  • ACMPR requires you to secure any marijuana products and/or cannabis plants within your possession. These must be used for medical purposes and must remain secure so that others can’t access them, including children.
  • It is wise to take measures to ensure that others don’t know you are cultivating cannabis or marijuana products for your own medical use. Keep plants where they cannot be viewed from outside your home or yard. Also, try to limit aromas coming from your grow site.

Under this act, the boundary of the area where you grow cannabis outdoors cannot share common points with boundaries of land housing public playgrounds, schools or other public places frequently visited by minors under the age of 18 years old.
