If it were up to me I'd be smoking 24/7 all year long, and I would never take breaks. But unfortunately, money and the fickle world of dealers often force me to stop. Like right now. I've been stone sober for several days, except earlier today I smoked a bowl of random crumbs I found on my desk and then scraped some resin out of the bottom of my bong with two paper clips taped together. Desperation is a bitch. It's okay though, I'm getting some weed tomorrow morning. I can't fucking wait.

The only real advantage I can see to taking breaks is the fact that it lowers your tolerance. But if you have enough weed that you don't have to take breaks, it doesn't matter how low your tolerance is.

I don't really see how taking a break would help your lungs if you smoke a lot of pot. It sounds rather like a fat person going on a diet for a couple weeks a year. It just isn't going to help a whole lot.
