Cannabis use induces a variety of acute psychological and physiological effects that vary in intensity and duration according to the dose, the route of administration, and the degree of tolerance in the user. Acute psychological effects include euphoria (“high”), relaxation, and sedation (usually desired by persons who use cannabis recreationally), increased appetite (“munchies”) and impaired short-term memory, concentration, and psychomotor coordination. Some people experience increased anxiety, panic attacks, or paranoia, especially at higher doses. Psychotic symptoms, such as perceptual alterations, hallucinations, and delusions, are less common. Acute physical effects include impaired motor coordination, slurred speech, dry mouth, conjunctival injection (“red eye”), tachycardia, orthostatic hypotension, and horizontal nystagmus. Smoked cannabis induces cough, wheezing, and dyspnea; increases sputum production; and exacerbates asthma.

DSM-5 Criteria for Tobacco Use Disorder
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), provides criteria for the diagnosis of tobacco use disorder, which falls under the category of substance-related and addictive disorders.
DSM-5 Diagnostic Criteria for Opioid Use Disorder
Opioid analgesics (termed opioids in this report) are a class of drugs commonly prescribed to treat moderate to severe pain. Opioids include drugs available by prescription such as oxycodone, hydrocodone, codeine, morphine, and fentanyl. Opioids also include illicit substances such as heroin and fentanyl. Although often prescribed to control pain, opioids may also produce feelings of euphoria and sedation which may lead to misuse of opioids resulting in opioid use disorder.
Guidelines for the Use of Erythropoietic Proteins in Anaemic Patients with Cancer
Anaemia is a frequent finding in cancer patients and should be carefully assessed. Additional causes of anaemia such as iron deficiency, bleeding, nutritional defects or haemolysis should be corrected prior to erythropoietic protein therapy. The following recommendations are related to adult cancer patients with solid tumours or haematological malignancies:

Recommendations for the Use of Ambulatory Blood-Pressure Monitoring
In addition to the prediction of cardiovascular risk, ambulatory blood-pressure monitoring, when used in conjunction with clinic blood-pressure assessments, is of potential value in a variety of other clinical conditions. Some of these conditions are:
