Toxicology?

The study of toxic or poisonous substances.

Toxin?

A poison or harmful substance.

toxin.

What percent of poisoning is by ingestion, approximately? What does that include?

80% Includes plants, contaminated food, and most drugs.

What is the go-to treatment for poisoning if permitted by local protocol?

activated charcoal.

What does alcohol do to the body that is dangerous?

It can depress the CNS and can cause respiratory depression.

Antidote that reverses the effects of opiate or opioid overdose?

Naloxone.

Which class of drugs stimulate the CNS, causing hypertension, tachycardia, seizures, and dilated pupils. What is the most popular drug in this class?

Sympathomimetics (mimic the sympathetic nervous system) . Cocaine.

Which medication, often taken in suicide attempts, can cause a person to become hot, dry, blind, red-faced, and mentally unbalanced.

Organophosphate poisoning?

Poisoning by organophosphates which include pesticides and insecticides, that function by inhibiting the enzyme acetylcholinesterase, disrupting the nervous system.
