How do you spell marijuana? 

For most people, it isn't a debate. However, the Government of Canada sometimes spells the word with an "h" Marihuana. 

One website, Canada.com, reported Health Canada provided this official explanation:

"The common way to spell marijuana is with a “j” – however, the legal name and the way it is used under the program is with an “h”.  As a result, you will often see marijuana spelled two ways from Health Canada:

1)When referring to it in general terms “j”

2)When referring to the Program (Marihuana for Medical Purposes Regulation).
