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.
A mouth spray might contain 2.7 milligrams of THC and 2.5 milligrams of CBD at doses of 2.5-120 milligram for up to eight weeks. Patients typically use eight sprays within any three hours, with a maximum of 48 sprays in any 24-hour period. To treat schizophrenia: 40-1,280 mg CBD by mouth daily for up to four weeks.
