Letter to the Editor: In reply to the correspondence of Johannes Rentzsch, Kristin Koller and Golo Kronenberg.

The article presents the authors' response to J. Rentzsch et al.'s commentary regarding their article "Cannabis Use and Transition to Psychosis in Individuals at Ultra-high Risk: Review and Meta-Analysis" which raised questions about the methodology and interpretation of findings. They agree that the relationship between cannabis use and psychosis needs further research and believe their meta-analysis contributed an important part in unravelling said relationship.
