Can you read?
From the article: "Ethylene oxide is highly toxic – it causes cancer, it damages DNA – and it is found on the Covid test swabs.
The test swab enters your nose, is rubbed against the nasal mucosa (which has a rich blood supply), removed and then subject to the Covid-19 test.
I may remind you that this is why cocaine users "inhale" cocaine into the nasal chambers for rapid access to the users' systemic circulation.
It sounds a lot to me like they’re looking at the test swabs AFTER they have been tested.
They’re just Q-tips. Replaceable by ordinary q-tips if one is that paranoid.
