For me It still comes back to the lack of CRM... cockpit gradient etc. FOs should have the balls to stand up to these captains and Captains should be nothing other than plain bloody CIVIL! Chatting to smoker friends, even they say smoke in confined areas is hard to swallow

Eyes affected, Sinus problems etc. All this from people who are used to the Drug... I can only sympathise with these FOs. But in all honesty... Brutally honest here... Stand up to them, winging on this page is not where your fight should start. If you're not head strong enough to simply ask someone to refrain from smoking, which is polite and sensible, Then go fly single pilot ops...
Power went to my head then...

Maybe just a chat on the ground would suffice?
Good Luck with it all...
Ps I am on your side honest!!
