Chief Medical Officers Issue Cannabis Warning
It may be legal but the Council of Chief Medical Officers of Health (CCMOH) have issued their second warning in less than three months about the potential dangers of using cannabis. The CCMOH is made up of the federal and all provincial and territorial chief medical officers.
In an October 25, 2019 statement the CCMOH said using cannabos did not come without risks.
“As with other regulated substances, such as alcohol and tobacco, cannabis is not harmless. While there is some evidence of potential therapeutic uses for cannabis, the long-term effects remain unknown, and more research needs to be done,” the CCMOH statement said, adding “Cannabis can be addictive, and frequent use can cause harm to your physical and mental health. In fact, close to 10% of adults who have ever used cannabis will develop cannabis use disorder. The younger you are when you start using cannabis, and the more often and the longer you use it, the more likely that it will have a negative impact on your brain.”
In their January 6,2020 statement the CCMOH continued to warn that like tobacco and alcohol was not harmless but there was some potential health benefits from use of the drug the best way to stay away from harmful effects was not to use it.
“While there is some evidence of potential therapeutic uses for cannabis, evidence continues to emerge on the longer-term health effects of cannabis, highlighting the importance of ongoing research. The only way to completely avoid the risks associated with cannabis use is to not use it,” the CCMOH statement read.
For those who imbibe in legal cannabis the CCMOH advised users to start low and go slow to minimize any adverse health risks. The CCMOH advised using products with lower amounts of tetrahydrocannabinol (THC) and equal or higher amounts of cannabidiol (CBD).
They further advised how a user consumed cannabis - orally or by inhalation - how much tetrahydrocannabinol (THC) or cannabidiol (CBD) consumed, and how quickly a product is consumed can influence whether or not users will potentially experience adverse effects.
The recent large numbers of lung related illnesses being reported from vaping had the CCMOH advising —the safest approach for people who use cannabis is to avoid smoking or vaping cannabis extracts.
For those who choose to vape cannabis extracts the CCMOH statement advised the following to help reduce health risks:
Use vaping products that have been obtained from legal, regulated sources only. Illegal or unregulated sources are not subject to any control or oversight and may pose additional risks to health and safety.
Use vaping products for their intended purpose only. Avoid modifying vaping products and do not add substances to products that are not intended by the manufacturer (such as products containing nicotine). If a product is not intended for vaping, do not vape it.
Limit the amount and frequency of consumption. Initial effects can be felt within seconds to minutes, but full effects can take up to 30 minutes to be felt. Begin with one or two puffs of a vape or joint with 10 percent (100mg/g) or less of THC.
Always read the label to understand the strength of the product. The concentration of THC (% or mg/g) can be found on the label on products that have been obtained from a legal, regulated source.
Avoid deep inhalation and breath-holding.
Avoid consuming other substances, such as alcohol, when using cannabis.
Cannabis products that do not involve inhalation such as orally consumed oils or tinctures, edible cannabis products, topicals or sprays, can be an option to avoid potential impacts on lung health, the CCMOH advised.
The CCMOH also issued warnings regarding cannabis edibles based upon how they often effected users differently than inhalation.
“Cannabis products that are swallowed or eaten can have psychoactive effects, or effects on mental processes, that can differ from those that are inhaled. Some people may experience stronger and more unpredictable effects from edible cannabis products than from inhaled products. In addition, delays in the onset of psychoactive effects from swallowed or eaten cannabis products can result in overconsumption and increase the risk of poisoning. Edible cannabis products can also carry a higher risk of accidental poisoning, especially in children and pets, because they can be mistaken for regular food and drink,” the CCMOH advised,
To minimize the risks associated with using edible or orally consumed cannabis products the CCMOH advised consumers the following:
Always read the label to understand the strength of the product. The total amount of THC in a single package of edible cannabis can be up to 10 mg, which would be a large amount for someone consuming cannabis for the first time or infrequently.
Label and store all cannabis securely. Edible cannabis may look like regular food such as baked goods or candy. Store them securely in clearly labelled containers or in their original, child resistant packaging, away from food products and out of the reach of children and pets.
Start with small amounts - 2.5 mg of THC or less for products that you eat or drink.
Wait until you feel the effects before taking more. It may take up to 2 hours to feel the effects of edible cannabis, and up to 4 hours to feel the full effects.
Remember not to drive or operate heavy equipment after using cannabis. Cannabis can impair coordination and concentration, and can impede your ability to make quick decisions. The effects from edible cannabis last 4 to 12 hours, with some effects lasting up to 24 hours.
If you experience any adverse effects from cannabis—including edible cannabis, cannabis extracts or topicals—seek appropriate health care and report side effects from cannabis products to Health Canada.
The CCMOH also stressed the potential for addiction to cannabis.
“Finally, when using any type of cannabis product, it is important to remember that like other substances, there is the possibility of developing cannabis dependence or addiction, and that frequent use can cause harm to your physical and mental health. In fact, close to 10% of adults who have ever used cannabis will develop cannabis use disorder. The younger you are when you start using cannabis, and the more often and the longer you use it, the more likely that it will have an adverse impact on your health. People who experience problems related to their use of cannabis can speak to a healthcare provider about evidence-based behavioral treatment and recovery options.”
