Breathalysers offering changeable sensors avoid you having to send the complete breathalyzer back to a service centre
Breathalyzers taking mouth pieces give more accurate results than “blow at the hole” models
Breathalyser should take standard batteries
Buy from a reputable established breathalyzer dealer, your warrantee is with the UK supplier.
I recommend avoiding key ring and micro breathalyzers. They are not reliable for long periods, and are unlikely to be cost effective to service, so these very cheap breathalyzers should be viewed as consumable novelty items. I would not personally rely on one!
Ecstasy really is in the news this weekend. Read this article today in the Guardian
Sales of ecstasy in powder form make it increasingly difficult for drug takers to know what mind-altering substance they are consuming, a senior government adviser warned yesterday.
A rise in the importation of high-purity powder or crystal ecstasy has led to clubbers confusing it with cocaine, the Advisory Council on the Misuse of Drugs (ACDM) heard at an open session reviewing legal classification.
Prof David Nutt, the council’s incoming chairman, said: “If you are buying white powders from someone, how do you know if you are getting MDMA [ecstasy’s main ingredient], methamphetamine or cocaine? It’s potentially very dangerous.” Powdered ecstasy was “massively more powerful” than tablet form.
Dr Paul Dargan, head of the poisons unit at Guy’s and St Thomas’s hospital, told the meeting: “We see a lot of patients who have taken powder they think is cocaine but was actually MDMA.
Read this interesting article online by Colin Blakemore that I thought may be of interest to you. It is about the classification of drugs including ecstasy (ecstasy is currently a Class A drug ) and he concludes that ‘No drug is completely safe, but ecstasy does not destroy the brain and is not exceptionally toxic’
Current UK guidelines recommend that women limit their intake to two or three units a day. You shouldn’t save up units through the week and use them to binge at the weekend, and at least one day a week should be alcohol-free.
Strength and units
One unit is 8 grams, or about 10ml, of pure alcohol – regardless of how diluted it is. Below is a list of some common drinks and how many units they have in them.
One pint of strong lager (alcohol 5% vol) = 3 units
One pint of standard strength lager (alcohol 3 – 3.5% vol) = 2 units
One 275ml bottle of an alcopop (alcohol 5.5% vol) = 1.5 units
One standard (175ml) glass of wine (alcohol 12% vol) = 2 units
One measure (25ml) of a spirit strength drink = 1 unit
The recommended limits are lower for women than for men because the body composition of women has less water than men. So, even if a man and woman weigh the same and are of a similar size, the woman will tend to get drunk faster.
Some experts also think that women develop liver disease at lower levels of drinking than men, although this appears to only be the case in higher levels of alcohol consumption.
Alcohol & Pregnancy
Women who drink heavily during pregnancy are at risk of having babies with a condition called fetal alcohol syndrome. This can result in growth deficiencies, nervous system problems, lowered intelligence, and facial abnormalities in the child. It is also called fetal alcohol spectrum disorder – all the symptoms are not always present and can vary in how serious they are.
There is some evidence that pregnant women who drink 10 to 15 units a week are more likely to have underweight babies. It is not known if there is an absolutely safe limit for drinking during pregnancy, but research indicates that it may be wise to avoid alcohol altogether.
Cannabis is fat soluble, so over sustained regular use it is deposited around the body and can take several weeks, too a month to be excreted. In practice this only occurs in heavy regular consumers of cannabis, usually the concentrated forms such as skunt, and for most irreglular or occassioanl users THC will be excreted much quicker.
Dose size and route of administration are among the factors which determine the period after use during which the drugs or metabolites might be detected in a urine sample. As these are almost always “unknown” all drug detection periods are normally given as a window and will cover around 90% of cases.
Amphetamine 3-5 days
Barbiturates 1-5 days (longer for Phenobarbitone)
Benzodiazepines 2-30 days depending on half live of drug
Passive inhalation is sometimes put forward as a reason for a positive cannabis drug testresult. Extensive Research has shown that this is improbable. As an example, in one study volunteers were exposed to smoke from cigarettes containing a known concentration of THC (the active ingredient of cannabis) over six one hour periods. The smoke was so intense that the volunteers had to wear goggles. The highest level detected by GC/MS analysis was only one third of the internationally accepted cut-off level for cannabis.
The International cut off levels for urine tests for THC (50ng/ml) are also set well above the level that could possibly be absorbed through passive smoking of THC fumes.
Company magazine, as part of their alcohol awareness campaign, have featured the DA5000 Breathalyserfrom www.valuebreathalysers.co.uk. The breathalyser was used to measure the resultant blood alcohol levels in female consumers of wine. Company hope to draw attention to the move of pubs and restaurants to “large” glasses for serving wine.
Outlets encourage the consumtion of “large” glasses, by refering to standard measure glasses as “small”. Many establishments were also found to defer to the large glass measures if no direct request is specified by the customer at the point of ordering “a glass of wine”
The move away from traditional pub measures has in many cases doubled the alcohol present per glass, leaving consumers under-estimating the quantity of alcohol consumed and its effect.
