I hail from the North Island but have lived my life in British Columbia, Canada. "How's it goin" from the other side of the Pacific? Haven't been back home since I was a teen, but will make it some day, if this global lockdown ever ends and freedom returns to Earth.
I actually did a post a couple years ago, warning New Zealand NOT to legalize cannabis. The reason being that I was here at ground zero in Canada when it was being legalized. It's all a big scam, to continue prohibition, and all the evils you mentioned (nasty weed, gangs, prison, etc).
Indeed we do get bud grown with all sorts of stuff added. People don't mind, or they consider it "organic". I'm of the opinion that NOTHING should be added to cannabis. Like nothing. Worm poo is packed with plenty of all the right kinds of nutrients. So are other natural clean organic sources. We don't need to add nutrients, or hormones, or sprays, or fungicides. That stuff is what kills people.
I've done maybe 100 posts on this topic, so I won't bore you too much more about it :P
If you want my take on "legalization", please check out Legalization is a LIE if you have 45 minutes sometime.
