Any confident claim that something causes specifically X% of asthma is BS. Asthma is a cluster of symptoms that researchers do not have a clear causal picture of. As NIH states, "The exact cause of asthma is unknown, and the causes may be different from person to person." https://t.co/bSKrNV1gWh — PolitiTweet.org
