Lethal doses are determined through toxicological studies that assess the effects of a substance on living organisms, often using animal models. Researchers typically calculate the median lethal dose (LD50), which is the dose at which 50% of the test population dies within a specified time frame. This involves administering various doses of the substance and observing the outcomes, allowing scientists to establish dose-response relationships. Regulatory agencies also consider factors such as exposure routes and individual variability when evaluating lethal doses for humans.
LSD is a very powerful drug, which is taken in micro-gram doses. Larger doses are lethal.
Yes, phencyclidine can be lethal if sufficient doses are taken. Even in sub-lethal doses, a person under the influence of PCP may accidentally harm or kill himself/herself or others .

The compound cyanide has no taste or smell, but it is lethal in small doses. It interferes with the body's ability to use oxygen, leading to cellular death and organ failure.
protein and a trace amount of arsenic that becomes lethal in high doses of ants
The lethal dose of mercury depends on the form of mercury and the method of exposure. Inorganic mercury can be lethal in doses as low as 1 gram, while organic mercury compounds like methylmercury are toxic in much smaller doses. Acute exposure to high levels of elemental mercury vapor can also be lethal.
The lethal word can be put into sentence as such. The bite of a snake is lethal and fatal.
I really don't know, why would you want to know though? I would suspect low doses over a long period of time or high doses at varying amount if time.

The lethal dose of Gravol (dimenhydrinate) can vary significantly depending on individual factors such as age, weight, overall health, and tolerance to the medication. In general, doses above 100 mg can lead to severe toxicity, while doses over 1,000 mg are considered potentially lethal. However, it's crucial to note that any overdose can be dangerous and medical assistance should be sought immediately in such cases. Always use medications as directed by a healthcare professional.
Donormyl, which contains the active ingredient doxylamine, is an antihistamine used as a sleep aid. The lethal dose can vary significantly between individuals due to factors like age, weight, and overall health. Generally, doses above 25-50 mg may cause severe side effects, and doses exceeding 500 mg can be potentially lethal. However, it's crucial to consult a medical professional or toxicologist for precise information and guidance regarding any substance.
