Cannabis, CBD, and sleep: what a tracker cannot conclude.

People use cannabis and CBD for different reasons, with different products, doses, medications, health histories, and local laws. A bedtime impression, a wearable score, or a SomniSense reading cannot settle whether a product is safe, effective, or appropriate for you.

If a clinician recommended or supervises its use, that clinical context takes priority over a consumer tracker. Do not start, stop, or change a medical product based on BRI, SRI, sleep stages, or a tagged-night comparison.

What SomniSense can record

You may choose to tag a routine and compare tagged with untagged nights. The app can show sample sizes and whether its own acoustic observations differed between the two groups.

That comparison does not measure dose, blood concentration, sleep architecture, oxygen, airflow, impairment, interactions, or the mechanism behind a difference. It also cannot establish efficacy or safety.

How to keep the observation honest

• Keep the phone position and recording conditions reasonably similar.
• Make the tag specific enough that you know which nights it describes.
• Show the sample count and repeat the observation before giving one night extra weight.
• Describe a difference as an association in your own app record, not a treatment effect or physiological explanation.
• Bring medication, safety, or persistent symptom questions to a qualified clinician.
