Yes, CBD oils made from marijuana (sativa or indica) can have higher concentrations of both CBD–as well as CBN and THC (the latter is the “main attraction” because it’s psychoactive). But because not everyone can lawfully buy them (and those who can must purchase in person from a state-licensed dispensary) and they’re not available online except to customers living in certain recreational-weed-legal states, they aren’t being reviewed here. Also, MJ-derived CBD oils are not as widely produced and sold.
In fact, numerous studies have looked at the relationship between CBD and pain, and the results are promising. Researchers have looked at various kinds of pain – from joint pain to cancer pain. One finding is that CBD increases levels of glutamate and serotonin – both neurotransmitters that play a role in pain regulation. And CBD’s anti-inflammatory properties help by tackling the root cause of much chronic pain.
