Nearly 1 million people currently residing in the United States suffer from Parkinson’s disease. Though different medications have been used to help combat many of the debilitating symptoms, there is still no cure. For many living with some of the more advanced symptoms, surgery may even be necessary to help regulate specific regions of the brain.
CBD Effects and Cannabinoid Receptors
Through the years, numerous studies, experiments, and surveys have been conducted to introduce CBD alongside or in place of traditional medication and treatments for Parkinson's disease. Findings have revealed that CBD and other cannabinoids found in hemp, can potentially slow the progression of Parkinson’s disease. CBD has also recently been considered as a likely therapeutic option for Parkinson’s disease and other neurodegenerative disorders due to its neuroprotective properties  Research on Parkinson’s disease has explored the correlation between CBD and the endocannabinoid system (ECS). Evidence has shown that cannabinoids can interact with receptors CB1 and CB2 to modulate the release of dopamine 
Observations conclude that after introducing cannabinoids, Parkinson’s disease patients saw significant improvements in motor ability, impairments, tremors, rigidity, bradykinesia, sleep and pain . Even after just 1 week of treatment, overall well-being and improved quality of life were confirmed in patients that were administered a daily dose of CBD. Additionally, patients treated with CBD experienced a prompt and substantial reduction in the frequency of sleep disorder events . CBD has also demonstrated the ability to aide in patients experiencing psychosis due to Parkinson’s disease. After taking the cannabinoid for four weeks, CBD helped patients suffering from psychosis to experience a significant decrease in psychotic symptoms.
