Summary

Magnesium is a vital element for humans, plants and animals. Among other things it is a building block for chlorophyll in plants so it is essential for photosynthesis and it also plays an important role in a number of metabolic processes. Magnesium compounds have been used since antiquity in medicine for heartburn, against poisoning and as a laxative. Magnesium powder is used on equipment for gymnastic exercises because it makes the hands rough and absorbs moisture. Magnesium is a very light, malleable, elastic metal with a silver-white sheen that burns with a blinding light in the air. It is one of the most common elements on earth and the earth’s crust contains approx. 2.09% magnesium, but only in compound form. Magnesium compounds are frequently found in seawater, salt deposits, water from salt lakes and in some mineral waters. It is also present in tap water and, together with calcium, is responsible for the hardness of water. Inorganic, magnesium fertilizers are prepared from the same salts as are used when preparing potassium fertilizers. When grown from seeds cannabis don’t need extra nutrients for the first two weeks.

• There are no visible symptoms in the first 3 – 4 weeks, the plant continues to grow well, is dark green and looks healthy.

• The deficiency symptoms first become visible in cannabis after 4 – 6 weeks when small, rust brown necrotic spots and/or cloud-like chlorosis appear under the flowering top on the middle-aged leaves. The color of the young leaves and the development of the flowers remains normal.

• The size and number of the rust brown spots increases on the leaves while the chlorosis also spreads and becomes yellower.

• The symptoms spread throughout the plant which will now look a sorry sight.

• If it is a serious deficiency the young leaves will also become chlorotic and production will fall.

Developments in chronological order:

Symptoms

Magnesium is mobile in the marijuana plant so if there is a deficiency, the chloroplasts in the middle-aged leaves that are below the flowering top are broken down and the magnesium is transported to the young parts. This process of breaking down the chlorophyll is manifested in the rust brown spots and/or vague, cloud-like chlorotic spots between the veins. It is more difficult to extract magnesium from the older leaves because the magnesium is an intrinsic part of the organic material. A minor magnesium deficiency has little effect on flowering despite the fact that the formation of flowers makes the magnesium deficiency symptoms worse.

• The deficiency symptoms first become visible in cannabis after 4 – 6 weeks when small, rust brown necrotic spots and/or cloud-like chlorosis appear under the flowering top on the middle-aged leaves. The colour of the young leaves and the development of the flowers is still normal.

• The size and number of the rust brown spots increases on the leaves while the chlorosis also increases and becomes yellower.

• The symptoms spread throughout the plant which will now look a sorry sight.

• If it is a serious deficiency the young leaves will also become chlorotic and production will fall.

Possible causes

Magnesium deficiencies in cannabis occur more often relative to other deficiencies. Magnesium deficiency in the root environment can also occur when magnesium levels are normal or high as well as when there is a deficiency. This is because absorption can be slowed down by all sorts of circumstances.

Some of these are:

• A very wet, cold and/or acidic root environment.

• High levels of potassium, ammonium and/or calcium (for example a lot of lime in the tap water or lime rich, clay ground) compared with the magnesium levels.

• Limited root system and a heavy load on the plants.

• High EC in the medium, inhibited evaporation.

What should you do?

• Use fertilizers that contain magnesium as a preventative measure and spray with Epsom salts as a curative measure.

• Check the temperature, humidity, EC and pH in the soil or substrate.

• Go to the shop for expert advice. They specialize in this crop and have the right products available. Correctly formulated fertilizer contains sufficient magnesium.

• If it has been established that there is a deficiency you should spray with a 2% solution of Epsom salts.

Fertilizing via the roots: Inorganic: Epsom salts on hydro, kieserite on soil. Organic: old, rotten stable or turkey manure.

• Correct possible causes: If the pH is too low (< 5) when cultivating in soil use turkey manure which contains magnesium. With hydro cultivation temporarily drip feed the nutrient solution at a higher pH of 6.5. If the EC is too high rinse and/or drip feed with just tap water temporarily. When cultivating inside keep the root temperature above 19 ?C (20-25 ?C).

A little extra magnesium won’t do any harm and excess magnesium doesn’t occur very often when cultivating with soil. If there is too much magnesium, calcium absorption will slow down and it will look like there is too much salt because growth will slow down and the crop will turn dark green.

Over the past 6 months the UK’s Advisory Council on the Misuse of Drugs (ACMD)—an independent expert body that advises government on drug-related issues—has hardly been out of the headlines. One sacking and seven resignations is not a good track record for any organisation. The public’s discontent at the ACMD over how it operates and how it is unduly influenced by government has left a bitter taste, together with a crisis in confidence about evidence-based policy making in the UK.

The trouble at the ACMD began in October, 2009, after the controversial sacking of the then chairman, Professor David Nutt for criticising the government’s policy over cannabis and ecstasy. Five more members quit soon after in protest. In January, 2010, the equally distinguished neuroscientist, Professor Les Iverson, was appointed interim chair. In March, 2010, Dr Polly Taylor was the next to leave, outraged by the publication of the revised Code of Practice for Scientific Advisory Committees, the rewording of which compromised scientists’ independence and would dissuade them from giving objective advice lest they disagreed with government policy.

The current outcry at the ACMD is over the recreational drug mephedrone (4-methylmethcathinone), a synthetic stimulant most similar chemically to amphetamines. It is a derivative of cathinone, a compound found in the plant called khat. Clinical and pharmacological research on cathinones is sparse and knowledge about the human effects of this drug class have been reliant on anecdotal reports from users and physicians. Adverse reactions include tachycardia, hallucinations, vasoconstriction, increased anxiety, and possible psychosis. The substance has received substantial media attention in the UK after reportedly being linked to 25 deaths. Indeed, the ACMD has suggested that media coverage has increased the use of the drug.

The most recent resignation was Mr Eric Carlin in response to the reclassification of mephedrone to class B together with its subsequent ban alongside other cathinone derivatives. According to Carlin, the decision-making process focused primarily on the chemistry and legality of the drugs, and too little on the public health measures that could reduce harm. Furthermore, the ACMD report, Consideration of the cathinones, which recommended the ban, documented the very scanty evidence on mephedrone, including the absence of a direct causal link between the reported deaths and the drug. Alarmingly, the report, which was only a draft, was still being discussed by the ACMD when Iverson rushed out of the meeting to brief Home Secretary Alan Johnson of their recommendation in time for a press briefing. Carlin states on his blog: “We were unduly pressured by media and politicians to make a quick, tough decision to classify.”

Equally notable was the very quiet release on the same day of the ACMD’s other report, Pathways to Problems—a detailed progress report on recommendations made in 2006 on hazardous drug use. The report contains some potentially unpalatable conclusions on tackling young people’s problems, including not enough being done on alcohol and tobacco, as well as calling for a review of the Misuse of Drugs Act 1971. Yet this report received no media attention or a response from the Home Office. Instead, it conveniently got buried under discussions on the legal status of mephedrone.
There was little time to consider carefully the scientific evidence on mephedrone. The ACMD did not have sufficient evidence to judge the harms caused by this drug class. It is too easy and potentially counterproductive to ban each new substance that comes along rather than seek to understand more about young people’s motivations and how we can influence them. We should try to support healthy behaviours rather than simply punish people who breach our society’s norms. Making the drug illegal will also deter crucial research on this drug and other drug-related behaviour, and it will be far more difficult for people with problems to get help.

The terms of engagement between ministers and expert advisers endorsed by Alan Johnson have been blown apart. During the past 12 years the Labour Government has done a great deal to build up a strong science base in the UK and enhance the important role that science plays in our economy and society. However, the events surrounding the ACMD signal a disappointing finale to the government’s relationship with science. Politics has been allowed to contaminate scientific processes and the advice that underpins policy. The outcome of an independent enquiry into the practices of the ACMD, commissioned by the Home Office in October, 2009, is now urgently awaited. Lessons from this debacle need to be learned by a new incoming government.

Richard Friar, a 66-year-old farmer from Australia, and his wife Wendy are the proud owners of Australia&acute;s first licensed industrial hemp crop to be grown in an urban area.

With permission from the Department of Primary Industries, they are in the first stages of a pilot project aimed at teaching farmers how to grow hemp and commercialise its countless byproducts.

The Friars are hemp evangelists, firm believers in the world-changing potential of this most versatile of plants, which can be used in everything from food to fabrics and building materials.

With permission from the Department of Primary Industries, they are in the first stages of a pilot project aimed at teaching farmers how to grow hemp and commercialise its myriad byproducts.

The Friars’ crop, a mix of Chinese cultivars known as Yellow River and Lulu, is a fine example: the stalks can be used in the textile and construction industries – “they even use it, instead of steel, to reinforce concrete” – while the seeds can be eaten.

In December the couple applied to Food Standards for permission to sell the seed for human consumption, with approval expected early next year.

“They are a real superfood,” Wendy says. “It’s 23 per cent protein, and has more Omega 3 and Omega 6 than virtually any other source, including fish.

”In the early 1800s, Australia was twice saved from famine by eating virtually nothing but hemp seed for protein and hemp leaves for roughage.”

But the couple also plan to become brokers for hemp products, importing seeds and matching overseas and local producers with those undertaking retail or construction projects.

“We want to kickstart consumer demand,” Wendy explains. “It’s hard, though, because hemp has for so long been vilified as a dangerous drug.”

A film-maker, farmer, former horse trainer and grade rugby union player, Mr Friar has long been interested in permaculture and recycling; his company King Poo was one of the first to sell worm farms in the early 1990s. But it is hemp that has him raving.

“As a grandfather several times over, I am championing this now as the answer to a lot of our sustainability problems. We just have to lose the baggage we have about hemp, and approach it in a more mature way.”

Another crazy news story from the UK. As you might have read David Nutt was sacked because of him criticizing the Government’s decision to reclassify cannabis as a Class B substance.. He argued that the scientific research was devaluated and the UK government making an “artificial” separation of alcohol and tobacco from illegal drugs.

If you thought that was strange, wait until you hear this.. The new chairman that will replace David Nutt, Les Iversen, had exactly the same opinion with regards to Cannabis. During a lecture in 2003 he said the following;

“There have been no deaths to date caused by use of cannabis. Cannabis should be legalised, not just decriminalized, because it is comparatively less dangerous than legal drugs like alcohol and tobacco.”

In an article in 2003 he wrote that cannabis had been incorrectly classified for nearly 50 years as a dangerous drug and that it was one of the “safer” recreational drugs.

When he was questioned about these remarks during an interview on BBC Radio 5 Professor Iversen stated the following; “I don’t remember saying that. It’s certainly not my position now”

“We have now to confront the more potent forms of cannabis. We have the new evidence that arose since 2003 linking cannabis to psychiatric illness. I think it’s quite free for a scientist to change his mind when faced with new facts.”

We wonder what these new facts are? Is it the fact that he will get sacked, like David Nutt,  if he says that cannabis should be legalized? Or the fact that he would never have been appointed in the first place if he still had that opinion?

The Czech Republic is bringing in some very interesting legislation in 2010.

From January 1st, individuals in possession of 15 grams of cannabis or less will not be charged with a crime in the Czech Republic. The new laws, which decriminalize the possession of ‘small amounts’ of most currently illegal drugs, are based on a  Justice Ministry proposal which was approved by the Czech government earlier this month.

Previously, there were few clear definitions of what level of drug possession was treated as ‘small’, since standards were based on internal police directives and could change from region to region. The new legislation clearly defines how much of each substance is considered a ‘small amount’ under the law. Individuals in possession of this amount or less will not be charged with a crime.

Additionally, the new laws seem to make it possible for individuals to grow up to five cannabis plants. However, if current Dutch legislation is anything to go by, this may not necessarily include indoor growing with lamps, nor allow households with several adults to grow five plants each.
In any case, this new legislation is a big step in the right direction and we hope that other European countries will be inspired by the Czech move towards a sane drug policy.

The Cannabis Cultuurprijs 2009, now in its sixth year, is presented to individuals who have made significant contributions towards the acceptance of cannabis in all its forms and to the reintegration of marihuana and hemp culture into modern society.

At a time when ‘zero tolerance’ is replacing the ‘tolerance policy’ it is more important than ever to acknowledge those who have made a genuine difference to the perception and use of this unfairly maligned plant.

Though other prizes exist in the sphere of cannabis and hemp, only the Cannabis Cultuurprijs celebrates improvements to quality of life and knowledge in quite this way.

The prize itself promotes the achievements of the winner: a unique exhibit dedicated to each one is created for public viewing. Displays honoring previous winners Jack Herer and Ed Rosenthal are on show in the Hash Marihuana & Hemp Museum. Last year’s winner, the late Simon Vinkenoog, is represented in the Hemp Gallery.

A monetary award of ?3000 is also presented. The prize is annually awarded in November. It is independently funded and therefore free from political influence.

Here is a list of some of the negative effects of the ban on cannabis:

1. The ban on cannabis means that in addition to the coffeeshops and people who grow for their own use, an illegal market in cannabis also exists. There is no possibility of control over this illegal market which leads to criminality, unsafe situations, and events that disturb the peace; and to which underage people have easy access.
2. The ban on cannabis makes large scale crops and export of the product into a lucrative source of income for criminal organizations which can then use this income for other criminal activities, or ‘wash’ it via money laundering operations that can disturb the legal economy.
3. The ban on cannabis encourages criminal and antisocial behavior: rules concerning safety and security (for growing and in the marketplace) are easily broken and this goes unpunished. Conflicts are resolved using violence.
4. The ban on cannabis leads to an increase in prices, as the producer in an illegal market calculates their risk into the price.
5. The ban leads to a migration of tourists to coffeeshops near the borders of the country, and the operation of ‘drug runners’ to transport the product. Simple solutions for this problem such as the proposal for a so-called ‘Weed Boulevard’ with legal supply logistics are held back by the ban on cannabis.
6. The ban on cannabis puts enormous pressure on the resources of the police and the justice system, which cannot then devote them to other, more important goals. Some of the methods used to enforce the ban limit the personal freedom of civilians and are a matter of contention in court.
7. The costs of enforcing the ban on cannabis are not justified by the results. Although the goal of the ban (an essential reduction in supply and demand) fails to come a single step closer, the ban itself is never brought forward for discussion.
8. The ban on cannabis damages the credibility of the government, given that the use of cannabis continues to be firmly naturalized in society.
9. The (world-wide) ban on cannabis is one of the pillars of the U.S. dominated War On Drugs, which has led to sizeable global violations of human rights; and severely damages both the environment, and the security of the populations of cannabis-producing lands.
10. The ban on cannabis impedes the development of the industrial applications of the plant, which is capable of making a very valuable contribution to a sustainable future.
11. The ban on cannabis makes it impossible to carry out standardized controls on the product. Therefore demands can hardly be placed on the product in terms of consistent quality, health, or accompanying information on the contents and effects of the product.
12. The ban on cannabis leads to unwelcome and unhealthy practices in production which negatively affect the quality and effects of the product, and thereby damage the health of the consumer.
13. The ban on cannabis criminalizes the cannabis consumer (over one million Dutch people), with negative social consequences for the people in question, their relationships, their family, and their home and work environment.
14. The ban on cannabis is a restriction of the right to freedom of expression. It legitimizes information about the supposed evils of cannabis, information that cannot be seriously tested for durability, credibility or truthfulness and yet is used as justification for the active enforcement of the ban.
15. The ban on cannabis damages the right of the individual to make decisions about his / her own body.
16. The ban on cannabis damages the right of the individual to possess a medicine that is necessary to maintain or support his or her health and wellbeing.
17. The ban on cannabis dissuades doctors from prescribing it to patients who could benefit from the effects; and delays the process of recognition of its medicinal applications in the treatment of multiple afflictions such as HIV and AIDS, Multiple Sclerosis, cancer, and chronic pain.
18. The ban on cannabis denies the government the possibility of levying taxes on the product.
