To decide between these hypotheses, we need evidence that cannabis use preceded the psychosis; that plausible alternative explanations based on confounding can be excluded (Hall, 1987). The best evidence for answering these questions comes from longitudinal population-based studies that have assessed cannabis use before the onset of psychotic symptoms, followed the cohort over a substantial period and used statistical methods to assess the contribution of a variety of factors other than cannabis use that may explain the relationship (Macleod et al., 2004).

Cannabis has held sacred status in several religions. It has been used in an entheogenic context – a chemical substance used in a religious, shamanic, or spiritual context - in the Indian subcontinent since the Vedic period dating back to approximately 1500 BCE, but perhaps as far back as 2000 BCE. There are several references in Greek mythology to a powerful drug that eliminated anguish and sorrow. Herodotus wrote about early ceremonial practices by the Scythians, thought to have occurred from the 5th to 2nd century BCE. In modern culture the spiritual use of cannabis has been spread by the disciples of the Rastafari movement who use cannabis as a sacrament and as an aid to meditation. The earliest known reports regarding the sacred status of cannabis in the Indian subcontinent come from the Atharva Veda estimated to have been written sometime around 2000–1400 BCE.
CBD content in Hemp oil, when extracted from the proper strains, can be very high as Hemp plants are now the very strains that are being used to breed high CBD levels back into Cannabis after years of selective recreational breeding for high THC values. Well known strains such Charlotte's Web are hybrids that were selected from crosses with High CBD Hemp varietals and those Hemp genetics are what account for the new High CBD Strains of Marijuana and commercial Hemp that have and are being developed.
In this report, researchers reviewed 16 previously published studies testing the use of various cannabis-based medicines in the treatment of chronic neuropathic pain and found some evidence that cannabis-based medicines may help with pain relief and reduce pain intensity, sleep difficulties, and psychological distress. Side effects included sleepiness, dizziness, mental confusion. The authors concluded that the potential harm of such medicines may outweigh their possible benefit, however, it should be noted that the studies used a variety of cannabis-based medicines (e.g. inhaled cannabis and sprays and oral tablets containing THC and/or CBD from plant sources or made synthetically), some of which are more likely to result in these side effects than products without THC.
