The population of the UK spent £6.7 billion on illegal drugs in 2013 according to the Office of National Statistics.
Drugs are a fact of modern life.
Drugs are present everywhere including school, and yes, that includes the school that your child attends.
Bear in mind that according to the NHS, 1 out of every 10 eleven-year-olds and 1 out of every 4 fifteen-year-olds have tried drugs.
These figures do not come from some scaremongering newspaper looking to shock readers to increase sales, or some sanctimonious person moralising about the 'youth of today'. These are figures collected by the National Health Service of England and Wales.
So unless your eleven-year-old child meets with less than 10 children each day at school, they will know someone who has tried drugs. Furthermore, given how freely children talk among themselves, it is very likely that they will know of this child's experience which will usually be described in glowingly positive terms.
Unfortunately, while pupils will find drugs readily available at school, they will not find accurate and balanced information equally on offer.
If the child who has experimented is one of your children's friends or a friend of a friend of theirs, they may be persuaded or tempted to try drugs themselves. Even if it is not one of their friends, the peer pressure or temptation can be very strong based on the information that they receive and their desire to be accepted.
This does not mean you are a bad parent nor does it mean you have a bad relationship with your child.
Sadly, there are many stories of children raised in loving homes by good parents that have taken drugs. If you are in any doubt, a brief search of the news media will reveal many such tragic stories. Do not be complacent.
Drugs are a highly complicated and charged subject. Many children who communicate well with their parents on difficult topics like sex, will hold back when it comes to drugs for fear of judgement and reprimand.
So what can you do, other than despair?
Lock your children up and cut them off from society, or threaten them with a string of severe punishments that will bring their social lives to a sharp end?
It will not work. It will only encourage your children to deceive you if they ever try drugs.
You need to know as much as you can about drugs. Read, read, and read.
Deal with the issue head on. Raise the topic with your children. Do not wait for them to talk to you about drugs. Do not hesitate. Do not be scared.
Start talking as soon as you can about taking drugs, and keep talking until they reach adulthood. You need to make sure that there is no hesitation to talk about the subject.
Any moral judgements and condemnation will not prevent children from taking drugs. What they will do, is dramatically reduce the chances of them talking to you about the subject.
It is very tempting to go on about the 'evils of drug use' and remind your children that all you want is for them to be safe, but resist the temptation because it simply does not work. Do not underestimate the power of peer pressure and curiosity.
Their peers will tell them how good drugs feel. They will talk about the pleasure of being high.
Do not pretend that there is no positive side to drug taking. Do not let them hear it only from their peers. Present a balance argument.
Talk about the pleasure of being high, and the risk of becoming addicted. Talk about feeling calm and relaxed, versus the anxiety of coming down. Talk about being able to forget all your troubles while on drugs, and the loss of time, memory and health that results.
Help your children to make wise, informed decisions. If they decide that the risks are not worth the pleasure, there is a far greater chance they will refuse drugs when the opportunity arises, and the opportunity will arise when you are not around. That much you can be certain about.
Encourage them to ask questions and to challenge what you tell them. Do not be worried about not knowing the answer, but instead use questions you cannot answer as a chance to do research together.
A good place to begin is to learn about the most commonly tried and used illegal drugs in the UK.
Never feel scared to ask professionals. Start by speaking to your GP. They will be able to offer advice without judging, and more importantly, connect you with the appropriate services and specialists to help.
The President of Colombia, Juan Manuel Santos, has used his Nobel Peace Prize acceptance speech to call for the world to "rethink" the war on drugs.
He said the zero-tolerance policy might be "even more harmful" than all the other wars being fought worldwide.Drugs workers fear a "bad batch of heroin" could have led to the deaths of at least seven drug users in recent weeks in the Gwent Police force area.

Deaths related to drug misuse (England and Wales)
Reports in Tuesday's Guardian were little short of sensational. German research suggests that small doses of tetrahydrocannabinol (THC) produced "profound, long-lasting improvement in cognitive performance".
The results indicated that this could possibly stave off dementia for five to 10 years, the reverse of the impact cannabis is known to have on younger brains. Or at least this was the case with mice. As yet, no one knows about humans.
Two very different stories of the social media war on drugs begin the week: one about Spice in Manchester, one about heroin in Lake County, Florida.
This weekend in Florida, Sheriff Peyton Grinnell posted a YouTube video to scare local heroin dealers. Flanked by a group of balaclava and flak jacket clad heavies, Grinnell stands behind a podium delivering a warning to sleep with one eye open to those people behind numerous local overdoses.
Heroin use among American adults has increased almost fivefold in the last decade, according to a study based on a survey of almost 80,000 people.
Researchers found that just after the turn of the millennium, 0.33% of the adult population reported having used heroin at some point in their life, but 10 years later it had risen to 1.6% - a figure corresponding to about 3.8m Americans.
On 11 September, 2001, hours before terrorists hijacked four planes and ploughed them into New York's twin towers and the Pentagon, murdering almost 3,000 people, Lord Carlile of Berriew accepted an appointment as Britain's independent reviewer of terrorism legislation. From then on, stories of danger, threats and tragedy dominated his professional life during a decade in the role, as attacks spread and counter-terrorism efforts proliferated.
Researchers are planning to investigate whether a drop in drug use among teenagers could be explained by smartphones stimulating effect on the brain.
Levels of smoking, drinking and drug use among British schoolchildren aged 11 to 15 have more than halved over the last decade, according to NHS statistics.

The police force is set to become the first in England to implement an approach pioneered in Switzerland and credited with achieving positive results in a number of European countries but unlikely to attract much domestic political support.
Drugs were seized almost 30 times a day in prisons in England and Wales last year with the weight of the illegal substances confiscated reaching 225kg. The figures come from new government analysis.
Drugs were found on 10,474 occasions last year, with hauls of more than 1kg on 26 occasions, according to new Home Office data, which was introduced in October 2015, meaning there are no year-on-year comparisons.
The government's blanket ban on legal highs, has succeeded in shutting down high street trade in the substances but has led to products such as Spice being sold by street dealers, according to a report.
The survey of the street drug market in Britain by DrugWise, also says unprecedented purity levels in heroin, cocaine, crack and ecstasy, driven by competition, is fuelling a recent rise in drug-related deaths.
"You are corrupt to the core," the Philippines' president, Rodrigo Duterte, said to his police force after announcing he would be indefinitely halting his war on drugs to tackle corruption within the Philippine national police.
This is following the death of businessman, Jee Ick-joo, who was left strangled in the grounds of Camp Crame, the police force's headquarters, after a bungled kidnap and interrogation attempt by anti-drugs officers.
Even the most adamant supporters of the war on drugs agree that it is failing. At a major UN summit on drug policy earlier this year, many member states argued forcefully for a more balanced and humane approach. But there's one anti-drug crusader who refuses to face the facts. For the past six months Rodrigo Duterte, president of the Philippines has waged one of the world's most vicious counter-narcotics campaigns.
A leading drugs reform campaigner has hailed 2016 as a ground-breaking year for research into how psychedelic drugs can help treat illnesses.
"It's been a great year for psychedelic research," Amanda Feilding told The Independent. While most medicines must be taken regularly and repeatedly to be effective "psychedelics seem unique in their ability to produce enduring results after just one or two treatments," she explained.
In 2010, doctors diagnosed Dinah Bazer with ovarian cancer. After treatment and chemotherapy, it went into remission, but she became increasingly terrified that the disease might return. Two years after diagnosis, she felt worse than ever.
She heard about a study at New York University, using psilocybin to treat cancer patients struggling with extreme anxiety and depression.
Natasha Butler had never heard of fentanyl until it pushed her son to the brink of death. "The doctor said fentanyl is 100 times more potent than morphine and 50 times more than heroin," she said as the tears came.
"Jerome was on a respirator. The doctor told me all his organs had shut down. His brain was swelling, putting pressure on to the spine. They said if he makes it he'll be a vegetable."
On 10 December 2006, the newly inaugurated president, Felipe Calderón, launched Mexico's war on drugs by sending 6,500 troops into his home state of Michoacán, where rival cartels were engaged in tit-for-tat massacres as they battled over lucrative territory. The surge in violence had started in 2005, and a string of police and military operations by his predecessor Vicente Fox had failed to stem the bloodshed.
Former inmates are deliberately getting sent back to prison to cash in on lucrative profits on offer for selling drugs previously known as "legal highs", according to a new report.
Prices for the substances can jump 33-fold once they cross into jails - providing prisoners with an incentive to go back behind bars to make money, researchers claimed.
Afghanistan's opium production has risen by an estimated 43% this year.
The annual increase on 2015 levels was due in part to growth of 10% in the area under cultivation, the UN said, from 183,000 to 201,000 hectares.
The UNODC said estimated opium production in 2016 was 4,800 tons, underscoring a worrying reversal in efforts with illegal drugs.
The UK's two leading public health bodies are making an unprecedented call for the personal possession and use of drugs to be decriminalised.
The war on drugs has done more harm than good, say the Royal Society. They argue that drug misuse should be a health issue, not a matter for courts and prisons. More people than ever before are being harmed by drugs and then harmed again by the punishment.
This is a flawed question that illustrates a major paradox in the UK and international laws on drugs. Some drugs such as alcohol, are legal, whereas others such as cannabis, are not. This has not always been the case.
In the 19th century extracts of now-illegal drugs were sold in pharmacies and corner shops. Queen Victoria's physician was a great proponent of tincture of cannabis and is reputed to have used it for menstrual pains and childbirth.
