Im 37. I smoked pot for 19 years (never having to quit once), I stopped smoking on January 2012 for 3 years 9 months witch put me at September 2015.  I gained an astonishing 80lbs. while i quit smoking. I went from 175 to 255. Just 6 months ago (September 2015) I started smoking again and without changing a single thing in my lifestyle i have dropped 30lbs. I now weigh 225. I actually just weighed myself today after noticing that clothes were fitting me loose. I was and i am still in shock. Does anyone know how this is possible? The only thing i can think of on how i been loosing weight is by the pot because it starting dropping after i started smoking again. I haven't changed anything but that. Anyone?
