Yes. CBD has cannabinoid receptor-independent properties. For example, CBD is an agonist at the TRPV1 receptor and has agonist properties at the 5-HT1A/2A/3A serotonergic receptors. CBD is also a capsaicin analog. CBD has antagonist activity on alpha-1 adrenergic and μ-opioid receptors, too. In addition, CBD has been found to inhibit synaptosomal uptake of noradrenaline, dopamine, serotonin, and gamma-amino butyric acid. CBD also inhibits anandamide uptake.
