There is quite a plethora of this information and to give you everything you want, you'd need to pay me.
Maybe a better way is to write something that we could then edit for accuracy or include known evidence supporting or contradicting what you're saying. This also targets the information to that you require. Otherwise I could give you information on the interaction between endogenous corticosteroid function and CB1 receptors and the implications this could have on animal models of schizophrenia, or, I could give you qualitative 'research' on a user's experience while under the influence of cannabis in positive and negative environments, or, interaction effects between cannabis and commonly used drugs of abuse, or, the pharmacokinetic profile of THC and its metabolites, or, .....

Cannabis use and psychiatric and cogitive disorders: the chicken or the egg?

PURPOSE OF REVIEW: Cannabis is the world's most commonly used illicit drug. In this review, we consider the recent literature on the effects of cannabis on mental health and on cognition. RECENT FINDINGS: Cannabis use in adolescence increases the risk of later schizophrenia-like psychoses, especially in genetically vulnerable individuals. Not surprisingly, patients already suffering from psychosis who use cannabis have a worse outcome than those who do not. These effects of cannabis may be consequent on its impact on the dopamine system. There is less evidence of cannabis playing an aetiological role in other mental disorders including depression, but there have been far fewer studies. Heavy cannabis use has also been shown to affect memory and learning performance, both in healthy individuals and in patients suffering from psychosis. Combined cognitive-behavioural therapy and motivational interviewing seems a promising psychological intervention to achieve a cessation of cannabis use in patients suffering from schizophrenia. SUMMARY: Further research is needed to understand the biological mechanisms underlying the effects of cannabis on mental health, but intervention strategies to help patients abstain should currently be implemented in psychiatric services, and public education campaigns should be directed at increasing awareness of the health risks of cannabis.
