I was wondering if its possible to catch anything from a disposable vape that i bought i have suspicion that it wasnt brand new and was resealed after someone using it. could i get something like hiv or hsv??

Not HIV or HSV, but any possible respiratory chemical or biological injury to the lungs that are limited in clearing chemical substances and will be affected in time from inhaling/ vaping/smoking.

You are risking lung injury from vaping. Stay away from it. HIV or HSV is not the risk you need to be concerned about. 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. Wish you good health!
