Evening, I work for TruTag technologies and saw some technical questions on our solution that I can help with.
In the CBD and cannabis space TruTags have been tested on plants, seeds, edibles, isolates and also packaging.
On the question of silicosis - this ailment results from the inhalation of crystalline silica particles that are less than 2 microns in size.
TruTags are made of amorphous silica which does not cause silicosis.
Also our particles are many multiple times larger than a size that is of concern.
Hope this helps.
