Types of research with cannabis

The Cannabis Act (the Act) and the Cannabis Regulations (the Regulations) authorize activities with cannabis, including research.

The purpose of this page is to help you decide what cannabis licence you may need for a research study.

Research studies

You can refer to the decision tree below to help decide what type of cannabis licence you may need. You can find more information about each type of study below.

Figure 1 - Text description

Start: Will you be conducting research with any of the following:

  • With humans: Go to With humans
  • With animals
    • You may need a research licence. You may also need to obtain other authorizations from Health Canada.
  • With neither animals nor humans: Go to With neither animals nor humans

With humans

  • Does the study protocol include information about which participants will or will not be administered cannabis and the level of exposure to the cannabis?
    • Yes: Does the study intend on assessing non-therapeutic effects of cannabis?
      • Yes: You may need a research licence.
      • No: This may be a clinical trial. You would need to file a clinical trial application as well as apply for a cannabis research licence.
    • No: This may be an observational study. An observational study does not require a cannabis research licence.

With neither animals nor humans

Are you looking to conduct research activities including: in vivo or in vitro studies, plant genetics, cannabis product development, non-cannabis product development, synthesis, indoor/outdoor cultivation of cannabis or hemp, or other?

  • Yes: Do you currently have a licence for cannabis cultivation, processing, analytical testing or a cannabis drug licence?
    • Yes: You may be able to use your current licence for research and development activities.
    • No: You may need a research licence.
  • No: You may not need a cannabis research licence. Refer to the Types of cannabis and industrial hemp licences to find out if a different cannabis licence may be more suitable.

To conduct research and development with cannabis, you may need to apply for a research licence. Refer to the Cannabis licensing application: Research licence for more information on research licence applications.

As an adult or an organization, you may conduct cannabis research without a licence if you meet all these criteria:

While conducting this research, you may: 

However, you are not permitted to cultivate, propagate or harvest cannabis without a licence.

If you have a cannabis drug licence or a licence for cultivation, processing or analytical testing, you are already authorized to conduct certain research activities (such as chemical characterization of cannabis or certain in vitro tissue culture studies). These activities must be within your authorized activities according to the Regulations. If you want to conduct research outside of your authorized activities, you need to apply for a research licence.

For more information on research activities, refer to Types of cannabis and industrial hemp licences.

Research studies involving human participants

There are 3 types of research studies with cannabis involving human participants:

NTRC and clinical trials are both interventional studies where researchers administer and distribute cannabis to study participants. NTRC studies investigate non-therapeutic effects of cannabis, while clinical trials can investigate therapeutic and non-therapeutic effects of cannabis.

Therapeutic effects can include:

Non-therapeutic research on cannabis (NTRC)

NTRC are interventional, non-therapeutic studies with cannabis regulated under the Act and its regulations.

The purpose of NTRC is to:

An example of an NTRC study is assessing participants in a driving simulation test to find out how long they are impaired for after researchers have administered cannabis.

If you want to conduct an NTRC study, you need to apply for a research licence under the Act and its regulations. For the NTRC application requirements, refer to Cannabis licensing application: Research licence.

Clinical trials

Clinical trials with cannabis are interventional studies regulated under the Food and Drugs Regulations.

Clinical trials aim to gather evidence to help bring new therapeutic products to market or inform clinical practice. Researchers may use them to:

An example of a clinical trial with cannabis could include studying whether a specific form of cannabis could ease pain.

These questions can help you decide if your research study may be a clinical trial:

If you answer yes to any of these questions, your study may be a clinical trial under the Food and Drugs Regulations.

If you want to conduct a clinical trial with cannabis, you will need both:

For more information on clinical trials with cannabis, please see the Clarification of requirements when conducting clinical trials with cannabis.

Important: You can choose to study cannabis for non-therapeutic purposes under the Act and its regulations (as NTRC) or the Food and Drugs Act and its regulations (as clinical trials). Each framework has specific requirements you must follow. If the study involves investigational drugs or pediatric patients, it must follow the Food and Drugs Act framework. A cannabis research licence is required for both clinical trials and NTRC.

Observational studies

Observational studies with cannabis are non-interventional studies that are limited to recording observations and analyzing data. These types of studies do not require approval from Health Canada. A researcher conducting an observational study is not permitted to conduct any activities with cannabis that involve possessing, distributing or administering cannabis to participants.

While you do not need authorization from Health Canada to conduct observational studies with cannabis, you should check with your Research Ethics Boards about applicable ethics requirements.

An example of an observational study could be asking participants to fill out a questionnaire on how they felt after consuming cannabis products that both:

Other types of research studies

Research studies for veterinary purposes

For research studies to be conducted using a veterinary drug, the objective is to ensure that there is appropriate oversight for the overall health and safety of study animals.

In order to conduct veterinary drug research using drugs containing cannabis, the investigator or the sponsor is required to submit an Experimental studies certificate application. If the study includes food-producing animals, Health Canada also considers relevant information to address food safety. Depending on the details of the study being considered, you may need to obtain other authorizations before you begin.
