Smoking and HDL

I recently had a fasting blood test 17 days after I quit smoking.  I was shocked to see my HDL go from 19 to 26.  I have never had an HDL rating over 31 and my lowest ever was 15.  So that is quite a jump.  Did not smoking cause this jump? Does smoking effect trigs?  My trigs have been between 200 and 500 the last several years.  I currently take simvastatin 40mg, Niaspan 1500mg, aspirin, and fish oil.

All my test results were as follows:

HDL ...    26

LDL....    66

VLDL...   46

Trigs..    255

A1C...    5.4

TC...     143

I have a 32 BMI so I am overweight but my doctor believes my situation is mostly genetic. 

Thanks for any replies!!
