To ask for help reading these?

[DrugTestHelp]

Sorry to post in AIBU but need some help.

Please can anyone help read the attached tests. Assume second line is positive on at least the one on the left?.

Am I right in thinking cocaine?

Also, does the colour of the lines mean anything? (Ie the OPI is completely negative as it’s so dark where as the others are likely to have had some trace) or does it not work like that?

Thins looks like the same test so might give you more info

I previously worked in a substance use support service. My reading of those tests is that the person is negative for opiates (could be heroine, fentanyl, codeine, morphine etc) positive for cocaine, negative for cannabis (THC), amphetamine (speed), methamphetamine and benzodiazepines (could be diazepam, temazpam, clonazapam etc).

It doesn't work like that, it's either in your system or it's not.

It says 2 lines is negative so they're only positive for the second one, and there's possibly a faint line there on the left hand one, it's hard to tell with the shadows.

on the link @jackstini posted it says a faint line is still negative.
I found shining a light from behind helped when I thought I could see a faint line in pregnancy tests

Thanks all. When zoomed in there is actually a very faint line on the cocaine one as well but obviously questionable.
