*'''[[Effect::Spontaneous bodily sensations]]''' - The "body high" of cannabis is extremely variable and depends entirely on the individual strain as well as dose and method of intake. In general, however, it can be described as a relatively pleasurable, sometimes warm, soft, intoxicating and all-encompassing sensation. At high dosages, it can cause some users to feel shaky or nerve-wracked.

====Hypothetical differences between ''C. indica'' and ''C. sativa''====
====Hypothetical phytocannabinoiod differences between ''C. indica'' and ''C. sativa''====
The effects of ''sativa'' may be used for a high, while ''indica'' may be used for its sedative effects. Both types are used as medical cannabis.
 
*Cannabinoid ratios: On average, ''Cannabis indica'' has higher levels of [[Tetrahydrocannabinol|THC]] compared to [[Cannabidiol|CBD]], whereas ''Cannabis sativa'' has lower levels of THC to CBD.<ref name="Hillig">{{cite journal |author1=Karl W.

=====Criticism=====
In 2022, studies found that plants identified as "indica" or "sativa" based on common methods of differentiation (e.g. plant height or leaf shape) are not, in fact, chemically distinguishable, with many identified as "sativa" having cannabinoid ratios predicted of "indica" plants and vice versa. The authors have concluded that the chemical makeup of cannabis plants cannot be reliably determined by simple inspection of the plants' physical characteristics and that the "indica" and "sativa" labels are not informative as to the cannabinoids (or other chemical components) delivered.<ref>{{Cite journal| doi = 10.1371/journal.pone.0267498| issn = 1932-6203| volume = 17| issue = 5| pages = –0267498| last1 = Smith| first1 = Christiana J.| last2 = Vergara| first2 = Daniela| last3 = Keegan| first3 = Brian| last4 = Jikomes| first4 = Nick| title = The phytochemical diversity of commercial Cannabis in the United States| journal = PLOS ONE| date = 2022| pmid = 35588111| pmc = 9119530| bibcode = 2022PLoSO..1767498S| doi-access = free}}</ref><ref>{{Cite journal| issn = 1664-462X| volume = 13| last1 = Murovec| first1 = Jana| last2 = Eržen| first2 = Jan Jurij| last3 = Flajšman| first3 = Marko| last4 = Vodnik| first4 = Dominik| title = Analysis of Morphological Traits, Cannabinoid Profiles, THCAS Gene Sequences, and Photosynthesis in Wide and Narrow Leaflet High-Cannabidiol Breeding Populations of Medical Cannabis| journal = Frontiers in Plant Science| date = 2022| page = 786161| doi = 10.3389/fpls.2022.786161| pmid = 35283868| pmc = 8907982| doi-access = free}}</ref>
