Hello and welcome to Healthcare Magic. Thanks for your query.
Since you have had a serious lung problem recently and since you have bee told that you also have a geneitic problem in your lungs, the risk of harm due to smoking
marijuana (or anything else) is definitely many-fold greater that an 'average person'.
Ingesting such substances orally would also put you under significant risk. Alcohol or marijuana can put you at risk of an altered state of consciousness and hence put you at greater risk for aspitation. In whatever form they are taken, substances like marijuana have their own risks and adverse health consequences, and so, it is best to avoid them.
Wish you all the best.
Dr. Jonas Sundarakumar
