Both CBD and THC are phytocannabinoids found in cannabis. However, the broader concept of cannabis should be distinguished from the narrower concept of marijuana, i.e. a variety of cannabis containing greater amounts of THC (tetrahydrocannabinol), which is an illegal substance not only in Poland, but also in many other places around the world. The main difference is that CBD - unlike THC - has no psychoactive properties, which results from the different reactions of these substances with the receptors of the human endocannabinoid system.
