Introduction

α2 receptors are classically known as adrenalin receptors. However, α2 receptors also bind CBG at very high affinity and are therefore also Cannabinoid receptors. The interaction between CBG and α2 receptors may be relevant in the treatment of pain and depression, but more research is required.

Literature Discussion

depression

CBG can activate α2 receptors and block CB1 and 5-HT1A receptors (Cascio et al., 2010), suggesting CBG does have therapeutic potential in the treatment of depression.

pain

The interaction between CBG and the α2 receptor (alpha 2 adrenalin receptor) may prove effective in pain control (Giovannoni et al., 2009).
