CBD is not psychoactive, so you can't get stoned on it alone. Its chemical cousin, THC (tetrahydrocannabinol), is the only cannabinoid that causes a high. Marijuana-derived CBD oil comes from high-THC cannabis plants, which can contain varying amounts of THC. Hemp-derived CBD oil is extracted from low-THC cannabis plants; it's this nonintoxicating, hemp-derived CBD that is sold over the counter and added to so many products these days.
