You CAN afford it
You were spending as much as $600/month on tobacco at 3 packs.
The amount your are saving now would pay for a lot of smoking cessation help. Many health insurances cover it, and there are free public programs for smoking cessation in many communities. Try 1-800-quit-now and see if you can find something in your area. You cannot afford not quitting. Combo of meds/support groups works better.
