originally i found smoking cigarettes after joints gets your higher, 6 months ago i quit for 3 months (til i went out drinking, had one, had another one 2 days later, etc got back into it...) but found that after quitting for a couple weeks I got way more stoned off of joints- im assuming that some of the aveoli were starting to clear up in my lungs. on a side note ive played soccer/baseball for 13 years and have worked out 5x a week for the last few years..even smoking a pack a day and 2-8 grams of weed a week, I can still run 10k without stopping in decent time
one thing I would suggest is going to the gym, light cardio/workout then going down for a swim/steamroom..even if I havent had a smoke all day, when you come out of the steamroom you dont want a smoke, you feel cleansed, rejuvenated and clear minded; i would sometimes go hours after the gym without even thinking of smoking
replace smoking with the addiction of going to the gym-the first 5-10 times when you first start out might seem tedious and a hastle, but it becomes addictive and almost feels like you're wasting a day if you dont work out (plus you get nicely high after a good lung pump)
i need to quit soon, as I was typing i think i incorporated a little of what im going to try and do in the next 2 weeks when i start school..i have to for my health and wallet, where i live packs are $9-$13, so i spend on average $250 a month smokin
good luck on the battle bro, ill be joining you soon
