Benefits of quitting smoking pot?!

Benefits of quitting smoking pot?

I know about your lungs but will your memory improve? Concentration? Energy? Please only people that have experience. Also ive smoked for 15 years

Uh, can't believe some of the answers you got, people love to talk about stuff they know nothing about? Job? Try telling Mick Jagger he'll improve his financial situation when he quits smoking pot! Lol.
Your short memory will improve, not so sure about concentration. Not having an outlet is not exactly brilliant for concentration, then again it depends on what you are trying to concentrate on.
Taking in Photoshop lessons? You'll be more creative and less sterile if you have an occasional puff. Energy? That's down to tobacco and nicotine and what you eat and the exercize you take, a joint on saturday night won't affect any of it either way, if anything a good laugh does wonders for the soul and will help you concentrate on monday.
Unfortunately, giving up tobacco is impossibly difficult so for me it's no no on pot as well but it's tobacco's fault not pot's.
If you could keep it to the one joint on saturday nights it would be nothing but beneficial.
Then again if you are smoking tons of it every day, giving it up will give more get up ang go, but it all depends on how your life is structured.
Before you condemn pot, give up on alcohol and tobacco, those are the biggest enemies... and lack of exercize and junk food.
