my friend has 1:1 CBD:THC pills that r 2.5 mg each they r from a dispensary. will they work 2 help her sleep?

"This is for my mom who doesn't smoke or tried marijuana in her life. "

I have difficulty with anything with THC when it comes to sleeping. I prefer just CBD oil for relaxing me at night. My experience is non smokers can sometimes get increased anxiety if they aren't accustomed to THC. Everybody is different but my sense is straight hemp oil might be a better place to start. It's helped me with chronic insomnia.
