Can smoking effect erection and hardness of an erection?

Yes, smoking does effect the ability to get an erection. Smoking (nicotine) causes

blood vessels and in the body to constrict. This reduces blood flow to extremities

like fingers and toes and yes, no matter what size you are, your body considers

your penis an extremity. So unllike Viagra and the like which open up the bloos vessels

to make you a happy camper, smoking closes them down. Heavy smokers have more

of a problem and the older the smoker the lesser the ride. Combine this with other

maladies such as high blood pressure, anxiety, depression, prostate problems

and any other number of problems and well...let's just say you're gonna be headin'

down the runway but you won't be taking off.
