About 20% of North Americans smoke. How about about Tacoma owners?
Not to mention all the other reasons to quit, money spent on smoking obviously can't be spent on your Tacoma.
When you have any interest in quitting, ask your doctor (or pharmacist) about the options to help you quit. Ask especially about Varenicline [Chantix (USA), Champix (Canada)] - It is not for everyone, but it is the most successful way to go about it for most who have tried it (I don't work for Pfizer).
Every smoker should do the math every year. Eventually, you will figure out its time to quit. Its the toughest DIY that I know of. What are your reasons to quit? What are your reasons to continue smoking? Most people try at least four times before successful (I tried to set up the poll to allow multiple selections)
