Frequently asked questions How long until I receive my letter in the post? Yes, a hard copy of your recommendation letter and card (if requested) will be sent to the address provided on your application for. This usually takes between 2 – 5 days. However, you can sometimes expect to wait up to 35 days for a hard copy in some jurisdictions, as the MMP is sometime loaded with applications. In the meantime, you can use the recommendation letter we email to your inbox immediately to access dispensaries. Just show the receptionist the letter (either print it out or have it on your smartphone), and they will be able to verify your patient number. Once verified, you can enter the dispensary.
