The pollutants found in cannabis surveys sold in the Dutch semi -legal “coffee shop” contained lead, pesticides, and potentially harmful bacteria.
of the studyThis study was conducted by the Dutch Mental Health and addiction Research Institute (Trilibos Institute), aimed at establishing a typical “base line” level. I will use it to announce Trial starts in April In this plan, 10 municipal stores will be produced by approved cultivated, and will sell cannabis, which is subject to contaminants.
Researchers tested 50 cannabis samples, including both resin and cannabis purchased from the seller chosen randomly. One in five samples contained the following “intrusion of microorganisms”. Staphylococcus aureus Approximately one -third of the bacteria or fungi residues and pesticides were found. One hassample contained about 6 times the amount of lead (28.5 mg/kg) of the amount allowed by cannabis sold during the test.
“Yes, cannabis contains pollutants,” says Peter Omen, an analytical chemist and researcher in the Dutch pharmaceutical market. “I found one sample containing multiple pesticides, multiple microorganisms, and lead.”
Tourists gather in the Netherlands with the impression that cannabis is completely legal, but since 1976. Tolerance policy It just means that the regulated “coffee shop” is allowed to sell hash and marijuana. However, it is illegal to grow more than five plants, so the store must be purchased from an illegal supply company. Concerns about promoting crime。
After the news letter promotion
The regulated cannabis trial aims to block criminal circuits and reduce pollution. The ten producers have undergone criminal tests and will be given permission to supply cannabis to the coffee shop participating in the trial. Four are now ready to supply. Their agricultural products are inspected and confirmed that they have not exceeded the restrictions on pollutants, such as harmful aflatoxins produced by heavy metals, microorganisms, pesticides, and fungi.
In research, potentially harmful Staphylococcus aureus Bacteria indicated that the hygiene level was inappropriate at all stages of cultivation, trimming, packaging, and sales.
Omen said this small study is “explorable” and does not mean that all the nuts can be contaminated. The study concluded that the harm may be relatively minimal, especially when combined with cigarettes, compared to the effects of smoking joints first.
“It is difficult to interpret the microorganism pollutants we discovered, because the impact depends greatly on the immune system of the person who consumes cannabis,” he says.
“We don't think that the pollutants we discovered would only increase the risk that someone is already implementing just by using the cannabis itself. Acute effect is anxiety, panic, and traffic. Basically, there is a possibility of alerts, such as addiction, and if you don't want to expose your health.
