Not likely. While HSV 1 can affect the genitals, what you described does not put you at risk of genital herpes. Smoking newspaper is not a treatment for cold sores. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines.
