"Theragrippers" are tiny, shape-changing machines that deliver medicine efficiently to the GI tract.

The "theragrippers" are made of metal and a thin, shape-changing film, then coated in heat-sensitive paraffin wax. The devices, each roughly the size of a dust speck, can potentially carry any drug and release it gradually into the body.

Still haven't been tested and won't ever take one. Not much we can do if they aerosol it.

When testing is required again, only do the saliva method, possibly blood drawn.

Saliva is just spitting into a container and you give it to them once you fill it up to the line.
