Researchers from the UCL Clinical Psychopharmacology Unit are seeking daily cigarette smokers to take part in a study investigating the effects of Cannabidiol (CBD) on nicotine withdrawal.

The study involves one hour and a half session where you smoke as normal and two sessions of about four hours where you’ll be asked not to smoke for twelve hours before the sessions. You will be given either CBD or placebo across the two weeks. Note: these sessions have to take place on a weekday morning.

You will be reimbursed for your time and you will leave with the knowledge that you have contributed to the understanding of how we can modulate the endocannabinoid system to help cigarette smokers.

You must be London-based, in good physical and mental health, and able to pass a drug test on each day (including cannabis).

If you’re interested, email smokingstudy2017@gmail.com with the number of cigarettes you smoke a day.

This study is being carried out at University College London and has full ethical approval (ref: 7725-002). Your participation is completely confidential and you are free to withdraw at any time.
