How much endocannabinoid science is there and how influential is the research field?

Title-based Bibliometric Analysis (PubMed and Google Scholar)

Physiological System	Title-based Publications (PubMed)	Total Citations* (Google Scholar)	h-index* (Google Scholar)
Endocannabinoid System	1,299	84,521	142
Digestive System	1,072	41,917	80
Immune System	8,256	366,238	314
Endocrine System	384	25,570	78

Respiratory System	934	35,628	83
Lymphatic System	422	23,885	76
Nervous System	1	336,911	306

This analysis gives us a rough idea of how many scientific articles have been published with different physiological systems present in their titles between 2004-2024.

The h-index and Total Citations provides us with numbers that show how influential the research fields have been. It is evident that endocannabinoid science is not only an active research field, but also an influential research field, boasting higher numbers than half of the other well-recognised physiological systems.
