Cant say ive ever hear of them. A lil break now n then doesnt hurt.Not only only does it do your bank balance good, it clears your head and when you do pick up the bong/schpliff again it hits you like a noob! At the mo i havent toked for two weeks, cant remember the last time i did that as im a chronic smoker. I decided to take a break as i needed to get my head straight and sort out priorities. Once im there believe im jumping back on the band wagon!

Peace and hope to see you back on boards soon!
