Ginak. It is my understanding that the current issues with vaping thc have to do with the oils that are created as part of the inhalation/deliveryprocess. Lungs, especially those with compromising conditions such as Mac or ntm’s, should not be exposed to substances that would inhibit oxygen exchange. I would check with your pulmonologist and follow recommendations . I don’t believe much if any research has been done regarding cannabis or thc vaping and more and more reports of lung damage are surfacing each day. I would definately proceed with caution and check with my pulmonologist. This is just my opinion.
