well the pros are obvious but there are some cons that i have come to realize especially lately.
I do feel that smoking makes me a less energetic person and when i smoke i would definetly rather just chill than try and get things done.
Also it seems to slightly change my perception on what is said and what is really meant, this seems to cause so problems but other than that, and that its illegal where im at, there isnt much "wrong" with it.
