Hi, my husband is a smoker of 1 pack a day and he also smokes hash marijuana through a bong. He is having a hernia operation in three days and he is bipolar. He has been on abilify since 2005 but sometimes he goes off of it because he shakes so much, then when he smokes marijuana he feels great, clear thinking, and he stops shaking almost immediately. He wants to know can he smoke pot before the surgery?
