Cannabis myths fact-checked
Four key cannabis myths, checked against tier-A studies. Each page gives the short answer, what the evidence actually shows, and why the myth holds on. More to follow as the sources come together.
Indica makes you sleepy, Sativa keeps you awake. Is that true?
No, at least not the way the rule of thumb claims. The distinction comes from 18th-century botany and describes how the plant grows, not how it acts. Eight PubMed sources, one dogma fewer.
Read the fact check → MythDoes THC content tell you everything about the effect?
No. THC is the dominant psychoactive compound, but the effect you feel hangs on the whole profile. Two strains with an identical 25% THC can act completely differently, depending on the terpene profile and CBD ratio.
Read the fact check → MythOne terpene = one effect
The simple version of that sentence is wrong. Terpenes are pharmacologically active, but the idea that each terpene = one fixed effect does not hold up in the research. Eight PubMed sources, multi-target explained.
Read the fact check → MythTerpenes are harmful to health. Is that true?
No, not as a rule. Terpenes are a class of compounds. The FDA and JECFA rate individual ones like limonene and linalool as safe at flavoring amounts. The real risks lie in concentration, oxidation, swallowing, or heavy heating, not in the terpene itself. Eleven tier-A sources, one category error resolved.
