Step-by-step explanation:
Overdose: Overdose refers to taking an excessive amount of a drug or substance, resulting in harmful or toxic effects on the body. This can happen with both prescription and illegal drugs. Symptoms of an overdose can vary depending on the substance but may include sluggishness, incoordination, shallow breathing, and even coma or death.
Intoxication: Intoxication refers to the state of being under the influence of a drug or substance. It can occur when a person consumes alcohol or takes drugs in high doses. Alcohol intoxication, for example, can cause impaired coordination, slurred speech, and altered judgment.
Withdrawal: Withdrawal refers to the physical and psychological symptoms that occur when a person stops taking a drug or substance they have become dependent on. These symptoms are often the opposite of the drug's effects. For example, withdrawal from sedative drugs may cause restlessness and agitation. Some common withdrawal symptoms include anxiety, depression, and cravings.
