Marijuana by Mouth: Seriously, It’s No Toke
You can’t have your cake and eat it too but you can have your marijuana without smoking or inhaling it — or even baking the weed into brownies.
That’s the message of Canadian medical marijuana purveyors, arriving just in time for this National Non-Smoking week.
It’s good news for people who use marijuana to quell nausea, anxiety and pain that may accompany cancer treatment or other chronic health issues.
A decision last year by the Supreme Court made it legal for Canadians to use non-dried forms of marijuana, and licensed medical marijuana producers have been developing alternative forms of the drug.
This month, CanniMed Ltd., based in Saskatoon, was granted a licence by Health Canada to manufacture and sell edible cannabis oils.
Cannimed CEO and president Brent Zettl says the company has had inquiries about the oil from five different countries and received about 700 Canadian orders the first week the oil became available.
What exactly is cannabis oil and how do you use it?
According to Zettl, food-grade alcohol is pumped through compressed cannabis flower material to extract the medicinal ingredients.
The alcohol and excess water evaporates and pure cannabis resin remains.
Olive oil is added and the mixture is heated to activate the medical ingredients. There’s no need for patients to provide additional heat — with a vaporizer or by lighting up — as is necessary with herbal cannabis.
Finally, additional olive oil is added and the product is bottled and packaged with an oral syringe. Patients can swallow the drops or place them under the tongue to be absorbed.
Six mL of cannabis oil is equivalent to one gram of dried cannabis.
But because the delivery method is different, the doses may not coincide.
Cannabis oil goes through the digestive system and the liver before going into the blood stream, explains Zettl.
Inhaling the dried product gets it into the blood stream right away through the lungs.
The oil may take an hour or more before taking effect and up to four hours to reach peak effect. But the effect does last longer.
New users of the edible oil are advised to start with a very low dose.
“Start low and go slow,” suggests Zettl. “You should definitely wait three or four hours before dialling up. The worst thing is take too much and have a bad reaction. If you start really low and have no reaction, that’s a good thing.”
Zettl says clinical trials now underway will likely lead to broader access to medical marijuana.
