Hmm.. How to get by without smoking weed.. The answer is, Spice Diamond!
Or there's also Smoke, But I don't like the taste of that as much..
Have to say, if you really can't have the real deal, whether unable to attain or just plain not allowed, this stuff's great! And you can't get caught in a drug test because it's legal!
*This comes from experience of unatainability - I like using big words when I'm baked!
Wish you well if you chose to just stop altogether (or anyone quitting that reads this) and I remember getting into fitness (I chose cycling, fixie-fied as I find it interesting and not too strenuous on the knees like jogging!) since I had the energy to do stuff) and there's nothing stopping you! The hardest part is the initial cravings you have, like I'd nearly be punching walls (invested in a punch bag/stress toy) and once you get through that it's much easier, then you start to prefer not toking.. Then you'll find a way back to it years later when the job isn't an issue!
Best of luck!
