CBD, along with cannabinol (CBN), was among the first cannabinoid molecules discovered in 1940 and is one of a family of over 113 different chemical compounds called cannabinoids which are naturally produced within the tiny hair-like structures known as trichomes which grow on hemp and cannabis.
Outside of tetrahydrocannabinol (THC), the psychoactive substance found in high concentrations in marijuana, CBD is the beneficiary of the second largest body of research on the medical effects of cannabinoids including its use as an anticonvulsant (antiseizure), anti-inflammatory, antipsychotic, neuroprotector and immunomodulator. And that research is growing.
However unlike THC, CBD is non-psychotropic meaning it does not result in feelings of euphoria. In other words, it will not get you high. CBD is also non-psychotoxic meaning it does not have a detrimental effect on a person’s mind, personality or behavior.
The WHO (World Health Organization) recognizes CBD as being safe, non-toxic and with little to no side effects making it a safe alternative to synthetically derived options which have substantially less clinical data in their support. Although the endocannabinoid system is linked to a number of crucial processes involving the brain, nervous system and reproductive organs, it does not affect regions of the brain controlling heart and lung function.
This is one of the main reasons why it is virtually impossible for fatal overdoses of cannabis or cannabinoids to occur. That being said, consult your doctor if you plan on taking more than 300mg in a 24 hour period.
