Should cannabis be legalised?

Should cannabis be legalised?

For the past year cannabis (marijuana, blow, dope) has frequently been in the news headlines in the UK, and it was recently announced that the legal status of the drug is to be reviewed. This may come as welcome news to the many people who use the drug either for medicinal or recreational reasons.

Cannabis can be smoked, usually with tobacco, eaten, drunk in a 'tea' or snorted as a snuff.

Cannabis contains more than 400 chemicals, including 'cannabidiolic acid' - an antibiotic with similar properties to penicillin. However, the main psychoactive ingredient is delta-9-tetrahydrocannabinol, better known as THC.

To simplify a very long and complicated story, THC mimics the actions of receptors in the brain called 'neurotransmitters' and interferes with normal functions.

The cannabis smoke is inhaled into the lungs, where the THC is filtered into the bloodstream. Chemicals called cannabinoids block certain electrical signals inside the brain, interfering with the short term memory and co-ordination.

Sounds may become distorted or hearing heightened. Pressure inside the eye decreases, causing the eyes to redden and the eyelids to become puffy. The air passage to the lungs expands and the mouth stops producing saliva, leaving a dry mouth. Cannabis increases the cardiovascular action of the heart. Blood pressure is altered and the pulse rate quickens. The User also experiences an increase in appetite. Molecules called endo-cannabinoids bind with certain receptors in the brain, making the user feel hungry. Although cannabis isn't an aphrodisiac, many users report heightened sensitivity and increased sex drive.

The effects of cannabis generally last for up to four hours depending on the amount used, and the body resumes normal service after that. There is no 'hangover' as with alcohol, instead users describe the feeling as being 'woolly-headed'.

Origin of the species

The drug itself is derived from Cannabis sativa or Cannabis indica, a plant related to nettles and hops that grow wild in many parts of the world. Cultivation dates back thousands of years. The first written account of cannabis use can be found in Chinese records dating from 2800 BC. However, experts widely accept that cannabis was being used for medical, recreational and religious purposes for thousands of years before that.

The plant is believed to have originated in the mountainous regions of India.

When left growing wild, it can reach a height of 5 metres and flowers naturally from late summer to mid autumn.

Customs estimate that up to 80% of cannabis resin entering the UK originates from Morocco and most smuggled supplies in its herbal form come from Jamaica. However, an enormous amount of cannabis these days is actually home-grown.

Legal status

The supply and possession of cannabis is illegal in the UK and is likely to remain so for the foreseeable future. Even though the Home Secretary, David Blunkett, recently announced that cannabis will be down-graded from a 'Class B' drug to a 'Class C' drug, supplying the drug still carries the risk of a prison sentence of up to seven years, whilst possession for any reason could result in a two year sentence. Similarly, growing cannabis at home for your own use could also lead to a prison sentence. In practice, the police may issue a caution to people caught in possession of the drug, and with the downgrading of the drug to Class C, it is possible that only persistent offenders are likely to find themselves in court.

Medicinal use

Medicinal use of cannabis is illegal and therefore there is little verifiable evidence of the drug's effects when used in the management of chronic health conditions. However, cannabis is widely used by people for medicinal reasons, often for the relief of pain, or as an appetite stimulant. In 1996, a clinical trial in San Francisco found that people with HIV wasting disease who used cannabis were more likely to put on weight. The drug is also widely used to relieve insomnia and the symptoms of anxiety and stress. It is also used by people with multiple sclerosis as a muscle relaxant.

In recent years a small number of people have been prosecuted for growing and consuming cannabis for medicinal purposes. In most cases a suspended sentence has been issued, but recently a jury returned a not guilty verdict, and in another example a judge threw out the case.

The UK Government is currently reviewing the evidence on cannabis use. Cannabis extracts, called cannabinoids, are already legally used in licensed pharmaceuticals, mostly pain killers and muscle relaxants, but these can only be obtained on prescription. These products do not make users feel 'high' or have any of the other narcotic effects of cannabis.

Risks of cannabis use

Short-term risks of cannabis use include anxiety, panic, and paranoia. Memory and attention may also be affected, as might the ability to drive or operate machinery. Research suggests that cannabis use in teenagers is a predictor of later mental health problems. Use during pregnancy has been associated with low birth-weight babies.

If the drug is smoked, long-term use is known to cause many smoking-related respiratory and cardiovascular diseases such as asthma, bronchitis, emphysema

and heart disease. This may be of particular concern to people with HIV who have suffered lung damage from TB, or to those with increased lipids from anti-HIV medication, as this may increase the risk of heart attack. There is also evidence that smoking cannabis can cause cancers of the mouth, throat and lungs.

Chronic loss of memory and shortened attention span have been observed in long-term users of the drug, in some cases even after they have ceased, and there is evidence that long-term users can develop psychological dependency on the drug. In a recent survey, daily use of cannabis by teenagers was found to substantially increase the risk of developing depression later in life and the use of cannabis has also been linked with an increased risk of schizophrenia.

In my investigation I am trying to find out what the public and the government think, what their opinions are and ultimately whether they think cannabis should be legalised and whether they think the laws will be changed.

There are many people who would like to see the drug legalised or decriminalised in this country, but it is important to understand what either of these two actions could result in. If the drug were to be fully legalised, then it would be placed in the same category as alcohol or cigarettes. There would still be laws regulating sales and use but there would no longer be a penalty for the use and supply of cannabis. If the drug were not fully legalised but instead decriminalised, then the laws monitoring the use and sales would be different but still in place. For example, if it were decriminalised then it would be legal to possess small quantities of the drug, in any form, for personal consumption. It would still be illegal to produce or supply the drug however. Eventually, the argument still boils down to one factor, whether or not the public chooses to use the drug or not.

There are many reasons arguing for and against the legalisation issue and I have tried to list the most important factors leading to a decision here.

For the legalisation of cannabis:

* There are at least 21/2 million (perhaps 7 million) cannabis users in the UK.

* Otherwise innocent people convicted of drug offences have their future prospects massively hampered.

* Cannabis is often contaminated with inert or toxic components which cause more harm than the cannabis. A legal supply would be pure and therefore safer.

* Legalising does not mean glamorising ...
