  • There are many harmful effects of smoking
  • Smoking may also lead to a loss of hearing
  • For smokers, it can get difficult to listen to low-frequency sounds

Smokers beware. You may be at a higher risk of suffering hearing loss, as a new study suggests that smoking affects the ability to hear both high and low-frequency sounds.

“These results provide strong evidence to support that smoking is a causal factor for hearing loss and emphasise the need for tobacco control to prevent or delay the development of hearing loss,” said lead author Huanhuan Hu from the National Centre for Global Health and Medicine in Japan.

For the study, published in the journal Nicotine and Tobacco Research, researchers included 50,195 people, aged between 20 to 64 years and free of hearing loss.

The researchers analysed data from annual health checkups, which included audio testing performed by a technician and a health-related lifestyle questionnaire completed by each participant.

They examined the effects of smoking status (current, former and never smokers), the number of cigarettes smoked per day, and the duration of smoking cessation on the extent of hearing loss. The participants were followed up for a maximum of eight years.

Even after adjusting for factors including occupational noise exposure, researchers noted a 1.2 to 1.6 increased risk of hearing loss among current smokers compared with never smokers.

During follow-up, 3,532 individuals developed high-frequency hearing loss, and 1,575 developed low-frequency hearing loss. While the association between smoking and high-frequency hearing loss was stronger than that of low-frequency hearing loss, the risk of both high and low-frequency hearing loss increased with cigarette consumption, the researcher said.

The increased risk of hearing loss decreased within five years after quitting smoking, the researcher added. “With a large sample size, long follow-up period, and objective assessment of hearing loss, our study provides strong evidence that smoking is an independent risk factor of hearing loss,” Hu said.

Smoking marijuana may lead non-smokers to cigarettes

As cannabis use is much more common than cannabis use disorder, its potential impact on cigarette use in the general community may be greater than estimates based on studies of cannabis use disorder alone, the researchers said

If you only smoke marijuana there are higher chances that you may end up smoking cigarettes too, a new study suggests. According to the researchers, cannabis use is associated with an increased initiation of cigarette smoking among non-cigarette smokers.

While cigarette smoking has long been on the decline, marijuana use is on the rise and, disproportionately, marijuana users also smoke cigarettes, the researcher said.

“Understanding the potential links between cannabis use and cigarette initiation in youth is needed given that recent data suggest that cannabis use is more common among adolescents than cigarette use,” said co-author Renee Goodwin from the Mailman School of Public Health.

The analyses for the study, published in the Journal of Clinical Psychiatry, were based on data from the National Epidemiologic Survey on Alcohol and Related Conditions in 2001-2002 and 2004-2005, and responses from 34,639 individuals.

The results suggested that marijuana use — even in the absence of cannabis use disorder — is associated with increased odds of smoking onset, relapse, and persistence.

They also found adults who smoke cigarettes and use cannabis are less likely to quit smoking cigarettes than those who do not use cannabis. Former smokers who use cannabis are also more likely to relapse to cigarette smoking, the researcher said.

“Developing a better understanding of the relationship between marijuana use and cigarette use transitions is critical and timely as cigarette smoking remains the leading preventable cause of premature death and disease, and use of cannabis is on the rise in the US,” Goodwin said.
