Amphetamine diet pills are hardly new, according to Professor Hamid Ghodse, former president of the UN's International Narcotics Control Board and chairman of addiction psychiatry at StGeorge's Hospital, London.
"They've been around in various guises since the Sixties and are highly addictive. Users can experience painful withdrawal symptoms, including nausea, headaches and convulsions, when they try to stop taking the drug.
"People take them innocently, thinking it might be an easy way to lose weight, but become hooked.
"The big difference is that now, it seems, instead of having to find an unscrupulous doctor to prescribe the pills, people can simply buy them on the internet."
The drugs work by stimulating the central nervous system, mimicking the natural effect of adrenalin by increasing the heart rate and suppressing the appetite.
"Users also feel euphoric and have increased energy levels," says Prof Ghodse. "However, this also leads to insomnia. Over time, sleep deprivation, coupled with weight loss caused by what basically amounts to starvation, can cause extreme changes in behaviour.
"Users have hallucinations, mood swings, become anxious, paranoid and sometimes violent.
"Because of extreme stress on the heart and raised blood pressure, side-effects can include convulsions, heart attacks, strokes and even death in extreme cases.
"There have been scandals about certain diet pills due to these side-effects.
"The manufacturers have responded by simply removing the drug from the market, changing the formulation slightly and bringing out what is basically the same substance under a different name."
Endocrinologist Dr Nicola Bridges, an authority on the medical treatment of obesity, says anorectic diet drugs rarely help people lose weight in the long term.
"Most people simply put the weight back on once they stop taking the drugs," she says.
"These are extremely dangerous in the wrong hands. They have to be prescribed by a doctor who has carefully assessed the risk versus benefit for the patient."
The National Institute for Clinical Excellence (NICE) recommends that anorectics should be prescribed only to people with a BMI of 27 or over, for short-term use.
Yet despite having a healthy BMI of 22, during this investigation I was able to buy an array of prescription-only appetite suppressants-from internet sources - despite flagging up medical conditions that should have prevented me taking such drugs.
When I typed the word "phentermine" into a search engine, it returned more than 43 million hits.
Even the WeightWatchers community chat website had more than 80 message-board entries in which users talked about using phentermine - also commonly sold online under the brand names Duromine, Ionamine, Adipex and Fastin.
One website, which claimed to be "the official phentermine site", featured photographs of doctors in white coats and promised "no prescription required, no appointments, no waiting rooms and no embarrassment".
I ordered 30 tablets of phentermine for £67. Before giving my credit card number, I was asked to fill out a medical questionnaire.
I put in my low BMI - which should instantly preclude me from taking diet medication - and claimed that I am a smoker with high blood pressure and cholesterol, and have a family history of heart attacks.
Though none of this is true, they are conditions which would make taking a drug such as phentermine, which raises the heart rate, extremely dangerous.
Despite this, my order is processed and within a week a small plastic bottle containing 30 tablets arrives in a packet postmarked Pakistan. The label, which looks as if it has been made using a home computer, simply says "phentermine, 37.5mg".
From a Swedish site, I buy amfepramone, identified by the UN as another highly abused anorectic, and phenylpropanolamine, a diet pill no longer prescribed in Britain or the U.S. because it was found to cause strokes.
Again the site asks for a short medical history and I claim to suffer from chronic heart disease and hypertension. Regardless, after handing over my credit card details, the order is processed.
Three days later, a package arrived containing blister medication packs taped to a piece of A4 paper and a "prescription" from Dr Thomas Wehrle MD, a specialist in "internal medicine" based in Solothurn, Switzerland.
It advised me to read the "approved labelling and manufacturer's package insert for further information, especially on sideeffects and precautions".
Unfortunately, the labelling and instructions are in German.
I also bought the ADHD drug Ritalin, from a source in the Philippines. The tablets arrived ten days later, taped to a blank piece of paper, with no instructions.
And I bought the steroid Clenbuterol - which is not prescribed in this country for human or even animal use because it causes side-effects such as arrhythmia, the sudden speeding up and slowing down of the heart rate.
Despite all this, within ten days I received the pills, stuck between two layers of masking tape. Again, there were no instructions.
Many anorectic drugs are considered so dangerous they are in the same class as cocaine in the U.S. In Britain, regulations aren't so strict and most, except for Ritalin, are Class C.
Despite the known dangers of these medications, when the Mail contacted the Home Office - which classifies narcotics and misused prescription drugs - it said it was an issue for the Department of Health.
The Department of Health said diet pills are the responsibility of the Medicines and Healthcare Products Regulatory Agency (MHRA).
Although the MHRA is investigating a number of British-based pharmacies for selling prescription medication online, the majority of these drugs are imported from foreign sources, via the postal service, which, they say, makes it an issue for the Home Office and Customs.
They all agreed it was "a bit of a grey area".
In the meantime, websites continue to sell miracle pills to women across Britain, promising them an easy way to lose weight, when in reality there is no such thing.
