WADA is tightening up what asthma drugs are allowed as described here:
"Tighter regulations on the use of asthma drugs are among changes to the World Anti-Doping Agency (WADA) List of Prohibited Substances and Methods for 2017.
Lisdexamfetamine, a drug used for treating attention deficit hyperactivity (ADHD) disorder and eating disorders, is also added to the banned stimulants list.
Opioid analgesic nicomorphine is a new addition to the list of banned narcotics.
The new list, published online before coming into force on January 1, makes clear that salbutomol, salmertor and formoterol are the only permitted "beta-2agonists" which can be used to treat asthma."
