Our Mission

Understanding the Genetics Behind Hallucinogen Use

HallucinoGenes is an international consortium that brings together research groups from around the world to conduct the first large-scale genome-wide association study (GWAS) meta-analysis of hallucinogen use. By pooling GWAS summary statistics across cohorts, we maximise statistical power to detect genetic variants associated with individual differences in hallucinogen use, without sharing any individual-level data.

A collaboration between Karolinska Institutet, Max Planck Institute for Empirical Aesthetics, and Amsterdam UMC.

How It Works

🧬

Run GWAS Locally

Each cohort runs a standardised GWAS on their own data using a shared analysis plan. Your data never leaves your hands.

📊

Share Summary Statistics

Only aggregate summary statistics are contributed. No individual-level data is transferred, ensuring full privacy protection.

🔬

Meta-Analyse Together

We combine results across all cohorts in a meta-analysis, increasing statistical power for variant discovery.

Get Involved

Join HallucinoGenes

We welcome all cohorts with genotype data and hallucinogen use phenotypes. Participation is straightforward, we provide a harmonized analysis plan.
