effects of lsd microdosing on humans, with a particular focus on mood, cognitive functions, and pain management. the first study, exploring the dose-response relationship in lsd-induced physiological and psychological effects, saw twenty-four healthy volunteers each receive single doses of 5, 10 and 20 micrograms of lsd, or a placebo. past projects and collaborations the beckley foundation/imperial college london psychedelic research programme, investigating the effects of psilocybin and other psychedelic drugs on cerebral blood flow, and linking this with cognitive effects (for example, improved episodic memory recall and increased vividness of subjective experience under the influence of psilocybin). the beckley foundation ethnobotanical research programme, investigating the effects and potential benefits of ayahuasca and dmt, including a study involving ketanserin on evaluating the effects of glutamate release by dmt, a study investigating the association between brain plasticity and ayahuasca, and a long-term study investigating the effect of ayahuasca on personal development and health. a beckley foundation/johns hopkins university collaboration investigating the potential use of psychedelic drugs to treat addiction. a pilot study using psilocybin to treat nicotine addiction produced promising results, leading to a multi-site clinical trial in the usa, funded by nih, in which the foundation is not involved. a beckley foundation/king's college london collaboration with dr paul morrison at the institute of psychiatry investigating the differing effects of delta-9-tetrahydrocannabinol (thc) and cannabidiol (cbd), two of the main cannabinoids found in cannabis that determine its subjective and cognitive effects. cannabidiol is showing promise in inhibiting the psychosis-like effects of thc, and indicating great therapeutic potential. a beckley foundation/university college london collaboration with professor valerie curran investigating medicinal uses of cannabis. a beckley/imperial psychedelic research programme collaborative study on psychedelic microdosing. recent scientific journal publications lebedev, alexander v.; lövdén, martin; rosenthal, gidon; feilding, amanda; nutt, david j.; carhart-harris, robin l.
