A Bill that would make it legal to grow your own medicinal marijuana will be debated in Parliament.

Green MP Julie Anne Genter's Misuse of Drugs (Medicinal Cannabis and Other Matters) Amendment Bill was drawn from the ballot on Thursday.

"At the moment people who are chronically ill or terminally ill who are using cannabis to relieve their pain or nausea, or for sleep, are currently operating outside of the law," Ms Genter told Newshub.

"My Bill would say that you're allowed to cultivate, possess and use cannabis if you have the support of a registered medical practitioner. This is very similar to the medicinal cannabis law in Canada, or what's been operating to some extent in California for the last decade."
