How to Store Your Cannabis Medicine Safely

Storing your medical cannabis correctly helps keep it safe, effective, and within the law. This guide explains how to store different forms of medication, protect those around you, and ensure your prescription remains secure and compliant.

Storing your medical cannabis correctly is important to keep it safe, effective, and compliant with UK law. Whether you are prescribed flowers, oils, or cartridges, following a few simple guidelines will help protect your medication and the people around you.

Keep it in its original packaging.

Always store your cannabis in the packaging the pharmacy dispensed it in. This is important because:

  • It contains your prescription label
  • It shows that your medication is legally prescribed to you
  • It includes important information such as dosage and expiry date

Avoid transferring your medication into other containers unless advised by your clinician or pharmacist.

Store in a cool, dry place

Medical cannabis should be kept:

  • Away from direct sunlight
  • In a cool, dry environment
  • At a stable room temperature

Heat, light, and moisture can affect the quality and effectiveness of your medication.

Keep it out of reach of children and pets

Cannabis medicines should always be stored safely and securely:

  • Keep them out of sight and reach of children
  • Store them in a locked cupboard or container if possible
  • Ensure pets cannot access them

Even small amounts could be harmful if accidentally consumed.

Keep your medication secure.

As a controlled drug in the UK, medical cannabis should be stored responsibly:

  • Avoid leaving it in shared or public spaces
  • Do not carry more than you need when outside the home
  • Keep it secure when travelling

If you are taking your medication out with you, make sure it remains in its original packaging.

Be mindful of expiry dates.

Like all medications, cannabis products have expiry dates. Using them after this time may reduce their effectiveness.

Check your packaging regularly and speak to your pharmacy if you are unsure.

Do not share your medication.

Your prescription is specific to you. It is illegal and unsafe to share your cannabis medicine with others, even if they have similar symptoms.

Travelling with medical cannabis

If you need to travel:

  • Keep your medication in its original packaging
  • Carry a copy of your prescription or clinic letter if possible
  • Check the rules if travelling abroad, as laws vary by country

Disposal of unused medication

If you have unused or expired medication:

  • Do not throw it in the household waste
  • Do not flush it

Instead, return it to a pharmacy for safe disposal.

Important: Safe storage helps protect your health, ensures your medication remains effective, and keeps you within the law.
