The potency concentration or strength of THC in cannabis is often shown as a percentage of THC by weight or by volume of an oil. Cannabis that contains very low amounts of THC in its flowers and leaves less than 0. Cannabidiol CBD is another cannabinoid. CBD is also being studied for its possible therapeutic uses. Terpenes are chemicals made and stored in the trichomes of the cannabis plant, with the cannabinoids. Terpenes give cannabis its distinctive smell.
The cannabis plant is used for its effects on the mind. It is also used for medical, social or religious purposes. Marijuana is a slang term for the dried flowers, leaves, stems and seeds of the cannabis plant. Results of the Canadian Cannabis Survey provide a snapshot of how much cannabis Canadians use, how often they use it, and in what form.
Most cannabis products come from or can be made using the flowers and leaves of the cannabis plant. Table 1 lists the main forms of cannabis and typical potencies of THC. Not all forms of cannabis are yet available for legal sale under The Cannabis Act that came into force on October 17, The Cannabis Act currently permits the sale of:. The sale of edibles containing cannabis and cannabis concentrates would be permitted within 1 year after the coming into force date of the Cannabis Act.
You will not receive a reply. Another indicator for a higher psychosis risk is the presence of subclinical psychotic features and again such individuals have been affected by a higher risk of developing a psychotic illness [ Henquet et al.
Furthermore those who are at ultra high risk for psychosis have been reported to be more sensitive to the psychotogenic effects of cannabis compared with users in the general population [ Peters et al. Because of the reported links between the schizotypal personality and schizophrenia, this type of personality disorder has come under scrutiny in examining the role of cannabis in producing psychotic symptoms.
Indeed, it has been shown that people scoring high in schizotypy who use cannabis are more likely to have psychosis-like experiences at the time of use, together with unpleasant side effects [ Barkus et al. This study has been replicated and it has been confirmed that those with schizotypal personality disorder carry a higher risk of experiencing psychotic symptoms with cannabis use [ Stirling et al.
Most recently, another study has provided further support for a strong association between early cannabis use and the development of schizophrenia spectrum disorder symptoms [ Anglin et al. The reported vulnerability factors mentioned here imply a strong genetic predisposition and there have been a number of studies looking particularly to specific genes which have been implicated in psychoses. The first such study was carried out by Caspi and colleagues [ Caspi et al.
In this longitudinal study, a specific susceptibility gene which has been linked to schizophrenia and bipolar disorder, catechol-O-methyltransferase COMT , was examined in a representative birth cohort followed to adulthood.
The study found that carriers of the COMT valine allele were most likely to exhibit psychotic symptoms and to develop schizophreniform disorder if they used cannabis before the age of However, the number of people carrying this allele was small in this study. Using a case-only design of people with schizophrenia, Zammit and colleagues re-examined this association but their findings did not support the different effects of cannabis use on schizophrenia according to variation in COMT [ Zammit et al.
More recently, van Winkel and colleagues looked at the effects of recent cannabis use whilst examining single nucleotide polymorphisms in 42 candidate genes in patients with psychosis and their unaffected siblings [ van Winkel et al. The authors found that genetic variation in serine-threonine protein kinase AKT1 may mediate both short- and long-term effects on psychosis expression associated with cannabis use. Further support for the possible involvement of the AKT1 gene comes from our study with healthy volunteers.
This study found that, during the encoding and recall conditions of the verbal memory task, the induction of psychotic symptoms by dTHC was correlated with the attenuated striatal and midbrain activation only in those who were G homozygotes of AKT1 and carriers of the 9-repeat allele dopamine transporter DAT1 [ Bhattacharyya et al.
Apart from schizotypal personality, the vulnerability factors to the psychotogenic effects of cannabis require replication. It is clear that further work needs to be carried out to explore the biological mechanisms which determine the vulnerability towards a psychotic outcome. During the last decade, endocannabinoid research has been one of the fastest growing fields in psychopharmacology, opening ways to discover new medicines for a wide variety of health problems, ranging from metabolic disorders, to glaucoma and schizophrenia.
The distribution of the endocannabinoid system in the brain is interesting as the very same brain areas are also implicated in psychoses, particularly in schizophrenia. Furthermore, complex and intricate involvement of this system with other neurotransmitters such as dopamine, GABA and glutamatergic systems may have implications for the development of a psychotic illness.
Naturally, due to the recent and constant increase in the availability of higher THC content variants of cannabis around the world, there have been increasing concerns about the health risks, particularly for young people. However, cannabis affects people differently and therefore it is important to understand what makes someone more at risk and how they differ compared with those who do not develop psychotic illness.
Here we have provided an overview of the available information on the risk factors which may make an individual more at risk, such as predisposition to psychosis, schizotypal personality and certain susceptibility genes. Finding groups who are vulnerable is particularly important so that they can be targeted for early preventative and therapeutic interventions. Such a search would also lead to the discovery of the biochemical mechanisms involved in cannabis and endocannabinoid research and ultimately to a better understanding of how the brain and the body functions.

Abstract Cannabis is a complex plant, with major compounds such as deltatetrahydrocannabinol and cannabidiol, which have opposing effects.
Cannabis, deltatetrahydrocannabinol, cannabidiol, tetrahydrocannabivarin, endocannabinoids, individual sensitivity to cannabis. Introduction Cannabis is a complex plant with over chemical entities of which more than 60 of them are cannabinoid compounds, some of them with opposing effects.
Brief history of the biochemistry of the cannabis plant Even though cannabis has been used and cultivated by mankind for at least years [ Li, ] our current knowledge on its pharmacological properties is based on studies which have taken place only since the end of the nineteenth century.
Open in a separate window. Chemical structures of deltatetrahydrocannabinol and cannabidiol. Cannabinoid receptor system Another cornerstone in cannabinoid research was the identification of the specific binding sites of dTHC in the brain [ Devane et al.
Cannabinoid 1 and 2 receptors CB1Rs are mainly in the brain, particularly in the substantia nigra, the basal ganglia, limbic system, hippocampus and cerebellum, but are also expressed in the peripheral nervous system, liver, thyroid, uterus, bones and testicular tissue [ Russo and Guy, ; Pagotto et al.
Functions of the endocannabinoid receptor system Available evidence indicates that we do not yet have a complete understanding of the varied functions of the endocannabinoid system, which is widely distributed both in the brain and in the peripheral system and most glands and organs in the body. Cannabis plant The cannabis plant has two main subspecies, Cannabis indica and Cannabis sativa , and they can be differentiated by their different physical characteristics.
Deltatetrahydrocannabinol and cannabidiol Natural compounds of the cannabis plant are also referred to as phytocannabinoids of which dTHC is the main psychoactive ingredient and has been widely researched both in animals and humans. Intersubject variation in response to the psychotogenic effects of cannabis About Proposed factors determining sensitivity to psychosis in cannabis users.

Conclusion During the last decade, endocannabinoid research has been one of the fastest growing fields in psychopharmacology, opening ways to discover new medicines for a wide variety of health problems, ranging from metabolic disorders, to glaucoma and schizophrenia.
