“Are we allowed to grow our own plant? If so how many and how high.”

Yes, New Brunswickers will be allowed to grow their own plants - up to a max of 4 per dwelling. There are not restrictions on height of plants, but there is a line in the N.B. Cannabis Control Act that dictates minimum height for an enclosure required for outdoor cultivation.

For further detail, have a look at the links at the bottom of the Good Information page - there you can access both the federal and provincial acts and have a more complete look at their respective Cultivation sections.
