humulene and Death--Sudden--Cardiac

The recreational use of illicit drugs remains an enormous and growing problem throughout the United States of America and around the world. Cocaine is most frequently thought of when considering the cardiovascular toxicity of illicit drugs. The association of cocaine use with sudden death due to myocardial ischaemia and infarction is well recognised, and this risk appears to be amplified by concomitant cigarette smoking and alcohol consumption. Like cocaine, amphetamine and its derivatives lead to indirect stimulation of the autonomic nervous system through the release of norepinephrine, dopamine, and serotonin in nerve terminals of the central and autonomic nervous systems. However, amphetamine lacks the ion channel-blocking properties of cocaine. Also similar to cocaine, coronary artery spasm may be induced in individuals with or without atherosclerotic disease and may lead to myocardial infarction. With the movement across the United States of America to legalise marijuana, or cannabis, for medicinal and recreational purposes, it is important to consider its potential deleterious effects. Marijuana has long been thought to have very few adverse effects with the exception of long-term dependence. There are, however, scattered reports of acute adverse events up to and including sudden death. These appear to be due to myocardial infarction. In conclusion, the incidence of sudden death associated with the use of these drugs varies from rare in the case of marijuana use to not infrequent with some drugs such as cocaine. It is important for care providers to recognise the potential for drug abuse when caring for a sudden cardiac arrest survivor.

We report a case of sudden death due to acute coronary syndrome (ACS) in a young cannabis user. A man in his late thirties died at home, and marijuana was found. The autopsy revealed severe occlusion by an atherosclerotic plaque in the left anterior descending artery. The histopathological examination revealed ischemic changes, likely caused by cannabis-induced sympathetic β-adrenergic stimulation. Both cannabinoid receptors (CB1 and CB2) were expressed in the atherosclerotic lesions. The CB2 expression was higher than CB1 expression in the atherosclerotic plaque, corresponding to macrophage infiltration. Since cannabis is regarded as a casual drug due to its lower levels of dependency, some individuals have supported legalized marijuana use. However, this case report will provide cautions on the casual use of cannabis.

The elevated risk of triggering a myocardial infarction by smoking cannabis is limited to the first 2 h after smoking.. To examine the possible role of cannabis in cardiac deaths. CASES AND RESULTS: From 3,193 coroners' cases over 2 years, there were 13 cases where the clinical information was compatible with a primary cardiac cause of death. An inquest was held in three cases. Myocardial infarction was the primary cause of death in 54%. Other causes were sudden adult death syndrome, sudden death in epilepsy, and poisoning by alcohol and diazepam. Cannabis was mentioned once only on a death certificate, but not as a cause of death. Blood delta9-tetrahydrocannabinol-carboxylic acid was recorded in one case and in no case was plasma tetrahydrocannabinol (THC) measured.. To attribute sudden cardiac death to cannabis, plasma THC should be measured in the toxicology screen in coroners' cases where urine cannabinoids are positive. A positive urine cannabinoids immunoassay alone is insufficient evidence in the linkage of acute cardiac death and cannabis.

A young adult male of about 25 years of age consumed a glass (about 300 ml) of Bhang on the holy occasion of ShivRatri. The deceased died within 24 hours of consuming the Bhang. The deceased had suffered from rheumatic heart disease with multiple valvular involvements. He had also undergone open-heart surgery in the past. Fatality due to Bhang is extremely rare and therefore the case is presented. An attempt is made to review the literature. Bhang is one of the Indian preparations of Indian hemp (Cannabis sativa). It is prepared by the wet grinding of the leaves of the plant. The bolus is then consumed in various ways. Water is used as a vehicle. In the present case a bolus of about 1 to 2 gm was mixed in a glass of water. ShivRatri is a Hindu festival. On this day prayers are offered to Lord Shiva, who is the god of all evils and poisons. Bhang is a special article, which is offered to Lord Shiva on this auspicious day. Then, the devotees consume it as the God. Gujrat is a dry state (possession, consumption, sale, etc. of alcohol, Bhang, opium and other psychotropic substance, etc. is governed by particular laws), but on the holy occasion of ShivRati, for a day, the law is relaxed for the use of Bhang. In most other parts of the country, particularly, in northern India, it is a common practice to consume various preparations of Indian hemp like Bhang, Charas, Ganja, sweetmeat, etc. The bolus mentioned above is probably the minimum single dose.
