To date, Canada has not approved the use of cannabis for therapeutic purposes. This means that there are no cannabis products that have been granted a Drug Identification Number (DIN).

That said, there are some plans that may cover cannabis. To find out, you should check the terms and conditions of your insurance plan.


The Veterans Affairs Canada program has a maximum reimbursement limit of 3g/day. For any amount exceeding this, an attachment with additional information must be completed by the prescribing health practitioner.

For more details, please visit this link.

In terms of group or private insurance programs, insurers are becoming more receptive to the use of cannabis for therapeutic purposes. In order to obtain reimbursement with insurers who accept it, certain conditions must be respected, such as

  1. a) Therapeutic cannabis must be prescribed by a health care practitioner (either a physician or a nurse practitioner) with a valid licence for a medical condition recognized by the insurer.
  2. b) You must register with a Health Canada licenced producer and only purchase products from licenced producers.

Ask your insurer about the restrictions and conditions to obtain reimbursement.


As the two products are administered by different routes, the main difference is in the onset and duration of action. Inhalation or vaporization have a faster onset of action because the substance enters the bloodstream more directly through the respiratory tract and would have a shorter duration of action. Ingestion may lengthen the onset of action considerably, but users would report a longer duration of action.


The packaging date is always on the container of the product you purchased, whether it is recreational or medical. This date refers to when the finished product was packaged in the container you are purchasing. Cannabis, even if it has been in your home for several months, is still safe to consume, but as time goes on, the product will be less fresh.

Since Health Canada does not currently impose an expiration date, most producers do not put one. That said, you can consult the section on the conservation of cannabis in order to keep it in the best possible environment, and thus, preserve its freshness.


It is important to store cannabis properly because improper storage could reduce its freshness and potential. There are 4 main factors to consider when it comes to cannabis storage:

TEMPERATURE: The ideal storage temperature for the cannabis flower is between 19 and 21 degrees Celsius (66.2 to 69.8 degress Fahrenheit). On the one hand, if the temperature is too low, the trichomes will tend to become fragile and more easily degrade. Also, storage in the freezer produces condensation and this can promote the appearance of mold, as well as temperatures too high (25-30 degrees Celsius or 77-86 degrees Farenheit).

HUMIDITY: The humidity of a product is simply its water content. The ideal storage humidity for cannabis flower is a relative level of 60-66%. If, after opening your product, the product is stored airtight, the moisture content of the product should be preserved for some time. Since temperature variations can change the humidity level, a cooler location is suggested. Humidity regulators can be useful at times, as they can remove excess moisture or add moisture, depending on the need of the product.

LIGHT and AIR: While light can alter the taste, dry out the product or accelerate the degradation of terpenes, air contributes to the drying of dried flowers. An airtight jar is therefore suggested to recreate an adequate environment for the conservation of the product. If the container is translucent (like glass), you can keep it in a dark place like a cupboard.

SAFETY: In addition to preserving the quality and freshness of a product, proper storage must consider the safety aspect. It is strongly recommended that cannabis products be stored out of reach of children and pets. It is also recommended that products that are changed from one container to another be clearly identified as to their composition and concentration. Finally, it is suggested that cannabis products be stored in a different location than everyday products to avoid accidents.

** In case of intoxication, contact emergency services.




The flower (flowering top, bud, cola)

This is the part that distinguishes males from females. While males mature before females, male plants have stamens and anthers that contain pollen to fertilize the female plant.

It is important to separate the males from the females as soon as it is possible to tell them apart (using the white hair) so that the female is not fertilized, because if it is, it will concentrate on producing seeds rather than large and healthy flowers.

The flowering tops, according to the species, can take various colors such as orange, green or even certain purple accents and it is them which contain the greatest concentration of cannabinoids through the trichomes which develop there.

The leaf

The leaf can be helpful in determining the type of cannabis you are dealing with. The stockier, shorter, darker leaf is usually indica, while the longer, lighter leaf is usually sativa. Hybrids can obviously have characteristics of both species.

The leaves of the cannabis plant are used for the photosynthesis of the plant, where from the importance not to defoliate too much the plant so that it does not lack energy.

The pistils

The pistils are like small hairs which change gradually from white to yellow, then to orange, then to brown-amber. If you see them on the flowers of the plant, it is a female. The role of the pistils is to collect pollen to reproduce.

Bracts and calyxes

The bract is what encloses the reproductive system of the female and looks like a kind of “leaf” in the shape of a tear. The bract is covered with glands which produce resin having the highest concentration of cannabinoids, all parts of the plant considered.

The calyx, as for it, is a colorless layer being used to protect the ovula at the base of the flower. It is besides from this place that the pistils being used to catch the pollen grow.


Trichomes are the small crystals that can be seen on the surface of cannabis flowers and, in smaller concentrations, on the leaves. Cannabinoids and terpenes are found in the trichomes, which are transparent at the beginning and gradually change with the evolution of the bloom and take a more and more milky tint. It is besides a good indicator for the cultivators on the moment of harvest.

If you want to make sure that the supplier you intend to do business with is a licensed producer in Canada, you can go to this site for validation.


Cannabis can be smoked (inhalation by joint, bong, pipes, etc.), absorbed in the form of vapor (vaporization without burning the dried flower), consumed orally (edible products, for example), taken sublingually (with an oil left under the tongue, for example), applied topically (cream) or rectally (suppositories).

The pharmacokinetic (what happens to the substance in the body) and pharmacodynamic (what the substance does to the body) properties vary depending on the route of administration.


If cannabis is a new substance in your life or if you used it a long time ago, it cannot be said enough: Start LOW and go SLOW. Depending on the route of administration selected, the effects can be different and when cannabis is ingested, it is less easy to dose the amount since it takes longer to produce an effect. And even though it is easier to measure the amount with inhalation, it can also happen that you go over your own limit and don’t feel good.

Click here for tips you can follow to make this uncomfortable moment go away more easily.

Of course, these tips are not a substitute for seeing a health care professional. If you don’t feel better, it may be best to consult a professional.


As is customary in the field of medical cannabis, starting with small amounts is best. It is even suggested to start with half the dose recommended by your practitioner.

The goal is to know yourself and your reactions to the substance. We suggest, before starting, that you take care to evaluate yourself BEFORE, DURING and AFTER taking the product. This will allow you to know exactly what dose will bring the best therapeutic effect without taking too high a dose.

You can click here to get suggestions on what information to compile in order to keep a consumption journal to properly target your needs.

Mixing cannabis and alcohol is not recommended. According to Health Canada’s “Reducing the Risk of Cannabis Use” (you can read it here), mixing alcohol and cannabis may lead to greater impairment and more adverse effects.


It is true that all these products can be confusing when you don’t know which product to use for your needs.

If this is your case, it may be wise to call on our Canna-Expert or CannabiNurse service to better guide you through this sea of possibilities!

You can make an appointment with one of them via the home page of this site, by clicking on “Talk to our Cannabis Expert or Nurse” or by going to one of our Facebook pages, either JMF Growers or, by clicking on the “Book” button.


First of all, you don’t have to feel intimidated by this conversation. Your doctor’s role is to make sure you are well and getting the care you need, so it is important to keep that in mind.

However, here are some tips that may help you prepare for this discussion and have what your doctor needs to assess your situation:

  1. Do some research on your own. It may be a good idea to have compiled information related to your illness and/or symptoms and cannabis treatments. It may be helpful for your doctor to have information about how cannabis has helped others in your situation, including anything about dosages and frequency of use. Anything you can get your hands on may be helpful in supporting the conversation.
  2. As part of your research, it may be a good idea to look at the different strains and their potential effects as well as the different routes of administration of the product. This way, you can discuss the best options with your doctor.
  3. It may be worthwhile to suggest a trial period to your doctor so that you can both evaluate the effects of the strains, dosages and frequencies to find what works best for you.


Cannabis & Law Questions :


It is a criminal offence to drive and use an impairing substance. Cannabis can impair a person’s faculties, so it is illegal to use this substance and drive a vehicle. In addition to the risk of an accident, impaired driving can result in a ticket and even prosecution and jail time.

You can learn more about driving while impaired by cannabis from the INSPQ (Public Health expertise and reference center in Quebec) by clicking here (French only) or from Health Canada by clicking here.


It is possible to travel with cannabis for medical purposes within Canada. However, it is not permitted to cross the border into the country. It is important that if you are travelling with your medical cannabis, that you have your prescription document and that your products are in their original packaging. We also suggest that if you are flying, you contact the airline to ensure that possession is permitted.

For more information, consult this link from Health Canada.

Also, it is important to consider the maximum amount of cannabis you can carry when travelling. It is illegal to possess more than the equivalent of one month’s prescription up to a maximum of 150g, in addition to the 30g recreational allowed.
