"It's probably no surprise people would use person-to-person apps to try to sell illegal items because of the additional privacy the apps provide.
"In many regards people would feel, and probably are correct in feeling, that apps like Tinder are more private and anonymous than other social media services."
A Tinder spokesman said profiles promoting illegal drugs violated the app's terms of service.
"We have a system in place to remove these profiles from the app. If a user encounters a profile violating our terms, we encourage them to report it."
He said there did not appear to be any increase in this type of activity.
Last month, the Guardian reported that Tinder users were selling recreational drugs and prescription medication through the app.
