Should I be taking a daily aspirin regimen?

I smoked for a little over 10 yrs. I have now quit and it's been almost 5 months now. I was overweight, but now I started exercising daily. I am 28 years old and am a white male. I take seroquel, cymbalta and clonazepam, a multi vitamin and magnesium supplement, i also take omeprazole daily for heartburn. I have gotten alot healthier since I quit smoking and drinking pop, and I have even been able to run again. Is the aspirin still necessary or should i quit taking it. It wasn;'t prescribed to me by a doctor. I used to drink alot of alcohol and did some experimental drug use mainly pot thanks
