Why do clinical trials take so long?

The clinical trial process is long – and it’s set up that way so that by the time drugs reach the public, they have been thoroughly evaluated. But the length of the process is one reason why it’s so important for volunteers to take part. Without enough volunteers, up to 80% of clinical trials are delayed.
