Marijuana-Based Drug Helps Kids With Rare Forms Of Epilepsy In Studies, GW Pharma Reveals

An oil derived from marijuana plants proved effective in a rare form of epilepsy that afflicts 30,000 Americans, its maker said this morning.

GW Pharmaceuticals, a London-based company, is developing a drug called Epidiolex, a pharmaceutical-grade form of cannabidiol (CBD), an oil found in the marijuana plant. GW says Epidiolex, an oil that is taken orally, contains only trace amounts of tetrahydrocannabinol (THC), the compound that makes pot smokers high. GW grows marijuana plants that have been bred to produce lots of CBD and very little THC in greenhouses in England, and then purifies its oil using a manufacturing process.
