Private substance use screening
Help is here, and it starts in private.

Screening breaks down long before care can start
It isn’t only about clinics and money. Four things keep people from an honest result, and keep results from reaching anyone who can help.
Fear of judgement
People soften their answers when they feel watched. Honest screening needs privacy first.
Nothing to check against
Questionnaires rely on self-report alone, so clinicians have little to weigh it against.
Too few specialists
Trained addiction professionals are scarce, especially outside large cities.
Results that go nowhere
A screening score that never reaches a clinician changes nothing for the person who took it.
Four checks, one report
Powered by a trained LLM, Menlumin combines what you tell it with objective measures, so your result rests on more than one source.
Step 1
Eye scan, if you want it
Your camera photographs both eyes and a model measures pupil size in millimetres. You can skip it.
Step 2
Interactive questions
The WHO’s standard questionnaire covers alcohol, tobacco, cannabis, opioids, stimulants and more.
Step 3
A closer look, if needed
Higher-risk answers lead to further WHO risk questions on medical, legal and psychological areas.
Step 4
Lab check
Upload a urine drug screen and a clinician can see where it agrees with what you reported.
Support that carries on after the result to ensure your recovery and wellbeing
