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.
I find 20 mg of CBD to be a low dose. I like to dose with 40mg CBD and 10mg thc, it's the perfect amount and the perfect ratio for me.
