According to a study published in the journal Molecular Psychiatry, psychiatric disorders among smokers are on the rise. These disorders, such as bipolar disorder, antisocial personality disorder and attention-deficit hyperactivity disorder, were seen more among younger smokers.

Researchers studied data from more than 25,000 people born between 1940 and 1989. They found that although overall smoking rates are decreasing, the number of people becoming nicotine-dependent smokers is increasing. They also saw an increase in substance use disorders among all smokers over the years.

The dependent smokers born in the 1980s were most likely to be diagnosed with a psychiatric condition. This group of smokers is much smaller than the group of smokers born in the 1940s-1970s. Researchers state that all smokers, especially the younger smokers, would benefit from mental health and substance use disorder screenings. Early intervention and treatment makes all the difference.
