STRAIN: This lifesaving strain has been in the news, a lot. It's the focus of a nationwide effort to legalize marijuana strains high in CBD. Charlotte's Web was named after Charlotte Figi, a young Colorado girl with severe epilepsy whose constant seizures were stopped by this strain. Her story brought public attention to a cause that has helped secure medical marijuana laws in more than a dozen states. Charlotte's Web won't get you high; its THC content is substantially less than 1%. But the CBD content can hit 17% or higher, making this one of the most powerful marijuana medications available.
