[← Back to the Medical Applications Summary Hub](https://cedclinic.com/topic-medical-applications/)Diagram & referenceA visual reference. The evidence, sources and clinical interpretation are in the linked article.About this diagramA single bar chart comparing the ratio of total THC to CBD in two states, fed and fasted. The left bar is the fed condition and the right bar is the fasted condition, with the vertical axis running from 0 to 10. The fasted bar stands far higher than the fed bar, so the shape to take away is that eating narrows the gap between the two cannabinoids. The plotted values are reproduced from the original chart and are shown here as published.The evidence behind it[Read the evidence: what pharmacokinetic trials found about taking cannabis with food and when cannabinoid levels peak](https://cedclinic.com/taking-cannabis-with-food-thc-cbd-levels/)That article carries the cited studies, the limits of the evidence, and the clinical interpretation.
