ADHD may CBD oil be an alternative?

The symptoms of ADHD are now relatively successfully treated with methylphenidate, does CBD oil from the THC free hemp variant offer an alternative? CBD oil is an oil made from hemp. However, not like hemp oil, from the seeds, but from a macerate or other extract from flower buds and their distillation. Important here is, the plant is free from the psychoactive substance THC, respectively, the content of THC is extremely low (0.2%). Thus, CBD oil does not have any effects of the drug cannabis or marijuana. For cannabidiol numerous therapeutic effects have been described, e.g.. REM sleep disturbance disorder (RBD). Its anti-oxidant effect as well as anti-inflammatory, antibacterial, antiepileptic, neuroprotective, anticonvulsiv, antiemetic, anxiolytic or antipsychotic effects give perspective for treating certain nerve infections, epilepsy, dizziness, vomiting, anxiety and schizophrenia as well as neurodegenerative or cancer diseases. For cannabis, however, there are 2 studies with interesting results that demonstrate the efficacy of cannabis (with THC) in adults with ADHD.
