Spontaneous pneumothorax (that is, not due to trauma) is not all that uncommon, especially if someone in your family has had it happen to them. There is a genetic link and the chances are higher if you also suffered from asthma at any time in your life. People who get spontaneous pneumothorax are more likely to suffer from emphysema later on, so you shouldn't be smoking anyway. The most common genetic disease responsible for pneumothorax is alpha-1 anti-trypsin deficiency, but if you have the full on disorder you would have had other signs already. If you are only a partial carrier, you may lack some A1AT in the lungs but not to levels that would cause obvious symptoms yet. (I know all this because I'm a partial carrier.)
The chemical byproducts of smoking don't affect just the lungs but the plural cavity around the lungs. If it weakens or breaks, you get a pneumothorax. If you're prone to this happening you should really cut back on your smoking or don't smoke at all, especially if A1T1 deficiency is suspected.
Deep breathing that involves raising the shoulders and really expanding the rib-cage (like when you deeply inhale pot), and holding your breath, would be more likely to puncture the plural wall if it's already weakened. Besides, this deep breathing is not necessary to get the full effect of pot.
