It really depends on how much you smoke, how often you smoke, and how long you have been smoking.
The less frequently you smoke, the shorter the period of time for your blood to be free from nicotine or signs of tobacco use.
However, there are some life insurance plans that do not require you to take any blood testing.
In fact, some insurance carriers offer you the option of buying up to $350,000 of life insurance with no blood tests required.
And, if you qualify, you may start your life insurance coverage the same day you apply online for your policy.
In addition, there's usually a 30 day money-back guarantee if you are not satisfied with your life insurance policy.
