Epilepsy is considered to be one of the most common non-communicable neurological diseases especially in low to middle-income countries. Approximately one-third of patients with epilepsy have seizures that are resistant to antiepileptic medications. Clinical trials for the treatment of medically refractory epilepsy have mostly focused on new drug treatments, and result in a significant portion of subjects whose seizures remain refractory to medication. The off-label use of cannabis sativa plant in treating seizures is known since ancient times. The active ingredients of this plant are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), the latter considered safer and more effective in treating seizures, and with less adverse psychotropic effects.
Astronauts have taken medication to space since the early days of off-planet exploration—but next spring, a Colorado company plans to be the first to send plant cultures of coffee and hemp, a variety of marijuana, to the International Space Station (ISS). The mission will test if zero gravity will mutate or genetically alter the plants, so presumably someday you can have a CBD-infused coffee on Mars.
