CANTRIPS is an online study that investigates the relationship between unusual perceptual experiences, cannabis use and cognitive functioning. 

After completion of the online study you will be asked if you would like to take part in optional reimbursed follow-up interviews and cognitive testing online or at the Institute of Psychiatry, Psychology and Neurocience, King's College London. 

We are looking for individuals of any gender aged 16 - 35. English language fluency is required. We are especially looking for individuals that have unusual perceptual experiences or thoughts and may or may not use cannabis. However, everyone else that meets the age and english eligibility criteria is also welcome to take part.

First of all, with your participation, you make an important contribution to science. 

Second, during the study, you will get immediate feedback about your performance in our tasks.

Third, you get the chance to win a £100 prize for completing the whole online study. 

 Fourth,  you get reimbursed for your time with a £20 voucher for completing the whole study including the follow-up interview.
