Several studies have pointed out a correlation between the occurrence of OCD and cannabis use (De Alwis et al., 2014; Bidwell et al., 2014; Loflin et al., 2014).
However, whether cannabis use precipitates OCD or cannabis is used to self-medicate against the symptoms of OCD remains to be elucidated.
In one study in mice, CBD, but not CBDV, THCV or CBG, effectively suppressed obsessive compulsive behavior (marble burying)(Deiana et al., 2012).
Interestingly anandamide can inhibit marble burying behavior (OCD) at low doses (1-10 microgram/mouse ICV) via stimulation of CB1, while stimulating obsessive behavior at high doses (20/40 microgram/mouse ICV) via stimulation of TRPV1 (Umathe et al., 2012).
Thus stimulation of CB1 and/or inhibition of TRPV1 might both be beneficial in the treatment of OCD.
