Delusional parasitosis, or delusory parasitosis, also known as Ekbom's syndrome, is a form of psychosis. Victims acquire a strong delusional belief that they are infested with parasites, whereas in reality no such parasites are present. Often, exposure to household cleaning products can result in a sensation known as formication.
To treat chronic pain, cannabinoids have been taken by mouth in the form of capsules or sprayed into the mouth as THC, benzopyranoperidine (BPP), cannabidiol (CBD), nabilone, dronabinol, or synthetic nitrogen THC analogs (NIB), with doses of 2.5-20 milligrams for an average of 25 days.
Cannabis plant extracts containing 2.5-120 milligrams of a THC-CBD combination have been taken by mouth daily for 2-15 weeks. A mouth spray (SativexÂ®, containing 2.7 milligrams of THC and 2.5 milligrams of CBD) has been used at a dose of 2.5-120 milligrams in divided doses for up to eight weeks.
