ABSTRACT
BACKGROUND AND OBJECTIVES:
The use of cannabis for medical purposes is known since ancient times. The endocannabinoid system is present throughout central and peripheral nervous system and plays a role in many important regulatory physiological processes like immune function, synaptic plasticity, pain and regulation of stress and emotion, among others. Due to its wide distribution and according to researches, cannabis can be indicated for symptoms management in different disorders such as chronic pain, headache, epilepsy, anxiety and other psychiatric disorders. The primary cannabinoids studied to date include delta-9-tetrahydrocannabinol (THC), cannabinol (CBN), cannabigerol (CBG), and tetrahydrocannabivarin (THCV). The active ingredients in cannabis include flavonoids, terpenes, delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD) and they are able to act within the endocannabinoid system and decrease nociception and also the frequency of the symptoms. The purpose of the article is to document the validity of how medical cannabis can be utilized as an alternative therapy for chronic headache management and enlighten about false beliefs regarding its use.
