What to know about phantom smells (phantosmia)

Phantosmia is the medical word used by doctors when a person smells something that is not actually there.

Phantosmia is also called a phantom smell or an olfactory hallucination. The smells vary from person to person but are usually unpleasant, such as burnt toast, metallic, or chemical smells.

Problems with the nose, such as sinusitis, or conditions of the nervous system or brain, including migraine, stroke, or schizophrenia can cause phantosmia.

In this article, we look at the causes and symptoms of phantosmia, when to see a doctor, and how to differentiate phantosmia from related conditions, such as parosmia.

Teen marijuana use may lead to bipolar symptoms later on

It’s a well-known fact that many young people use cannabis, and studies have pointed to a link between the drug and psychiatric conditions such as schizophrenia. However, the links between cannabis use and the development of bipolar symptoms over time have been insufficiently studied — until now.

A new study fills this research gap by examining how cannabis use among teenagers is linked with hypomania in early adulthood.

The research was led by Dr. Steven Marwaha, a clinical academic psychiatrist from the University of Warwick in the United Kingdom, and the findings were published in the journal Schizophrenia Bulletin.

Quantum Units Education: New CEU Courses

Women Who Inject Drugs: Risks, Experiences, and Needs

Women who inject drugs have substantially different needs and face higher risks of disease and violence than do men who inject drugs.  This CE course seeks to illuminate the many reasons a focus on drug-injecting women is important, including their significantly higher mortality rates, increased likelihood of facing injecting-related problems, faster progression from first use to dependence, higher rates of HIV, increased risky injection and/or sexual risk behaviors.

Prevention of Youth Violence and Risk Associated Behaviors

Youth violence is a significant public health problem that affects thousands of young people each day, and in turn, their families, schools, and communities.  This CEU course includes programs, practices, and policies with evidence of impact on youth violence victimization, perpetration, and risk or protective factors for youth violence.

Pharmacological Management of Schizophrenia

This CEU course provides recommendations for treatment of inmates in federal facilities who are diagnosed with chronic psychotic disorders.

Child Welfare and Human Trafficking

Often, the lack of stability in a child’s living situation, physical distance from friends and family, and emotional vulnerability put them at risk for traffickers who are actively seeking children and teens to exploit.  This CEU course provides a broad overview of the crossover between the child welfare field and the work currently being done to prevent and respond to human trafficking of children and youth in the United States.
