I don't think someone should be restricted from receiving organs because they smoked, drank whatever. Personally, my dad is a heavy smoker who has tried numerous times to quit and is probably killing his lungs. However, he also (ironically) works for a hospital and helps in saving peoples' lives, he is a loving father and husband, and does volunteer work around the community. Therefore, even though he may be responsible for the demise of his own lungs, does that mean he is not deserving to get a second chance. By denying him organs you are essentially letting a man die who gives so much back to the community, all because of a decision he made back in high school.
Also if we are talking about deserving people of organs should we also consider the obese? Surely poor dietary and exercise choices are the result of a number of obese people with weak hearts and such. What about athletes who kill their body with steroids? Or what if the patients disease is the result of the mother drinking or smoking while pregnant? Ultimately everyone makes mistakes and has vices they deal with. However, usually these people also do good and are beneficial to society in some way. If you wanted to limit your organs to so called deserving people, you may find that there a few people eligible for your organs.
