Yes, taking a tolerance break from weed makes sense for these reasons;
1) Resumes restorative REM sleep which will make you clearer when you wake. You will experience and remember your dreams more clearly.
2) Decreases the overall 'oh I must get high to enjoy this activity' feeling.
3) From my experience long time smokers experience irritation in the mouth, throat and neck areas. A break period of about 1-2 weeks clears this up.
Not sure if the phrase,' we're just a habit like saccarine' or what were once vices are now habits; Paul Simon and Steeley Dan respectively....Tolerance breaks help you enjoy weed time more and it gives you some time. Even Neil Young quit smoking weed to write his autobiography.
