My IME always suggests both 菸 and 煙 for traditional 烟, which makes me think that they're interchangeable. Characters usually are not just simply exchangeable between themselves though.
What nuances exist between 菸 and 煙?

Conclusion:
Related to tobacco, use "菸"
Such as: cigarettes, tobacco, tobacco leaves, tobacco wine. "香菸、菸草、菸葉、菸酒"
Related to opium and drugs, or burning something without cigarette, use "煙"
Such as: smoking halls, smoke ghosts, smoke poisons, clouds. "煙館、煙鬼、煙毒、雲煙"
