Dear Editor
Regarding the manuscript written by Ghasemiesfe et al. “Association Between Marijuana Use and Risk of Cancer: A systematic review and meta-analysis” and published in the JAMA Network Open journal, we would like to make some comments.
1. First, the original idea was to submit this letter to the JAMA Network Open journal but, interestingly, they do not publish letters to the editor. At any rate, the article has some critical flaws regarding the supposed association that need to be carefully analyzed, as readers will see.
