I made this comment https://old.reddit.com/r/Crainn/comments/1fr9f36/does_hhc_show_up_in_roadside_tests/lpf891g/ ~7months ago  on a now deleted thread. It may or may not be viewable for some on that link so I'll copy and paste it here:

The first thing to realise is there is a lot of nuance to the situation.
A lot of comments on this sub say that you will get a conviction as HHC will show up as THC anyways. This is not factual information as I will demonstrate...
Have a look at this comment I made related to this issue. https://old.reddit.com/r/Crainn/comments/1avkxjz/drug_wipe/krbi6ta/
The crux of the issue is whether the HHC product you're consuming has trace amounts of THC. If you're consuming CBD flower sprayed with HHC concentrate then we know that flower has trace amounts of THC - typically 0.2%.

I made about consuming CBD bud that proves you need to be careful smoking it. This was a study carried out on non-regular smokers vs chronic smokers so it holds weight.
As for what you can consume and not have to worry...It seems vaping HHC might be fine.
Here's my logic:
I'm going to presume the people described in this study from 2024
https://pubmed.ncbi.nlm.nih.gov/38581662/
mostly consumed HHC through vapes but there's surely a couple that smoked regular HHC/CBD flower but enough time had elapsed for the trace amounts of THC to leave their system while the relative high concentration of HHC remained.
So to summarise this study:
Drivers had been screened with a roadside device that indicated the presence of cannabis in the saliva sample.
A blood test was then carried out and no THC was found so they would not have been convicted under Irish legislation.
At some point later these researchers used these blood samples to check if they could find HHC as the roadside device had indicated cannabis was present and I guess they wanted to get to the bottom of it whether it was just to come up with a definitive test for the presence of HHC or whatever, I don't know.
There's revealing information in the abtract of the study...
Blood samples from driving under the influence of drugs (DUID) cases screened positive for cannabis using enzyme-linked immunoadsorbent assay (ELISA) and confirmed negative for tetrahydrocannabinol (THC), 11-hydroxy-THC and THC-COOH were reanalyzed with a newly validated HHC method to investigate the presence of HHC and metabolites
So these drivers were positive for HHC but not THC...
If the THC and HHC metabolites were the same, they wouldn't make this distinction. But we didn't need this study to tell us that. Googling their chemical makeup and metabolites would tell you that already.
It was determined that the major metabolite in blood after administration of HHC was 9R-HHC-COOH followed by 11-OH-9R-HHC and that presumptive positive cases are caught by the routine ELISA screening for cannabis.
They state the exact metabolites of HHC here and that they can use what's called an immuno-assay to determine with high confidence that metabolites of HHC are present in the blood sample. So again, the metabolites cannot be the same...

Here's a previous post I made regarding smoking CBD bud:

And here's another comment from that thread specifying why exactly the tests have the sensitivities they have...

It's not actually about proving impairment, it's about getting "results".
And remember there is an EU directive called Vision Zero which means testing on the roadside is only going to get more invasive over time, even when cannabis is legalised.

This problem of DUID is even more pronounced in Ireland because we have terrible public transport from most locations and the private transport is expensive so that incentivizes people to drive their own vehicles on substances.
I'm not condoning driving on anything, I'm just saying we need to effing get real here, this is absolutely, for want of a better term, a driving factor.
If I'm honest, you're far better off depriving the dealers in Ireland of your money, save your few pound and have a nice weekend to Amsterdam or another smoking friendly location more frequently than going the odd time while subjecting yourself to a bad time dealing with dodgy dealers here
