Hi, I Had Vats Surgery For A 40% Collapsed Lung

Hi, i had vats surgery for a 40% collapsed lung about march 28th, i use to be a heavy cigarette smoker and a all day pot smoker.... since the surgery i stopped smoking cigs and weed all together. Its been maybe 20 days since the surgery.. im curious if i can still smoke a little pot here and there with out much consiquence. I dont want to be an all day,smoker again but maybe a hit or 2 at night.
