis is legalized, it will become socially
acceptable and more people will smoke it. It will also become more readily
available. In the Netherlands, cannabis usage went up after it was
legalized1. With more people smoking, more people will experience the adverse
physical and mental health effects - more people will be harmed. Furthermore,
as Dr. David Murray has noted, 'marijuana use is the leading cause of
treatment need for those abusing or dependent on illegal drugs'; therefore
not only will more people use cannabis, more of them will be addicted.
|
While there are studies that argue that cannabis is
harmful, there is no substantial proof of many of the harmful effects it is
accused of having. Indeed, there are many studies that claim it does not have
these harmful effects. For example, a 15-year John Hopkins University study
published in May 1999 found "no significant differences in cognitive
decline between heavy users, light users, and non-users of cannabis." It
is also claimed by many researchers that while cannabis has some potentially
harmful effects, it is far less harmful then tobacco and alcohol. Cannabis is
also known to have medicinal qualities, such as in relieving pain for MS
sufferers. In California, for example, it is possible to obtain a
"medical marijuana" card.

Cannabis is harmful. Studies have shown
that cannabis may cause a number of physical and mental problems. It can
cause respiratory problems, increase one's heart rate and lower one's sperm
count. Cannabis use is also associated with causing or worsening some forms
of psychosis. It has also been found to increase tiredness, depression and
paranoia, impair short-term memory and hormone production and cause general
cognitive decline. As for cannabis' medicinal qualities, safer, more
effective drugs are available. They include a synthetic version of THC,
cannabis' primary active ingredient, which is marketed in the United States
under the name Marinol.
