Cannabidiol’s anti-anxiety (Zuardi et al., 1993, 2017; Crippa et al., 2009; Bergamaschi et al., 2011b) and antidepressant (Saito et al., 2010; Zanelati et al., 2010) potential seems to differ from other drugs with effects on the central nervous system, since we found no alterations in sleep architecture. Additionally, studies on the anxiolytic, antipsychotic and antiparkinson effects of CBD described no sedation or drowsiness side effects in their volunteers (Zuardi et al., 1993; Crippa et al., 2004; Fusar-Poli et al., 2009; Chagas et al., 2014a). These findings complement the literature on the few significant side effects resulting from the administration of CBD to humans in a wide range of doses, administered chronically or acutely (Bergamaschi et al., 2011b; Kerstin and Grotenhermen, 2017). It seems, therefore, that CBD has an adequate safety profile with good tolerability and does not affect psychomotricity or cognition (Hayakawa et al., 2007; Crippa et al., 2010; Bergamaschi et al., 2011b; Kerstin and Grotenhermen, 2017). This is particularly important in Parkinson’s disease, where motor and cognitive symptoms play a central role.
A wide variety of solvents can be used for extraction, such as chloroform, dichloromethane, petroleum ether, naphtha, benzene, butane, methanol, ethanol, isopropanol, and olive oil.[2][9] Currently, resinoids are often obtained by extraction with supercritical carbon dioxide. The alcohols extract undesirable water-soluble substances such as chlorophylls and sugars (which can be removed later by washing with water). Non-polar solvents such as benzene, chloroform and petroleum ether will not extract the water-soluble constituents of marijuana or hashish while still producing hash oil. In general, non-polar cannabis extracts taste much better than polar extracts. Alkali washing further improves the odor and taste.
Relevant studies are summarized in Table ​Table3.3. In a SPECT study of resting cerebral blood flow (rCBF) in normal subjects, CBD reduced rCBF in left medial temporal areas, including the amygdala and hippocampus, as well as the hypothalamus and left posterior cingulate gyrus, but increased rCBF in the left parahippocampal gyrus. These rCBF changes were not correlated with anxiolytic effects [102]. In a SPECT study, by the same authors, in patients with SAD, CBD reduced rCBF in overlapping, but distinct, limbic and paralimbic areas; again, with no correlations to anxiolytic effects [104].
The exclusion criteria for the trial were: (i) presence of organic brain syndromes; (ii) use of psychoactive drugs, including nicotine; (iii) presence of general medical conditions, assessed by the patient’s report during the interview and/or through physical examination; (iv) presence of psychiatric disorders (assessed with the SCID-IV); (v) pregnancy; (vi) previous history of any sleep disorder (based on the Pittsburgh Sleep Quality Index - PSQI); and (vii) recent changes in sleep time (variation of more than 2 h in the last 7 days, measured through the sleep log). Thus, the volunteers were all non-smokers and had not taken any medications for at least 3 months before the study. Moreover, none of them had used marijuana more than five times in their lives (no use in the last year) and none had ever used any other illegal drug. All subjects gave their written consent to participate after being fully informed about the research procedures, which were approved by the Hospital das Clínicas de Ribeirão Preto of University of São Paulo ethics committee (HCRP No. 17912/2013).
I'm reading this in disbelief. I feel kind of numb to be honest. I'm in collection for thousands because of all the medical treatments, surgeries, and travel. For nearly 8 years my wife has worked two and sometimes 3 jobs and every time I was well enough I worked two jobs trying to catch up and still we fell behind. Call it pride or stupidity, but we never asked for help of any kind. I take care of older neighbors and spend much of my free time working with disabled veterans. I feel like I've given everything I had to help others my whole life. Thank You one and all!

As the demand for CBD products has increased, some states have started to take action. Over the past two years, 17 states have passed “CBD-only” laws, assuring parents who purchase CBD oil to treat their sick children that they won’t face arrest or prosecution from state law enforcement for possessing what the federal government still considers a Schedule I narcotic.
"It's important to know that the research in this area is in its infancy, partly because we haven't really understood much about CBD until relatively recently," said Marcel Bonn-Miller, an adjunct assistant professor at the University of Pennsylvania Perelman School of Medicine. He pointed out that the classification of marijuana as a Schedule 1 drug by the DEA makes it difficult to get material to use in laboratory studies. Schedule 1 drugs have a high potential for abuse, according to the DEA, and are illegal under federal law.
