Покрай един assignment на една девойка от Department of Psychology компилация на малко инфо с извадки:
The neuropsychological correlates of cannabis use in schizophrenia (US National Institutes of Health)
Frequency and recency of cannabis use were also associated with better neuropsychological performance, predominantly in the domains of attention/processing speed and executive functions. In conclusion, cannabis use is associated with enhanced cognitive functioning in schizophrenia.

Cannabinoids: Between Neuroprotection and Neurotoxicity
Cannabinoids, such as the Δ9- tetrahydrocannabinol (THC), present in the cannabis plant, have been shown to protect the brain from various insults and to improve several neurodegenerative diseases.
Има известна двойственост, може да доведе и до някаква степен на невротоксичност. Уви, разясненията за това са в платената публикация
Non-acute (residual) neurocognitive effects of cannabis use: A meta-analytic study
total number of subjects to 1,188 (i.e., 704 cannabis users and 484 non-users). With the exception of both the learning and forgetting domains, effect size confidence intervals for the remaining 6 domains included zero, suggesting a lack of effect.
По-натам става дума за marginal ефект върху learning and forgetting при heavy user-ите.
Cannabinoids promote embryonic and adult hippocampus neurogenesis and produce anxiolytic- and antidepressant-like effects
Most drugs of abuse examined to date decrease adult hippocampal neurogenesis, but the effects of cannabis (marijuana or cannabinoids) on hippocampal neurogenesis remain unknown. This study aimed at investigating the potential regulatory capacity of the potent synthetic cannabinoid HU210 on hippocampal neurogenesis and its possible correlation with behavioral change
Chronic, but not acute, HU210 treatment promoted neurogenesis in the hippocampal dentate gyrus of adult rats and exerted anxiolytic- and antidepressant-like effects. X-irradiation of the hippocampus blocked both the neurogenic and behavioral effects of chronic HU210 treatment, suggesting that chronic HU210 treatment produces anxiolytic- and antidepressant-like effects likely via promotion of hippocampal neurogenesis
A pilot clinical study of Δ9-tetrahydrocannabinol in patients with recurrent glioblastoma multiforme
Тук е малко неясен ефектът, но като цяло е положителен, като пациентите са подбрани с необратимо смъртна прогноза.
Delta9-Tetrahydrocannabinol inhibits epithelial growth factor-induced lung cancer cell migration in vitro as well as its growth and metastasis in vivo.
THC inhibited EGF-induced growth, chemotaxis and chemoinvasion
there was significant inhibition of the subcutaneous tumor growth and lung metastasis of A549 cells in THC-treated animals as compared to vehicle-treated controls.
