In January 2015
Norwegian Ski Federation "was informed that Johnsrud Sundby had crossed the legal limit, the so called 'decision limit', in regard to the use of" [salbutamol trademarked as]
Ventolin; the federation should have acted then, is the opinion of Fredrik Aukland,
NRK's expert on crosscountry skiing.

On 20 July 2016 Johnsrud Sundby was banned from competition for two months by the
Court of Arbitration for Sport (CAS) for an
anti-doping rule violation.
[6] His use of
asthma medication
salbutamol, resulted in test levels of urine sample, exceeding the very high 1000 ng/ml limits set in the anti-doping rules by 35% for two samples collected in competition, on 13 December 2014 and 8 January 2015.
[6] The facts of the case were undisputed and the decision focused on the meaning of the term "inhaled salbutamol", specifically whether the 1600 μg per day limit referred to the "labelled dose" or the "delivered dose". The CAS panel decided that the intended meaning was the former, but criticised the drafting of the rule. For this and other reasons, including that Johnsrud Sundby declared salbutamol at the time of the test, the panel found his degree of fault light and opted for a short sanction.
[6] As the tests were taken in competition, the two results were automatically stripped. This led to Johnsrud Sundby losing the
2015 Tour de Ski title and the overall world cup title for the
2014–15 season. Apart from the subsequent stages of the 2015 Tour de Ski, no other results were affected. His short suspension took place in summer months outside the competitive skiing season.

At a 21 October 2016 national convention of
Norwegian Ski Federation (NSF), some of the local representatives had a critical view on the federation having compensated Johnsrud Sundby for his loss of prize money due to his breaking the rules against doping
