Yleiskatsaus tutkimukseen

Me Bedrocanilla pyrimme rakentamaan sillan kannabista tarvitsevien potilaiden ja modernin lääketieteen laatuvaatimusten välille. Se on tutkimustoimintamme painopiste. Me rakennamme vahvoja akateemisia ja yksityisiä tutkimuskumppanuuksia ja teemme itsenäistä tutkimustyötä. Loppujen lopuksi me jaamme muille sen, mitä olemme oppineet.
