[2][3][4][5] Tove Lo said she and the group "had a few sessions and tried to find more days together, but we're never in the same place long enough to actually make it work", so she sent Diplo her vocals for a song, which he liked and put to a track.

[6] Billboard's Marina Pedrosa called the song a "tropical dance anthem" as well as an "electropop tune" containing a "sultry beat with a dash of reggaeton" that Lo's "angelic voice" sings lyrics like "I got the keys to heaven now/Babes all around and they got my mind spinning" over.

[2] Mike Wass of Idolator positively contrasted the song with Lo's solo material, noting that on "Blow That Smoke" it sounds like she is having fun.

[3] Writing for Dancing Astronaut, Chris Stack named it a continuation of Major Lazer's recent output "celebrating their Afrobeat roots" and also judged it had a "sultry island beat".

[4] Patrick Doyle of Rolling Stone felt that the song had "Afropop roots" as well as being a "bouncey stomper with a West African guitar riff and heavy groove".
