Cannabis has two different types of species that have many theories to their respective gene pools of why they evolved in nature. The first is cannabis sativa, and the second is cannabis indica. When these two plants are crossed genetically, they produce strains known as hybrids.
Cannabis sativa typically possesses the following effects on the body and mind making it the perfect daytime medication: physical energy, uplifting mental energy, introspective cerebral thoughts, helps balance mood disorders, creative energy, antidepressant, increased alertness and stimulation of appetite.
Cannabis indica typically possesses the following effects on the body and mind making it the perfect nighttime medication: induced relaxation, narcotic pain relief, sedation of the body and mind, anti-anxiety, reduces nausea, controls muscle spasms, aids in controlling seizures and also stimulates appetite. The effects of hybrids depend on the parent plants and what traits were considered favorable then stabilized during the breeding process.
