The truth behind how cannabinoids and terpenes work in therapeutic mixtures is more complicated than has been reported in the popular press.

Following the promising study on cannabinoids and COVID-19 published by Oregon State University, Gb Sciences, Inc., a plant-based biopharmaceutical research and development company, has advised that the truth behind how cannabinoids and terpenes work in therapeutic mixtures is more complicated than has been reported in the popular press.

Gb Sciences’ study with Michigan State University (MSU) has yielded preclinical data demonstrating that specific compounds and ratios of those cannabis compounds are likely to be required for cannabinoids to be used to treat COVID-19 symptoms.

woman

Local cannabis store manager disputes claims, contends 'it's all about education' and finding the right type and correct dose

A local mental health advocate is speaking out about what she considers the potential risks of cannabis use.

Zoey Raffay, a published author and former student at Orillia Secondary School, says she has not consumed cannabis recently, and her mind is as clear as ever.

“I find that cannabis really struck my psychosis, my depression, and anxiety," said the 21-year-old.

"It made it all skyrocket and it made my medications go up. Now that I’ve been off it, it’s been amazing. In the long-term, cannabis doesn’t help with things like depression and anxiety. I found it just made It worse."

Cannabis: Increased schizophrenia risk in young people linked to both low and high use

crazy woman

"While we can clearly see there’s an association between cannabis use and schizophrenia in young people, we still can’t actually be sure that cannabis causes it."

An estimated  200 million people  use cannabis across the world. Next to alcohol and tobacco, it’s the most widely used drug in many countries. But while many may  no longer see  cannabis as a risky or harmful substance, there are still many things experts don’t know about cannabis – including why some people develop schizophrenia after use.

Researchers have been investigating the connection between cannabis use and schizophrenia  since the late 1960s . Since then, research has confirmed a link between cannabis use and  greater risk of developing schizophrenia .

"Further studies are needed to determine if reversal of these observed adverse effects would occur if THC was discontinued and for validation of the findings in a human cohort.”

Scientists at Oregon Health & Science University (OHSU) say that non-human primates administered cannabis edibles daily experienced a significant adverse effect their fertility and reproductive health.

“Our analysis of the collected samples found that THC use was associated with significant adverse impacts to the animals’ reproductive hormones,” reports Dr. Jamie Lo, the study’s senior author and an associate professor of obstetrics and gynecology with the Oregon National Primate Research Center at OHSU.

Marijuana is a risky choice for drivers

driver

Surely it’s not beyond the ability of Health Canada to come up with a users’ guide that could be handed out at cannabis stores.

Since the use of cannabis was legalized in 2018, the number of drivers injured while testing positive for the drug has more than doubled.

Specifically, the proportion of injured drivers who had blood concentrations above the legal limit stood at 3.8 per cent in 2018. By 2020 that number had risen to 8.6 per cent. The greatest increase was in drivers over 50 years of age.

While more recent figures aren’t available, such a dramatic surge in just two years suggests an ongoing trend.

A new study has found that cannabis use in both recreational and chronic users can lead to persistent and severe acute cognitive impairments that may continue well beyond the period of intoxication.

The systematic review of 10 papers and more than 43,00 participants, led by Canadian researchers and published Wednesday in the scientific journal Addiction, found that cannabis intoxication can produce small to moderate cognitive impairments in areas such as decision making, suppressing inappropriate responses, and the overall time needed to complete a mental task.

The review also found that the ability to remember what one reads or hears, as well as learning through reading and listening, were also impacted.

Cannabis legalisation does not lead to increased psychosis or schizophrenia, Canadian study shows

drug

One of the arguments used all across the world against the legalisation of cannabis, that its use leads to increased cases of schizophrenia and psychosis, was dealt a blow this week. Evidence from a Canadian study shows that hospital admission for cases of cannabis-induced schizophrenia and psychosis have not risen since the Canadian government legalised adult cannabis use in 2018.  

In the study, published in the Canadian Journal of Psychiatry, researchers state that they aimed to directly address the often reported fear “that legislation might increase the burden of transient and persistent psychotic illnesses in society.”

A study last week from two Oregon universities has generated a lot of buzz, after findings suggested that some cannabis compounds may be able to block the SARS-CoV-2 virus from entering human cells. It adds to a growing body of research on cannabis and the coronavirus, as studies from around the world — including from Canada — have found that the cannabis compound CBD may be effective in helping treat some of the virus’s most deadly symptoms.
