Hemorrhagic cystitis or haemorrhagic cystitis is an inflammation of the bladder defined by lower urinary tract symptoms that include dysuria, hematuria, and hemorrhage. The disease can occur as a complication of cyclophosphamide, ifosfamide and radiation therapy. In addition to hemorrhagic cystitis, temporary hematuria can also be seen in bladder infection or in children as a result of viral infection. Causes
Causes of hemorrhagic cystitis include chemotherapy (e.g. cyclophosphamide, Ifosfamide), radiation, or  infection. Ifosfamide is the most common cause of hemorrhagic cystitis. Radiation-induced hemorrhagic cystitis develops in similar or smaller patient numbers when compared to cyclophosphamide-induced cases.Adenovirus (particularly serotypes 11 and 21 of subgroup B) is the most common cause of acute viral hemorrhagic cystitis in children, though it can result from BK virus as well. A chemical hemorrhagic cystitis can develop when vaginal products are inadvertently placed in the urethra. Gentian violet douching to treat candidiasis has resulted in hemorrhagic cystitis when the drug was misplaced in the urethra, but this hemorrhagic cystitis resolved spontaneously with cessation of treatment. Accidental urethral placement of contraceptive suppositories has also caused hemorrhagic cystitis in several patients. The bladder irritation was thought to be caused by the spermicidal detergent nonoxynol-9. In the acute setting, the bladder can be copiously irrigated with alkalinized normal saline to minimize bladder irritation.Although hemorrhagic cystitis post-transplantation/bone marrow transplantation is not technically infectious, a short discussion is in order for completeness.
However, there is also a response from the Ministry of Health of the Russian Federation indicating that CBD can be considered as an isomer of restricted THC. But the "isomer" argument is vague as   progesterone, which is freely sold in pharmacies, is also an isomer of THC, all three being C21H30O2. On February 17, 2020, the deputy of the Moscow City Duma Darya Besedina sent an official request to the Prime Minister of the Russian Federation Mikhail Mishustin with a request to eliminate that legal ambiguity by publishing official explanations and, if necessary, making required changes in the corresponding government decree. Sweden
Cannabidiol is classified as a medical product in Sweden. However, in July 2019, Supreme Court of Sweden ruled that CBD oil with any concentration of THC falls under the narcotic control laws. Switzerland
While THC remains illegal, cannabidiol is not subject to the Swiss Narcotic Acts because this substance does not produce a comparable psychoactive effect. Cannabis products containing less than 1% THC can be sold and purchased legally. Ukraine
On 7 April 2021 the Ukrainian government legalised use of isolated cannabidiol. Additionally, it approved Nabiximols, a cannabidiol-containing drug, for medical use.
