Am I eligible to take part?

I drink alcohol. Can I take part?

You can take part in most of our medical trials if your weekly alcohol intake is less than 21 units if you’re a man and 14 units if you’re a woman. However, if you drink too much, you may not pass the screening blood tests. We recommend that you try to drink less, don’t drink too much, it isn’t good for you!!

I’m a smoker. Can I take part?

Eligibility criteria depend on the trial. We often have trials for just non-smokers, but sometimes for smokers and non-smokers. Trials for smokers have restrictions such as ‘only up to 10 cigarettes per day’ and you cannot smoke while you’re at the unit.

Why is alcohol and caffeine restricted?

Caffeine, alcohol and substances in grapefruits may affect your body. For example, alcohol, like medicines, is broken down in the liver, and can affect blood tests. If you drink alcohol while you’re on a medical trial, we won’t know whether it’s alcohol or medicine affecting your results. So, you need to follow the study restrictions.
