The symptoms of Aleksey Navalny’s alleged poisoning are absolutely uncharacteristic of the use of the Novichok nerve agent. He would have suffered convulsions and died, instead of falling into a coma.
There is no way Navalny was poisoned by this neurotoxic agent. The fact that Russian opposition figure Alexei Navalny was put out of coma indicates that it was not Novichok nerve agent used against him.
Novichok was developed to replace nuclear weapons on the battlefield and has 100% mortality.
This argument follows a recurring Kremlin pattern of denying that Navalny was poisoned and that Moscow had anything to do with it. In this case, the argument is that Novichok is only a lethal military-grade nerve agent and that the result is always death. However, we know that Novichok is a highly toxic nerve agent that slows the heart, paralyses the muscles used for breathing and — if the dose is big enough — can lead to death by asphyxiation. A smaller dose may result in seizures, neuromuscular weakness, liver failure and other damage. This has been presented in various other reports here, here and here. So, Novichok does not necessarily lead to the death of everyone who came in contact with it.
Navalny's coma was medically induced and did not constitute a symptom of poisoning. Several other confirmed Novichok victims were put in a coma and subsequently regained consciousness. In 1987 Andrey Zheleznyakov, a researcher attached to the Soviet chemical warfare programme, suffered an accidental exposure to a Novichok-type compound. The accident left him permanently disabled but alive for another six years.
In March 2018, Russian ex-spy Sergey Skripal and his daughter Yuliya fell victim to poisoning in Salisbury but recovered with intensive medical care as did a police officer who had been exposed when he visited their home to investigate. The UK authorities established that the assassination attempt had been carried out by two Russian intelligence operatives using Novichok.
The following June, two individuals in Amesbury, England were accidentally exposed to Novichok contained in a fake perfume bottle. One of the victims survived.
It should be further noted that, like most other chemical weapons, Novichok was not developed with the individual assassination in mind. Marc-Michael Blum, former head of the OPCW Laboratory, explains that "these substances are designed for the mass destruction of enemy personnel during war," and are thus "not reliable enough" if used to kill one, specific individual in peacetime conditions. In other words, it cannot be ruled out that Navalny was poisoned by Novichok simply because he survived the ordeal and regained consciousness.
