The conclusion comes without further study. As an example, Professor Xia Zhang from the University of Saskatchewan discovered, which was further repeatedly verified, that marijuana causes neurogenesis [1]. This is interesting because other non marijuana related studies show that neurogenesis ends after puberty [2]. So, then, could the conclusion not be that the sudden growth of brain cells causes a sudden mismapping of information and memory within the brain causing slight issues with memory recall and retention until the brain is able to cope with and understand the neurogenesis?
