Cannabis as Medicine? Overview

It is utterly mind-blowing that people have no idea that Cannabis has been part of the medical prescription landscape for over 20 years. That’s right T. G. A (Therapeutic Goods Administration) trialled and approved cannabis based medicines have been available as an option to alleviate, if only in small ways, some of the symptoms of a couple of diseases or help with recovery from treatment. However, the claims of this plant being a ‘miracle cure’ for just about everything, have existed for of 100 years… yet in no credible and advanced research has any of the properties of the Cannabis plant ‘cured’ anything, ever!

There is no argument that some components of this incredibly complex plant can have some therapeutic benefit, be it ever so small, but deriving such from the plant with out co-opting some of the more detrimental components has proven incredibly difficult. On top of that, the evidence emerging from latest science, sees that some of these therapies, do more harm than good, with the temporary alleviating of a symptom on one hand, and incurring along term genetic harm on the other!

Again if facts and evidence matter to your best-practice health care, then this is the space for you. Make informed decisions based on science, and not quackery!

Abstract

Liver safety concerns were raised in randomized controlled trials of cannabidiol (CBD) in patients with Lennox‐Gastaut and Dravet syndromes but the relevance of these concerns to healthy adults consuming CBD is unclear. The objective of this manuscript is to report on liver safety findings from healthy adults who received therapeutic daily doses of CBD for ~3.5 weeks and to investigate any correlation between transaminase elevations and baseline characteristics, pharmacogenetic, and pharmacokinetic data. Sixteen healthy adults were enrolled in a phase 1, open‐label, fixed single‐sequence drug‐drug interaction trial to investigate the effect of repeated dose administration of CBD (1500 mg/day) on cytochrome P450 (CYP) 1A2 activity. Seven (44%) participants experienced peak serum alanine aminotransferase (ALT) values greater than the upper limit of normal (ULN). For 5 (31%) participants, the value exceeded 5× ULN, therefore meeting the international consensus criteria for drug‐induced liver injury. There was no correlation between transaminase elevations and baseline characteristics, CYP2C19 genotype, or CBD plasma concentrations. All ALT elevations above the ULN began within 2–4 weeks of initial exposure to CBD. Among the 6 participants with ALT elevations who were discontinued from the protocol, some had symptoms consistent with hepatitis or hypersensitivity.

We conclude that healthy adults consuming CBD may experience elevations in serum ALT consistent with drug‐induced liver injury. Given the demonstrated inter‐individual variation in susceptibility, clinicians should be alert to this potential effect from CBD, which is increasingly available in various non‐prescription forms and doses to consumers.
