Both species of the cannabis, indicas and sativas contain similar characteristics of cannabinoids but in different proportions. Higher terpene levels in a cannabis joint are responsible for the couch lock sensation.
In addition to the cannabis strain named Couch Lock. Couch lock also refers to feeling so relaxed and calm that you feel like you literally can’t get up off the couch.
