for me it can go both ways.
I can get very emotional awter some weed, but i actually have never kicked opiates without them.
Last time i WD, i ate some sleeping pills,an odd combo and smoked some weed.
MAN, i was tripping my head of.
Still serious rls so i went for walks in the middle of the night, and couldn't freakin recognize my own neighbourhood.
First time i went into rehab, i would detox for 3 weeks.
I fiigured it'd be no fun, after misusing and IVing Herion for 10 years, so i hid a stash of exellent hashish inside some musiccassettes.
Good old days
They passed the security, and the first night i freaked so bad, that i thought, f8ckthis, i'm having a joint,they're gonna kick me out of here and i'll be dopefree.
Or well,actually right the opposite, but....outside and on a roll.
I sat in the coffeeroom that night and rolled me a big splif, filled with the finest Hash i ever found until then.
Seeing weed is legalized in my country, that says a lot.

I smoked until the room was blue with the smell of hashish, up until the hallways.
BUT NOONE came to kick me out.NOONE checked at night.
I rolled another one and got so stoned , it became a very memorable moment, hellish,still...i got through allthough i became ar less carefull in my use of hashish, no one noticed.Very strange rehab centre, i can tell you.
Just remember that weed can slow down time or speed it up in a strange way.
ihope you get the results you hope for,i'm in wd now,and the joints kindaput my mind on other things.
