Human Effect Matrix
The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect lung function
| Grade | Level of Evidence [show legend] |
|---|---|
|
Robust research conducted with repeated double-blind clinical trials |
|
Multiple studies where at least two are double-blind and placebo controlled |
|
Single double-blind study or multiple cohort studies |
|
Uncontrolled or observational studies only |
|
Level of Evidence
?
The amount of high quality evidence. The more
evidence, the more we can trust the results.
|
Outcome |
Magnitude of effect
?
The direction and size of the supplement's impact on
each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
|
Consistency of research results
?
Scientific research does not always agree. HIGH or
VERY HIGH means that most of the scientific research agrees.

Secondary to treating sickness (bronchitis, URTIs, common cold) there is improvement in sputum content, rhonchi, breathing, coughing, and chest pain while coughing relative to placebo; while the improvements are marked, they only occur secondary to treating illness.

While smoking per se is seen as negative, infusions of THC enhance lung function and acute usage of marijuana as joints seem to confer more benefit to lung function than drawbacks.
