Taxane-induced peripheral neuropathy (TIPN) is experienced by most patients with breast cancer, and there is no efficacious treatment. In pre-clinical studies, co-administration of two constituents of cannabis, Δ-tetrahydrocannabinol (THC) and cannabidiol (CBD), synergistically reduces TIPN. The goal of this 8-week, double-blind, randomized pilot study, conducted from 2019 to 2021, was to test the feasibility and tolerability of oral cannabis (100 mg CBD: 5 mg THC, TID) relative to placebo on pain resulting from TIPN.
