I think taking a break will lower your tolerance, but if it's something you've done a bit, it's like riding a bike. I remember getting stoned early on and it was all such a new feeling. Now even with a break or with really killer bud, I recognize the feeling and I'm used to getting shit done in it.

1st few times getting high = floored to the couch starving, giggling, not able to drive a golf cart very well much less a car.

now = take a month break and burn one down and I'm good to go to work.
