Thanks for your question on Healthcare Magic. I can understand your concern. Yes, you should avoid all forms of smoking including cigarette, hukka, Marijuana etc. Also avoid second hand smoking (passive smoking). You already had pneumothorax twice, so your lungs are already weak and prone for further damage. Any form of smoke will damage your lungs further. So if you start smoking or having exposure two second hand smoke then chances of recurrence of pneumothorax, lung infection, bronchitis etc are more. So for your betterment, as a doctor, I advice you to avoid all forms of smoke. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
