The long term relationships the company has with drug testing labs like Alcopro and ARCpointlabs are valuable. New sweat applications are in the news daily as you point out.
So a company, maybe not the one below, but certainly others, may not need to build a new mousetrap. Ours will do the job. And we have the labs to test for them. These could be factors in PCHM as a takeover candidate.
Talk of a new toxicologist, testing for other substances, new assays, first time investments in R&D, that's the kind of stuff that fits in with what you are saying. This kind of upside it worth waiting for.
