psychosisA major study into the effects of cannabis on the human brain is at risk of being partially thwarted because too few black users have agreed to take part. White people have come forward in large numbers offering to get involved in King’s College London’s £2.5m study of how the drug may contribute to paranoia and psychosis in some users but not others. It is hoped the project will pave the way for wider medicinal use and make illegal recreational use safer. However attempts to recruit black and Asian people who smoke, vape or eat marijuana have been met with suspicion over how data about illegal drug use will be used and distrust of the establishment.
