Medical Marijuana is NOT legal in the state of California; contrary to popular opinion, it is still ILLEGAL. I only know this because I am a criminal defense and Medical Marijuana Business attorney. The law, instead, provides only a defense to certain marijuana related offenses (a limited immunity from prosecution) ^[1] — Preceding unsigned comment added by 107.217.74.25 ( talk) 08:28, 8 June 2016 (UTC) reply

(add your own items as needed)

• Scan through for copyediting, punctuation, phrasing, tone, etc.
• Is MMJ fully "legal" under CA law, or just an affirmative defense? (see complaint from lawyer further up this page)
• When are the first examples of drug use of cannabis in California? Was it pharmacy tinctures/hashish, or was it smoked cannabis?
• When did smoked cannabis arrive in California, and did it come from Mexico?
• Has California resumed growing industrial cannabis yet? If so, when did that resume?
• We skip entirely the history of how beatniks and hippies popularized cannabis.
• California's role in promoting sinsemilla
• Shifting of major cultivation from Mexico to California
• Information about environmental impacts within Cultivation section?
• Potential Irrigation section under Cultivation section?

Sorry if I'm doing this wrong or messing up formatting, this is my first time doing this! I've found a ton of peer-reviewed articles on cannabis irrigation practices in the Emerald Triangle as well as their impacts on water pollution and biodiversity in the area. I'm considering adding information to the cultivation section or adding a new section called "Irrigation." Let me know what you think! SarHasUCSC ( talk) 19:39, 15 April 2022 (UTC)SarHasUCSC reply

I've added mine, please add yours and we'll see what we can get done before the New Year. Goonsquad LCpl Mulvaney ( talk) 08:07, 25 December 2017 (UTC) reply

I've noticed the article doesn't cover anything about the evolution of medical cannabis in California leading up to the passage of Proposition 215 in 1996. See the section California (early and mid-1990s) on Medical cannabis in the United States to see exactly what I'm talking about. This is pretty important information not only for the history of cannabis in California but also the cannabis reform movement at the national level, as the passage of Proposition P (in San Francisco) set in motion a chain of events leading to California becoming the first state to legalize medical cannabis. I suppose the material could be copied pretty much word-for-word from Medical cannabis in the United States, but if someone wants to find some other way to finesse it into the article, go for it.

BTW, I originally came here today to recommend a good resource for this page after seeing the recent discussion on WikiProject Cannabis. It's a 368-page long thesis paper, so I don't know if anyone will have the time or motivation to look through it, but it has A LOT of good information about the history of cannabis reform in California that would be useful for expanding this article. I read through it this summer while working on Medical cannabis in the United States, but I don't really have time to look through it again and work on this article, unfortunately. Maybe someone will find it useful a week from now or a decade from though, so I will leave it right here, freely available to download in PDF form.-- Jamesy0627144 ( talk) 18:25, 25 December 2017 (UTC) reply

The pic at the top of the article is also problematic, as it gives the reader the impression that medical cannabis in California is basically a sham. Not to say that it doesn't have a place in the article though (as the article does discuss the "quasi-legality" issue), but I don't think it should be at the top. These operations will also soon become a relic of the past (once recreational becomes fully up and running), so for that reason also it should not remain at top. It would be nice if there was a pic of a California dispensary that could be used, but I searched wikimedia and couldn't find anything.-- Jamesy0627144 ( talk) 19:31, 12 February 2018 (UTC) reply

Contamination of legal and illegal cannabis products

• 16 Aug 2019: Illicit Cannabis Vape Carts Hospitalized 7 in California, Doctors Say. By David Downs, Leafly. From the end of the article (emphasis added): "David Downs directs news and lifestyle coverage as the California Bureau Chief for Leafly.com. He's written for WIRED, Rolling Stone and Billboard, and is the former cannabis editor of the San Francisco Chronicle, as well as the author of several cannabis books including 'Marijuana Harvest' by Ed Rosenthal and David Downs." From Leafly Wikipedia article: "Leafly is the largest cannabis website in the world, with over 15 million monthly visitors and 40 million page views across its website and mobile applications." From the article (emphasis added):

California leads legalization states in requiring all products sold at licensed stores to be tested for dozens of contaminants—most notably pesticides, residual solvents like hexane, and heavy metals like lead. But with untested products, said Wurzer, a wide variety of allergens, irritants, and toxins could lurk inside. After lab testing became mandatory in California in 2018, hundreds of products were flagged. To date, more than 5,169 batches have failed state lab testing for labeling or impurity standards. After inaccurate labeling, pesticides have been the biggest culprit. Lead has also popped up in cartridges.

Neem oil, or its active ingredient azadirachtin. The reader comments at the end of the following articles are especially informative.

• 9 Aug 2017: Could Cannabis Hyperemesis Syndrome Really Be Pesticide Poisoning? | PotGuide.com. From the article (emphasis added):

To control pests on cannabis plants, many home and industrial growers use neem oil, an organic oil excreted from neem (evergreen) trees to protect them from pest and mold infestation. ... Neem oil can be used as a pesticide/fungicide on cannabis plants, too, but only during the vegetative stage of growth. Once flowers start budding, all pesticide use should be ceased lest the product absorb into the flower which cannot be washed clean without washing away valuable trichomes, too.

25 Jan 2019: California Cannabis Labs Are Finding Toxic Metal in Vape Carts. Leafly. From the article:

All vape carts made for the licensed, adult-use market in California after Jan. 1, 2019 should be lab-tested and contain less than 0.5 ppm lead. Look for “manufactured on” dates on the label. If you want to inhale 100% lead-free vapor, you should abstain from using cartridges until carts with lead-free metal start hitting California shores later this winter.

19 Feb 2019: Cannabis Cartridges Have a Heavy Metal Problem & It Is Worse Than Reported. From the article (emphasis added):

Robinson and colleagues conducted a lot of research “on different materials that didn’t flake under heat cycling.” ... a product that doesn’t always vaporize and generally smolders or combusts the oil around the heating element, which can produce carcinogens and potentially other contaminants.

I checked several links, all which directed me to the intended site. I also checked several of the citations and did not find any plagiarized statements or close paraphrasing.

I noticed not all of the facts provided in the article are referenced. It is possible that the writer knew those facts and didn’t reference them as a result, but it would be a good idea to reference material regarding the facts which aren’t referenced, like when Cannabis was “decriminalized” for medical use and recreational use. Additionally, Cannabis has not been legalized, but it is no longer prosecuted for possession and several other circumstances which should be added to the article.

I1stephe ( talk) 19:27, 25 April 2022 (UTC)I1Stephe reply

I think the article could go more into depth about a couple of different things, for example it discusses growing, but doesn’t discuss the limit for how much an individual can grow. So, I think it would be a good idea to go through and check all the topics discussed and make sure they have been discussed thoroughly.

I1stephe ( talk) 19:27, 25 April 2022 (UTC)I1Stephe reply

I don’t think the article discusses very much about opposition to the legalization of Marijuana and why. It consistently discusses the efforts people have made to legalize it and the legal efforts made, but it doesn’t discuss efforts made against legalization.
