- There has been much speculation into the existence of a withdrawal syndrome involving cannabis much like withdrawal syndromes from opioids or alcohol. Our goal for this study was to estimate the prevalence of cannabis withdrawal syndrome (CWS) and to identify any risk factors for CWS.
- There has been a lot of research into cannabis withdrawal syndrome (CWS) in the past. A big part of this review involved understanding where the CWS field is in terms of the shared understanding on its epidemiology and physiology.
- To that end, we were not surprised to find that the prevalence of cannabis withdrawal syndrome was high. However, we found that some of the characteristics of CWS are consistent with other substance use disorders, which really serves to legitimize the decision to classify CWS and cannabis use disorders as psychiatric conditions.

MedicalResearch.com: Would you briefly explain what is meant by helmet-based ventilation? How does it work?
Response: For patients in respiratory failure, noninvasive positive pressure ventilation (NIPPV) is usually delivered through a nasal mask or facemask. Many patients develop pain, discomfort – even claustrophobia -- from using NIPPV systems. The transparent helmet was developed to improve the tolerance of noninvasive ventilation. It allows the patient to see, read, speak and drink without interrupting noninvasive positive-pressure ventilation (NPPV).
The helmet has a sealed connection and a soft collar that adheres to the neck which helps prevent the air leaks that are very common with nasal- or face masks. High positive end-expiratory pressure (PEEP) is vital in treating patients in respiratory failure and thanks to helmets “none to minimum air leak” system, PEEP can be set high (up to 25). NIPPV via a nasal- or full-face mask typically begins to show air leaks when the required pressure exceeds 15-20cm H2O.

MedicalResearch.com: What is the background for this study?
Response: In the past two months, the outbreak of Coronavirus Disease 2019 (COVID-19) has been spreading rapidly across the world. Science and technology is the most powerful weapon for human to fight against diseases, especially in such a pandemic setting. Seeking for effective antiviral medication is the most critical and urgent among the many scientific tasks in the pandemic.
At the most critical moment in the fight against COVID-19, Chinese clinical scientists have stepped forward under extremely difficult research conditions to carry out clinical trials in antiviral treatment including lopinavir–ritonavir and remdesivir, in a swift, decisive and effective manner. These trials have attracted worldwide attention.
Recently, the Lopinavir–ritonavir Trial for suppression of SARS-CoV-2 in China (LOTUS-China) has been completed, which, with great clinical significance, can provide strong evidence for the treatment of COVID-19 both in China and around the world.
