Links to scientific, peer reviewed, cannabis related research


Recommended Posts

Hi everyone. I've been thinking about starting a thread like this so I don't forget all the cannabis related articles I read, and so others have the opportunity to read them too.

 

Please feel free to add to the thread, but please only add scientific peer-reviewed articles.

 

I actually found this one mentioned on the NCPIC website, I imagine they have no idea what the articles they mention are about and have already spotted some pro canna ones in there.

 

This one has some interesting info regarding yeilds of illicitly grown cannabis, and may be helpful when challenging estimations of yeild made by the police when they steal your babies.

 

Even mentions scrogging :thumbsup:

Plenty more to come when I have some spare time.

This is a quote from the above article, seriously guys do some research there are some really interesting articles out there in the big wide world.

 

Cannabis plants were uniformly treated with fertilizers that were added to the irrigation water. Fertilization and light regime were performed according to the Canna Terra grow scheme (except for the application of root stimulator Growstar® ‘Gold Excelerator’) that according to Belgian federal police is frequently applied in illicit cannabis cultivation (Table 1). The scheme was found at http://www.onlinegrowsupplies.com/CANNA_Terra_kweekschema.pdf (last visit: 19 May 2011). Fertilizers and other additives were obtained from illicit plantations that were confiscated by the Belgian federal police. Terra Vega™ (NPK 3-1-4) and Terra Flores™ (NPK 2-2-4) fertilizers stimulate vegetative growth and flowering, respectively. Growstar® Gold Excelerator™ is a root stimulator in which auxins (no further specification) are active components. Cannazym™ is, according to the label, an enzyme mixture (not specified) which is claimed to enhance mineralization of organic soil material, such as dead roots. Cannaboost™ is advertised on its label as an additive which improves photosynthesis. Although some websites claim that the active substance in Cannaboost™ is the natural growth stimulant triacontanol (C30H61OH), no reliable information on the composition of Cannaboost™ was found. PK13/14™ (NPK 0-13-14) is added during one week in the middle of the flowering stage in order to support the intensive flowering in that period. Irrigation water was applied every two days in amounts that were arbitrary determined on the basis of plant requirements.

Legalisation of medicinal cannabis in New South Wales

 

 

 

 

 

Graham Irvine, Southern Cross University

 

 

 

 

Abstract

 

Ever since cannabis pharmaceuticals were removed from official pharmacopeias in the Western world in the mid-twentieth century there have been ongoing campaigns to re-legalise medicinal cannabis. This political and social struggle for legalisation tends to be cyclical, with its proponents and detractors fluctuating between characterising its use as a form of deviance through to viewing it as a legitimate response to serious medical conditions.

 

This thesis poses the research question, ‘Is there a case for reform of the law to allow for the use of cannabis for medicinal purpose in New South Wales?’

 

The thesis is written for the thousands of seriously ill people who could benefit greatly from medicinal cannabis if it were legal and available. It addresses the what, who, how and why of the topic, only omitting ‘when’ which is a function of political timing beyond the scope of this study. Throughout it utilises forms of risk/benefit analysis, mindful of the potential hazards of the drug while being cognisant of its unique properties. It is designed to function as an evidentiary base for use by health care advocates, activists and reformist politicians seeking to raise the issue of medicinal cannabis with a view to initiating legislation, initially in the state of New South Wales and subsequently in all Australian states and territories.

 

Adopting a multi-disciplinary triangulated methodology, the thesis sets out to assess the evidence for medicinal cannabis legalisation. This includes a narrative of my own experiences with Parkinsons disease, the jurisprudential and criminological issues raised, whether there is sufficient evidence of the efficacy of medicinal cannabis to warrant its legalisation and whether there is a large enough constituency of potential medicinal cannabis users to render legalisation politically feasible.

 

After examining the history of medicinal cannabis use both overseas and in Australia, the study examines overseas and Australian legislation and case law, dissects three case studies explaining some pitfalls of drug research, a legal defence for medicinal cannabis arrestees and an ethical and safer source of medicinal cannabis. The remaining chapters draw out the implications of the data for the preparation of proposed New South Wales’ legislation.

Hopefully it atttatches properly somewhere.

 

Haven't read it yet and it is an extensive document (around 300 pages), but it looks very promising for anyone looking to educate themselves on a wide range of issues regarding medicinal cannabis in NSW.

That last one was a bit heavy so here's one for those of you that are more hands on. This is where it is at in terms of tissue culture of Cannabis. Also gives a good idea of how cannabis is grown in a scientific manner.

 

Lata, H., Chandra, S., Khan, I. A., & ElSohly, M. A., (2010). High Frequency Plant Regeneration from Leaf Derived Callus of High Δ9-Tetrahydrocannabinol Yielding Cannabis sativa L.. Planta Medica, 76, 1629-1633.

 

Here's just an example.

This one is interesting and also really funny. Best spidermite infestation ever :thumbsup:

 

The results of an indoor hydroponic Cannabis growth study are presented. It is intended that this work will be of assistance to those with an interest in determining an estimation of yield and value of Cannabis crops. Three cycles of six plants were grown over a period of 1 year in order to ascertain the potential yield of female flowering head material from such an operation. The cultivation methods used were selected to replicate typical indoor hydroponic Cannabis growing operations, such as are commonly encountered by the New Zealand Police. The plants were also tested to ascertain the percentage of the psychoactive chemical D-9 tetrahydrocannabinol (THC) present in the flowering head material, and were genetically profiled by STR analysis. Phenotypic observations are related to the data collected. The inexperience of the growers was evidenced by different problems encountered in each of the three cycles, each of which would be expected to negatively impact the yield and THC data obtained. These data are therefore considered to be conservative. The most successful cycle yielded an average of 881 g (31.1 oz) of dry, groomed female flowering head per plant, and over the whole study the 18 plants yielded a total of 12,360 g (436.0 oz), or an average of 687 g (24.2 oz) of dry head per plant. THC data shows significant intra-plant variation and also demonstrates inter-varietal variation. THC values for individual plants ranged from 4.3 to 25.2%. The findings of this study and a separate ESR research project illustrate that the potency of Cannabis grown in New Zealand has dramatically increased in recent years. DNA analysis distinguished distinct groups in general agreement with the phenotypic variation observed. One plant however, exhibiting a unique triallelic pattern at two of the five loci tested, while remaining phenotypically indistinguishable from three other plants within the same grow.

Cannabidiol Reduces the Anxiety Induced by Simulated Public Speaking in Treatment-Naı¨ve Social Phobia Patients

 

Neuropsychopharmacology (2011) 36, 1219–1226

 

Generalized Social Anxiety Disorder (SAD) is one of the most common anxiety conditions with impairment in social life. Cannabidiol

(CBD), one major non-psychotomimetic compound of the cannabis sativa plant, has shown anxiolytic effects both in humans and in

animals. This preliminary study aimed to compare the effects of a simulation public speaking test (SPST) on healthy control (HC) patients

and treatment-naı¨ve SAD patients who received a single dose of CBD or placebo. A total of 24 never-treated patients with SAD were

allocated to receive either CBD (600 mg; n¼12) or placebo (placebo; n¼12) in a double-blind randomized design 1 h and a half before

the test. The same number of HC (n¼12) performed the SPST without receiving any medication. Each volunteer participated in

only one experimental session in a double-blind procedure. Subjective ratings on the Visual Analogue Mood Scale (VAMS) and Negative

Self-Statement scale (SSPS-N) and physiological measures (blood pressure, heart rate, and skin conductance) were measured at six

different time points during the SPST. The results were submitted to a repeated-measures analysis of variance. Pretreatment with CBD

significantly reduced anxiety, cognitive impairment and discomfort in their speech performance, and significantly decreased alert in their

anticipatory speech. The placebo group presented higher anxiety, cognitive impairment, discomfort, and alert levels when compared with

the control group as assessed with the VAMS. The SSPS-N scores evidenced significant increases during the testing of placebo group that

was almost abolished in the CBD group. No significant differences were observed between CBD and HC in SSPS-N scores or in the

cognitive impairment, discomfort, and alert factors of VAMS. The increase in anxiety induced by the SPST on subjects with SAD was

reduced with the use of CBD, resulting in a similar response as the HC.

Very interesting articles. I have a large collection of literature in my Endnote library - less scientific stuff on growing, but more qualitative / sociological articles on drugs, drug policy, etc.

 

I like this article by my Belgium colleague:

Decorte, T. (2010). Small scale domestic cannabis cultivation: An anonymous Web survey among 659 cannabis cultivators in Belgium. Contemporary Drug Problems, 37, 341-370.

 

Be interested to hear your thoughts on any differences between Belgium growing and here.
