"Side Effects" debuted at number 50 on the
Billboard Canada Country chart dated February 4, 2017 and has since earned Smith a record-extending fifteenth consecutive top 10 single. It reached the top position on the chart dated April 22, 2017, giving Smith a third number one. With this ascension, Smith becomes the first Canadian country artist to have at least three number ones at country radio since 1995, and the first to post back-to-back number ones since
Shania Twain last achieved the feat in 1998. Despite the song's airplay success, "Side Effects" became the first single of Smith's career to fail to enter the
Canadian Hot 100. Nonetheless, it has been certified Platinum by
Music Canada. ==Music video==
