Understanding the Limits: What ACMPR License Holders Need to Know About Cannabis Possession and Storage

The Access to Cannabis for Medical Purposes Regulations (ACMPR) sets specific guidelines for the possession and storage of medical cannabis. These guidelines are not merely suggestions but are in fact legal requirements that all ACMPR license renewal holders must adhere to. Failure to do so can result in penalties, including the potential revocation of your license. Here’s a breakdown of what you need to know about these regulations.

Possession Limits

Under the ACMPR, the possession limit for medical cannabis is generally tied to your healthcare provider’s prescription, but there is an upper limit. Specifically, you can possess the lesser of 150 grams or a 30-day supply of your prescribed amount of dried cannabis (or the equivalent in another form). It’s crucial to understand these limits and to ensure that at no time do you exceed them.

Storage Limits

Unlike possession limits, which are well defined, storage limits can be a bit murkier. The ACMPR doesn’t specify a maximum amount you can store at home, but it’s implied that you should only store what is reasonable for personal medical use. However, if you are cultivating your own cannabis, you should keep within the plant count and gram limits as indicated in your license.

Public vs. Private

The rules about where you can and cannot possess cannabis are also worth noting. While you may have the legal right to possess medical cannabis, there are restrictions on where you can consume it, especially in public areas. Always check local laws and regulations, as they can differ widely.

Traveling with Medical Cannabis

When traveling within Canada, ACMPR license holders are permitted to carry their medical cannabis with them. However, international travel with medical cannabis is more complicated and is generally not advised due to differing laws on cannabis in other countries. If you must travel domestically, always keep your medical documents and ID handy for verification.

Packaging and Labels

When storing cannabis, it should be kept in its original packaging with all labels intact. These labels contain vital information, including the product’s cannabinoid profile and expiration date, which can be crucial for both your use and for legal verification purposes.

Safeguarding Your Supply

Regardless of the storage limits, it’s imperative that you take measures to store your cannabis securely. This is not only good practice but also a requirement in many jurisdictions. Secure storage can include lockable containers or even a dedicated locked room, depending on the amount of cannabis being stored.


Maintaining a record of your medical cannabis use, including the amounts you have purchased, used, and currently have in storage, can serve as additional protection in case of legal inquiries. It also helps you keep track of your usage patterns, which can be useful information for your healthcare provider.

Compliance Checks

Be prepared for potential compliance checks from Health Canada or local authorities. Make sure that your storage and possession practices adhere to all guidelines, and always keep your medical documents accessible for such instances.

Understanding the specific rules about cannabis possession and storage under the ACMPR is essential for anyone using medical cannabis. Staying within these legal parameters ensures uninterrupted access to your medicine and helps avoid any legal complications.
