Anything grown on a large scale is subject to this. I do not consume cannabis myself out of personal preference. I live in Colorado and have been pro-legalization my entire life. I did try it when I was around 16 (I am 49 now) and my parents were hippies. I chose not to use any drugs, or alcohol after I was 16. I mention this just so it is clear what I am stating is not because of my desire for the product. This stuff will grow almost anywhere. It can grow in very limited conditions, however these huge grow houses are producing it far faster in all seasons and that would require a lot of energy. This is true of growing almost anything at such a scale.
So that pretty green marijuana plant isn't (((Green))) but a huge power hog?
Then energy companies force decent people to install dangerous smart meters
