Most people are under the influence of sedative-hypnotic drugs (such as alcohol or benzodiazepines) when they die by suicide, [136] with alcoholism present in between 15% and 61% of cases. [137] Countries that have higher rates of alcohol use and a greater density of bars generally also have higher rates of suicide. [ 138 ]
In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.
The median lethal dose of alcohol in test animals is a blood alcohol content of 0.45%. This is about six times the level of ordinary intoxication (0.08%), but vomiting or unconsciousness may occur much sooner in people who have a low tolerance for alcohol. [34]
The 2010 DrugScience study ranking various illegal and legal drugs based on statements by drug-harm experts. Alcohol was rated to be the 4th most harmful drug to users, the drug most harmful to others, and the most harmful drug overall. [74] Alcohol causes a plethora of detrimental effects in society. [25]

The government has acted swiftly to the recommendations made by the Advisory Council on the Misuse of Drugs (ACMD) and we fully support the banning of 15 new synthetic opioids as Class A drugs.
In toxicology, the lethal dose (LD) is an indication of the lethal toxicity of a given substance or type of radiation.Because resistance varies from one individual to another, the "lethal dose" represents a dose (usually recorded as dose per kilogram of subject body weight) at which a given percentage of subjects will die.
Outbreaks of methanol poisoning have occurred when methanol is used to adulterate moonshine. [12] Methanol has a high toxicity in humans. If as little as 10 mL of pure methanol is ingested, for example, it can break down into formic acid, which can cause permanent blindness by destruction of the optic nerve, and 30 mL is potentially fatal, [13] although the median lethal dose is typically 100 ...
