Bad news for coffee-drinking smokers: the toxic chemicals in tobacco make a person unable to fully taste the bitterness of coffee.
The information appeared in the journal Chemosensory Perception.
The researchers pinpointed the chemicals in tobacco, which are proven to make a smoker lose his or her sense of taste over time. The chemicals also create structural changes of the tongue.
The long-term effects of smoking on taste buds are still not fully known, however. It could be possible for someone to regain his or her sense of taste after giving up smoking for a long period of time.
