If you don't recocnize the socio-economic links to smoking, its you that needs to lay off the koolaid.
If your stating the root cause to asthma is poverty, how about we outlaw poverty. You know, that war on poverty that has been so successful over the last 40 years. Seems to work great.
Is that the road you want to travel, or would you prefer to outlaw smoking, just a symptom of the root cause?
