This rapid test is made for the semi-quantitative detection in human urine of THC (marijuana, cannabis)

3 levels of detection in a single test !

This test does not only deliver a simple positive or negative result.

It shows in addition if the concentration of THC in urine is LOW, MEDIUM or HIGH.

This test is particularly effective over time. Initial screening will serve as a baseline, while the tests that follow will see the lowering or raising level of THC in urine. By practicing regular screenings, it is now much easier to see if the subject has stopped its consumption (steady decrease in the level of THC) or if he can get re-smoking (sudden increase in the level of THC).

A new tool to assist a patient or the progress of a withdrawal.

The advantages of THC PreDosage:

    Encourage and motivate those who decide to give up marijuana is an integral part of the assistance they need. This is one of the major advantages of this test: it allows the patient to see by himself that his metabolism is eliminating the residues of THC. Efforts are therefore represented by a real and practical tool, which helps to maintain motivation, because it is possible to say “Look, your efforts are useful! Your THC is decreasing. Hang in there, it works!

  • React quickly: the NarcoCheck THC PreDosage test allow to maintain a vigilance by monitoring the regression of THC in urine. During this process, if the THC level is suddently raising, this could indicate a possible relapse, so a medical reaction can take place without wasting time. Conversely, if the withdrawal is met, the former consumer will see its positivity to THC reducing level by level to achieve a completely negative test after a few weeks. This first full negative test can also be used as a real psychological help for the patient, because keeping it may symbolize the detoxification of his body and the victory over addiction.
  • This test can detect the presence of any cannabinoid :

    • Marijuana (indoor or outdoor weed)
    • Cannabis resin, also known as hashish
    • Cannabis oil (rarely used)

    It is effective whatever the mode of consumption :

    • In joints (marijuana cigarettes).
    • By inhaler, bang etc.
    • In infusion or culinary preparations like cakes (also called “space cake”)

    Argentina to Allow Medicinal Marijuana to Be Grown at Home

    The new regulation also orders insurance providers to cover cannabis products prescribed by doctors. Some of the strongest champions of the government’s move were mothers of sick children.

    BUENOS AIRES — Argentina on Thursday authorized people to grow marijuana at home for medicinal use, delighting supporters of cannabis who have fought for years to make it widely available to patients suffering from a broad range of ailments.

    A decree issued by President Alberto Fernández also allows pharmacies to sell cannabis-derived oils, creams and other products, and it orders public and private insurance systems to cover these medications for patients who obtain a prescription.

    The president’s move significantly expanded the reach of a 2017 law that legalized medical marijuana. Supporters of medicinal cannabis say Mr. Fernández’s predecessor, Mauricio Macri, established restrictions so strict that it effectively made the drug inaccessible to patients.

    The measure is the latest step softening drug laws in Latin America. In 2017, Uruguay legalized recreational marijuana, which is sold in pharmacies, and Colombia established a licensing system to grow cannabis for medicinal use. Home growers in Argentina will need a license based on medical needs.

    “We’ve been fighting for this for three years,” said Valeria Salech, the head of Mamá Cultiva, an Argentine organization that promotes medical marijuana. “We’re no longer going to be criminalized for seeking a better quality of life for ourselves and our loved ones.”

    Ms. Salech became a strong proponent of medical marijuana when she saw the positive effects cannabis oil had on her son, Emiliano, who has epilepsy and is autistic. Emiliano, now 14, has been using cannabis oil for the past six years.

    “Cannabis helped him improve his connection to those around him. He was able to stop using diapers, to pay attention, he learned how to play,” Ms. Salech said. “It changed our lives.”

    The 2017 law was so restrictive that people mainly acquired cannabis products on the black market.

    “There was a law but there was no access to products,” said Argentina’s health minister, Ginés González García. “We are replacing a black market that already exists with quality control that is key in all medical products, particularly those that are given to children.”

    The 2017 law permitted only patients with refractory epilepsy access to cannabis oil, and there was no procedure in place to obtain it legally through the state. Ms. Salech and other activists encouraged cannabis users to grow their own plants, despite the fact that doing so was against the law.

    “We cultivate knowing that at any moment we could lose our freedom, but we do it because you can’t put a price on quality of life,” Ms. Salech said.

    Growing marijuana carried with it prison terms of between four and 15 years. Those who grow it going forward without a license will still face that penalty.

    The government now intends to draw up a licensing system to authorize home cultivation. It also hopes to work with medical laboratories interested in producing marijuana and its derivatives.

    Approval will be “on a case-by-case basis,” Mr. Gonzaléz García said, but he emphasized there will be a broad understanding of the pathologies that could be helped by cannabis.

    “Even if it does not provide a cure, improving quality of life is no small thing,” he said.

    Argentina’s new regulation will also allow cultivation by third parties who are growing cannabis on behalf of those with a medical need.

    For now, full legalization of marijuana is not on the government’s agenda. But activists are optimistic the definition of medical needs will be expanded to include general well-being.

    “If we only think of health as the absence of illness, we’re missing the point,” Ms. Salech said. “This plant came to teach us that.”

    The new regulation also orders insurance providers to cover cannabis products prescribed by doctors. Some of the strongest champions of the government’s move were mothers of sick children. ]]>
