Disease secondary to heroin abuse constitutes a rarity in Spain. While there had been no previous cases in earlier years four young heroin addicts were admitted to the Hospital "1st de Octubre" for severe medical complications of their addiction within the last twelve months. Two patients were admitted in deep coma due to drug overdose, being cardiac arrhythmias and pulmonary edema the main associated complications. Cardiac rhythm disturbances are due to a heightened vagal tone, either secondary to inhibition of acetylcholine hydrolysis or to hypoxia, hypercapnia, and acidosis, factors that diminish cholinesterase activity and act synergistically to increase vagal tone. Pulmonary edema secondary to heroin overdose is non-cardiogenic and probably due to hypoxia added to the local action of heroin on the alveolocapillary membrane. The goal of therapy in such cases is to obtain an appropriate alveolar ventilation, the use of continuous positive pressure ventilation being required when there is pulmonary edema. The third patient had staphylococcal pneumonia with multiple abscess formation secondary to venous septic embolization originated peripherally where the drug was injected. Finally, the fourth patient was admitted because of a clinical and biochemical picture of HBsAg negative acute viral hepatitis, having suffered a similar clinical picture three years previously.

Various drugs are associated with adverse respiratory disorders (ARDs) ranging in severity from mild, moderate to severe and even fatal. Cardioselective and nonselective beta-blockers, calcium antagonists and dipyridamole can induce asthma. ACE inhibitors are mainly associated with cough. Amiodarone is related to a form of interstitial pneumonitis (IP) which can be fatal, tocainidine and flecainidine to a form of IP, and hydrochlorothiazide to a form of IP and pulmonary oedema. Antiasthmatic drugs can be associated with a paradoxical bronchospasm, while leukotriene antagonists are linked to the development of Churg-Strauss syndrome. Nonsteroidal anti-inflammatory drugs including aspirin (acetylsalicylic acid) may induce asthma. Gold is mainly related to IP, penicillamine to IP, systemic lupus erythematosus, bronchiolitis obliterans, and Goodpasture's syndrome. Acute respiratory reactions to nitrofurantoin include dyspnoea, cough, IP, and pleural effusion while IP and fibrosis are common in chronic reactions. Other antibacterials mainly evoke pneumonitis, pulmonary infiltrates and eosinophilia, and bronchiolitis obliterans. ARDs are similar for most categories of cytotoxic agents, with chronic pneumonitis and fibrosis being the most common. Noncardiogenic pulmonary oedema occurs as the most common respiratory complication in opioid agonist addiction. Psychotropic drugs such as phenothiazides, butyrophenones and tricyclic antidepressants can also induce pulmonary oedema. Oral contraceptives may produce asthma exacerbation, while long term use and/or high doses of postmenopausal hormone replacement therapy increase the risk of asthma. Bromocriptine is mainly associated with pleural effusion, while methysergide is usually associated with pleural effusion and fibrosis. Some anorectic agents have been linked to the development of primary pulmonary hypertension. The possibility of the occurrence of ARDs should be taken into account in each individual patient. Although in most cases the adverse effects are unpredictable, they can be reduced to a minimum or prevented if some drugs are avoided or stopped in time.

Ephedra is an amphetamine-like compound with a potent sympathomimetic effect. Ephedrine, its active component, is widely used for weight loss, to enhance athletic performance or as component of some drugs. Its cardiovascular effects include tachycardia, increased inotropy, arterial vasoconstriction and hypertension, and these are the effects for which it is used therapeutically. However, it can also cause adverse effects, such as neuropathy, myopathy, psychosis, addiction, stroke, insomnia, myocarditis, arrhythmias, myocardial infarction or sudden death. We present the case of a patient, with pre-existing psychiatric conditions, who developed congestive heart failure and pulmonary oedema in the context of severe biventricular dysfunction and myocardial necrosis secondary to longstanding ephedrine abuse. Secondary causes of dilated myocardiopathy such as alcohol abuse, autoimmunity, hemochromatosis, thyroid alterations, viral or bacterial myocarditis and coronary heart disease, were ruled out. Five years after total cessation of use of the drug containing ephedrine, the patient is symptom-free, with partial recovery of left ventricular ejection fraction.

More than 750,000 persons in the United States inject opioids, methamphetamine, cocaine, or ketamine, and that number is increasing because of the current opioid epidemic. Persons who inject drugs (PWID) are at higher risk of infectious and noninfectious skin, pulmonary, cardiac, neurologic, and other causes of morbidity and mortality. Nonjudgmental inquiries about current drug use can uncover information about readiness for addiction treatment and identify modifiable risk factors for complications of injection drug use. All PWID should be screened for human immunodeficiency virus infection, latent tuberculosis, and hepatitis B and C, and receive vaccinations for hepatitis A and B, tetanus, and pneumonia if indicated. Pre-exposure prophylaxis for human immunodeficiency virus infection should also be offered. Naloxone should be prescribed to those at risk of opioid overdose. Skin and soft tissue infections are the most common medical complication in PWID and the top reason for hospitalization in these patients. Signs of systemic infection require hospitalization, blood cultures, and a comprehensive history and physical examination to determine the source of infection. PWID have a higher incidence of community-acquired pneumonia and are at risk of other pulmonary complications, including opioid-associated pulmonary edema, asthma, and foreign body granulomatosis. Infectious endocarditis is the most common cardiac complication associated with injection drug use and more often involves the right-sided heart valves, which may not present with heart murmurs or peripheral signs and symptoms, in PWID. Injections increase the risk of osteomyelitis, as well as subdural and epidural abscesses.
