Although putting analogues in Schedule 1 still theoretically allows them to be researched, the current situation regarding Schedule 1 licenses is such that this research will be severely hampered. The holding of Schedule 1 drugs is subject to a specific Home Office license that now costs about £5000 to obtain and then incurs significant time and other costs in relation to inspection . It also takes up to a year to get one. Currently we know of only 4 hospitals in the UK with one; neither Hammersmith Hospital or University College Hospital, two of the leading clinical research centres in the UK hold one. In contrast NHS hospital and university departments that conduct biomedical research which requires controlled drugs in Schedules 2-5 are exempt from the need to purchase a license to hold these. These hurdles induced by Schedule 1 status, though surmountable, effectively stifle research.
