CBD and terpene blends improved social behavior in an autism mouse model

Both CBD-rich extract and specific terpene blends increased sociability in BTBR mice. The terpene blends alone produced prosocial effects comparable to CBD, suggesting non-cannabinoid cannabis compounds may contribute to social behavior improvements.

Behavioral testing in BTBR mice (an inbred strain modeling autism-like social deficits). Acute administration of CBD-rich hemp extract or terpene blends inspired by cannabis cultivar profiles. Three-chamber social approach test measured sociability and social novelty preference.

Autism spectrum disorder has very few pharmacological treatment options, especially for core social symptoms. If both cannabinoids and terpenes can improve sociability, the active ingredients in cannabis products may be broader than THC and CBD alone.

The idea that terpenes contribute to cannabis effects (the "entourage effect") has lacked rigorous evidence. This study provides some of the first controlled data suggesting terpenes alone can produce behavioral effects relevant to neuropsychiatric conditions.

Mouse model of autism has limited translational relevance to human ASD. Acute dosing only; no chronic administration data. BTBR mice have specific genetic characteristics that may not reflect the diverse biology of human autism. Terpene blends were inspired by cannabis but not identical to natural plant ratios.
