Low to moderate marijuana users actually show increased lung capacity compared to nonsmokers on two tests, known as FEV1 and FVC. FEV1 is the amount of air someone breathes out in the first second after taking the deepest possible breath; FVC is the total volume of air exhaled after the deepest inhalation. Both steadily improve in pure marijuana smokers. improve your lung capacity. Take a deep breath ! Getting high once a week on ganjika is good for you. Fast during the day , shiv pooja and mantra yoga in the evening followed by some bhang to break the fast. wake up early in the morning and do some surya namaskars ! health is wealth. never smoke it. eat it. like food. like bhang. smoking is bad for us. never mix with tobacco. shiva prasad has to pure. never adulterated. Live strong close to nature. Its mahadevas medicine. Use and dont abuse. The knowledge of our ancestors. LEGALIZE IT NOW ! Boom shankar !
