I drink and smoke once a month. I always smoke around 10 cigs and drink around 2 liters of mixed alcohol. It feels great once in a while and i always get thoughts day after that i might get cataract and lung cancer but it always feels great and i don't wanna ruin my fun because i am afraid of what might happen, and people always tell me that chances of that things happening to me are so low and that i should not worry about it!? What do i do?
