Key takeaways

What to know first

  1. 1

    Research on Overall sleep disturbance covers CBD and CBN; those areas should not be combined into one claim. 1

  2. 2

    Human research is included, although its design and scope vary. 2

  3. 3

    Dose, formulation, route, study population, and outcome can change how closely a study applies to a real-world question. 1

Research areas

What researchers studied about Overall sleep disturbance

These are the main questions represented in the current literature. Each link opens a source used to build the overview.

Human research included

CBD

Researchers have studied CBD in connection with Overall sleep disturbance. The exact compound, dose, formulation, sleep or health measure, and study design determine what the source can show. 1

Human research included

CBN

Researchers have studied CBN in connection with Overall sleep disturbance. The exact compound, dose, formulation, sleep or health measure, and study design determine what the source can show. 2

Results extracted so far

What did the studies report?

These summaries appear only when the recorded study outcome is specific enough to reproduce from the linked source. If a source has no result summary here, the result has not been extracted yet; that does not mean the study found no effect.

clinical study in people

A double-blind, randomized, placebo-controlled study of the safety and effects of CBN with and without CBD on sleep quality

6 recorded findings

PubMed 37796540

  • In a double-blind randomized placebo-controlled study involving adults 18-55 with poor self-rated sleep quality, researchers reported fewer nighttime awakenings following 20 mg CBN over 7 nights. The recorded comparator was placebo. 1

  • In a double-blind randomized placebo-controlled study involving adults 18-55 with poor self-rated sleep quality, researchers reported lower overall sleep disturbance following 20 mg CBN over 7 nights. The recorded comparator was placebo. 1

  • In a double-blind randomized placebo-controlled study involving adults 18-55 with poor self-rated sleep quality, researchers did not detect a difference in sleep onset latency following 20 mg CBN over 7 nights. The recorded comparator was placebo. 1

  • In a double-blind randomized placebo-controlled study involving adults 18-55 with poor self-rated sleep quality, researchers did not detect a difference in wake after sleep onset following 20 mg CBN over 7 nights. The recorded comparator was placebo. 1

  • In a double-blind randomized placebo-controlled study involving adults 18-55 with poor self-rated sleep quality, researchers did not detect a difference in daytime fatigue following 20 mg CBN over 7 nights. The recorded comparator was placebo. 1

  • In a double-blind randomized placebo-controlled multi-arm trial involving 293 adults with self-rated poor or very poor sleep quality, researchers did not detect a difference in augmentation of cbn sleep effects following 20 mg CBN with 10 mg, 20 mg, or 100 mg CBD nightly by the not stated in the PubMed abstract route over 7 nights. The recorded comparator was 20 mg CBN alone and placebo. 1

    Recorded result: Adding CBD did not positively augment the CBN treatment effects.

clinical study in people

A Randomized, Double-Blind, Placebo-Controlled Trial to Assess the Effectiveness and Safety of Melatonin and Three Formulations of Floraworks Proprietary TruCBN for Improving Sleep

1 recorded finding

PubMed 39204082

  • In a decentralized randomized double-blind placebo-controlled trial, researchers reported lower overall sleep disturbance following 25 mg, 50 mg, or 100 mg oral CBN formulation. The recorded comparator was placebo and 4 mg melatonin. 2

How strong is the research?

Not every study answers the same question

This page separates research in people, research reviews, and earlier-stage biology before interpreting the larger question.

2 sources

Human studies

Research involving people is closest to everyday health questions. The product, dose, population, and outcome still determine what each study can show.

Not prominent

Reviews and evidence summaries

Reviews can compare several studies at once. Their conclusion is only as strong and as relevant as the studies they include.

Not prominent

Lab, animal, and mechanism research

Early-stage research can explain biological interest. It cannot, by itself, show that the same effect happens in people.

What these studies actually looked at

The research on Overall sleep disturbance is not one kind of study. This source set includes 2 clinical studies in people. 1

The recorded populations or models include 293 adults with self-rated poor or very poor sleep quality (1 source), adults 18-55 with poor self-rated sleep quality (1 source), and people or patients (1 source). A result from one group or model should not be assumed to apply to another. 2

The most common recorded outcome focus is daytime fatigue (1 source), number of awakenings (1 source), and overall sleep disturbance (1 source). Closely related outcome names can still describe different measurements. 1

Some source records specify doses including 20 mg CBN (1 source), 20 mg CBN with 10 mg, 20 mg, or 100 mg CBD nightly (1 source), and 25 mg, 50 mg, or 100 mg oral CBN formulation (1 source). These are descriptions of what researchers tested, not personal dosing instructions. 2

Safety and limits

What should readers keep in mind?

Research on Overall sleep disturbance should be read beside safety. A compound can be non-intoxicating or naturally occurring and still have pharmacologic effects, side effects, interactions, or product-quality concerns. 2

Research doses are descriptions of what a study tested. They are not personal dosing instructions. Questions involving medications, pregnancy, children, driving, liver health, heart health, or serious symptoms deserve professional medical guidance.

Common questions

Questions people ask

Can cannabinoids help with Overall sleep disturbance?

Research exists, but there is not one answer for every cannabinoid or product. Human research is included, although its design and scope vary. 1

Why can studies reach different answers?

Studies may test different cannabinoids, doses, formulations, routes, people, and outcomes. Those differences can change the result. 2

What should I check in a study?

Check whether it studied people, what product and dose it used, what it measured, how long it lasted, and whether safety was reported. 1
