Hello and welcome to Healthcare Magic. Thanks for your query.
can result in foul odours from the mouth, it is not possible for smoke to come out through the pores of your skin after smoking. A perception of foul odour from the body can be due to a variety of causes - both medical as well as psychological. Often a psychological problem called "olfactory reference syndrome" could be the underlying cause when a person becomes excessively preoccupied and believes that he / she is smelling bad to others.
Since you seem to be quite distressed about this problem, and are having problems at your workplace also, I would suggest that you see a doctor for a detailed evaluation and further management.
Wish you all the best.
Dr. Jonas Sundarakumar
