Substance Intoxication

Intoxication is a state of mental and physical impairment following the consumption of a psychoactive substance. The length of each intoxication period depends on a person’s age, medical history, substance tolerance, and amount taken. Substances that can cause intoxication include alcohol, marijuana, stimulants, opioids, and inhalants. Generally, substances taken in moderation will lead to a temporary period of intoxication that results in little to no negative side effects down the line.

In some cases, overconsumption of substances like alcohol can lead to moderate or severe intoxication. In the case of alcohol, severe intoxication lasts longer, is more intense, and results in more fatal accidents than mild or moderate intoxication. For substances like opioids, however, severe intoxication can result in an opioid overdose, a condition with a much higher mortality rate than alcohol poisoning. While all forms of intoxication have their risks, it is especially important to be cognizant of the dangers of opioid overdoses

Substance Use Disorder

Occur when the recurrent use of alcohol and/or drugs causes clinically significant impairment, including health problems, disability, and failure to meet major responsibilities at work, school, or home.

Suicidal Ideation

Suicidal ideation, often referred to as suicidal thoughts, are recurrent thoughts of death or suicide. These thoughts can vary widely in intensity, fluctuate with time, and tend to worsen in stressful situations. People with depression and other depressive mental disorders are at a higher risk for suicidal ideation. It is also more common in people below the age of 18, with an estimated 18% of minors in the U.S. experiencing suicidal ideation at some point in their lives. 

Even though suicidal ideation is not a definitive measure of someone’s likelihood to attempt suicide, it is important to take any thoughts of suicide seriously. It is impossible to determine if someone’s thoughts of suicide will result in an attempt, so it is best to err on the side of caution and seek professional help as early as possible. Treatment for suicidal ideation includes therapy and potentially medication, only if prescribed by your doctor as self-medication can make thoughts of suicide worse. If you (or a loved one) live in the U.S. and experience suicidal ideation, you can call 988 to get over the phone support from professionals through the national Suicide and Crisis Lifeline.
