Bugs, Mold, and Excrement: Welcome to the Brave New World of California Cannabis

On Nov 16, 2017, California officials expelled a new set of regulations for cannabis manufacturing, testing, and growing. In many respects, these updates are a poignant alleviation to the initial breeze regulations, however, some major problems remain. 

Two critical issues associate to regulations on mold and unfamiliar filth, which are absurdly loose. And distinct the initial proposal, no matter as to the motive behind the new regulations has been released.

Safety requirements


Allowable boundary for contaminants including pesticides, solvents, and microbes are described in sections 5718-5723 of the new regulations. These regulations have bound a major issue in the initial breeze where two opposite units were confused – tools per million by weight (µg/g) and tools per million by volume. Now well-off and bomb boundary are given in µg/g.

Other significant changes:

  • Solvent boundary are mostly improved. Certain category 2 solvents have been banned, as Project CBD had formerly suggested.
  • Pesticide boundary have swung from being very despotic to being overly lax. The environmental concerns associated to bomb overuse seem some-more cryptic than the health effects for consumers.
  • Many bomb reserve boundary are still formed on regulations for tobacco, which is entirely inappropriate.
  • Required tests for microbial decay are minimal.
  • Limits on mold – one of the many common contaminants of cannabis – are scarcely nonexistent. A product is deemed to pass regulations if reduction than 1/4th of it is covered in mold.

Solvents - §5718

Solvents are broken into two categories for the purpose of regulations. Category 1 solvents are banned and are not slight at any detectable levels in cannabis products. Category 2 solvents are allowed up to set movement boundary that count on the well-off in doubt and possibly the product is inhaled or not. Action boundary for non-inhaled products were suitable in the initial breeze offer and have not changed.

The initial due regulations allowed for the use of frequency dangerous solvents, including benzene, which Project CBD suggested be banned from use in cannabis manufacturing. We also suggested that regulators consider banning “class 2” solvents such as chloroform, given they are nonessential for producing many kinds of cannabis extracts.1 The new regulations now anathema the use of benzene and some category 2 solvents like chloroform, but concede other category 2 solvents, including hexane. (Hexane is frequency used to remove oil from cannabis, but is infrequently used to purify the oil of pesticides or other adulterants.) Although Project CBD hopes that cannabis manufacturers equivocate using hexane to remove or purify oil, we trust these regulations are appropriate.

Each slight well-off has a extent excusable thoroughness in inhaled cannabis products (e.g. vape cartridges). In the initial breeze proposal, these boundary were formed on reserve information from California’s Occupational Health and Safety Administration (OSHA), nonetheless the boundary were improperly distributed due to difficulty with units. (“Parts per million” can have mixed meanings, as mentioned above. See the previous Project CBD statement for some-more detail.) The new boundary are quite difficult for some category 2 solvents and are overly kindly for ethanol residues.2   On the whole, the new boundary are sensible.

Pesticides - §5719

Similar to solvents, pesticides are broken into banned pesticides, which are not allowed at any detectable concentration, and allowed pesticides. The movement boundary for accessible pesticides count on possibly the product is inhaled or not.

The regulations were expelled with only 5 days for open comments – including the weekend – and were not accompanied by any matter of reasons explaining how new reserve boundary were determined. As such, Project CBD’s comments on the new bomb regulations indicate out intensity problems but indispensably suggesting how these issues could be bound or their extent.

In the new regulations, the list of banned pesticides has shrunk dramatically, from 42 to 21. One of these now-allowed pesticides is a neonicotinoid (acetamiprid) and 4 others have “high strident toxicity” to humans, according to the initial matter of reasons (bifenthrin, cyfluthrin, naled, and abamectin). Most of the rest of the now-allowed pesticides were banned in the strange offer due to environmental concerns, including myclobutanil (often sold Eagle-20).

The initial set of breeze regulations on pesticides were very despotic in some regards. The extent of showing (LOD) – which is the lowest thoroughness of a devalue that can be rescued reliably – was arbitrarily set at 0.01 – 0.02 µg/g. This is reduce than the actual LOD of pesticides in cannabis for many labs. This has changed – now labs will establish their LODs scientifically and list these LODs on lab reports.3 This is an important fix.

To reiterate: given no matter of reasons has been released, we do not know the motive behind the boundary for pesticides on non-inhaled products. But we can contend with some certainty that it is not formed on the relations reserve of these pesticides.

Safe boundary for bomb ingestion are given as the excusable daily intake (ADI) or strident anxiety sip (ARfD), and are reported by the World Health Organization. The ADI indicates a turn of bomb ingestion that is deliberate protected for ongoing daily use, which creates clarity for food or medicine. Converting the ADIinto a extent for a bomb in cannabis products depends on the volume of product that is consumed. If the boundary were formed on protected ingestion limits, the ratio of the ADI to the movement extent would be constant. In the stream proposal, this ratio varies from 2.5 to 750, a 300-fold difference. Pesticides like trifloxystrobin, bifenazate, and permethrin have very high movement boundary compared to their toxicity when ingested.

It appears that the boundary were not formed on environmental concerns either: Of the 7 slightest regulated pesticides (i.e. those with the top excusable limits), 5 were creatively banned due to intensity belligerent water contamination.

For inhaled products, the boundary still seem to be formed on tobacco, as described in the initial matter of reasons. This may be given very little is famous about the effects of heating or blazing pesticides (an information opening attributable to lobbying from the tobacco industry). Some pesticides will, in fact, turn safer when burned, while many others will mangle down to much some-more toxic compounds.

The EPA has formerly settled that it need not study the health effects of blazing pesticides at concentrations next 0.1 µg/g in cigarettes given those people are already smoking tobacco. After all, nicotine is the bomb on which neonicotinoids are based.

It may be loyal that inhaling reduction than 0.1 µg/g of many pesticides is safe. But regulations need to be formed on systematic data. If reserve information on blazing and inhaling pesticides is not available, then the law should embody supplies to be updated as new data emerges.

The outcomes of the tobacco industry’s fight against scholarship should never be used as the basement of reserve regulations for another industry. Tobacco is the heading means of preventable deaths in the United States, killing roughly half a million people every year. This is precisely given the tobacco attention lobbied to safeguard that systematic information on health and reserve was not used to surprise laws or regulations. That should not be the starting indicate for any aspect of the rising cannabis industry.

Foreign element - §5722

The unfamiliar element testing, described in §5722, is over the pale. §5722(e) states that:

A representation shall be deemed to have upheld the unfamiliar element contrast if the participation of unfamiliar element does not exceed:
(1) 1/4 of the sum representation area covered by sand, soil, cinders, or dirt;
(2) 1/4 of the sum representation area covered by mold;
(3) 1 insect fragment, 1 rodent hair, or 1 count mammalian excreta per 3.0 grams; or
(4) 1/4 of the sum representation area covered by an 
imbeddedforeign material.

A tiny piece of chocolate weighs about 3.5 grams. 

Under the new regulations, a 16-piece chocolate bar would be deliberate excusable if 4 pieces were covered in dirt, 4 some-more were covered in mold, and any of the 16 pieces had an insect partial or rodent poop on it.

Microbes - §5720

There is an rare change in regulations on microbial contamination. Cannabis is not compulsory to be free of mold nor are labs compulsory to test for mold. The only extent on mold is given in (2) of the unfamiliar pollution territory quoted above, which states that up to 1/4th of a product can be covered in mold.

Under the new proposal, products only need to be screened for 3 microbes: pathogenic E. coli, salmonella, and in the case of inhaled products, aspergillus. Since no matter of reasons were expelled with the regulations, it is not transparent why 

California is so messy with microbes. Giving regulators the advantage of the doubt, it may be that they are trying not to shorten the use of profitable microbes, an organic flourishing use that uses non-harmful microbes as an choice to pesticides. But mold is one of the many common contaminants on cannabis. It is positively essential to test for mold on cannabis, quite when grown indoors.

Phase in of reserve contrast - §5715

The regulations have been expelled with just over a month before they will be implemented. To palliate the weight on labs, contrast will be phased in over the march of a year. This gives labs time to rise and countenance methods for any kind of product and any kind of test.

On Jan 1, 2018, all authorised products must be tested for cannabinoids, allowed solvents, banned pesticides, microbes, and product homogeneity.  On Jul 1, 2018, 3 additional tests will be required: banned solvents, allowed pesticides, and unfamiliar material. On Jan 1, 2019, complicated metals, mycotoxins, and presumably terpenes will also be tested before sales.

Project CBD hopes that terpene contrast will turn some-more commonplace, as this will help to irradiate the healing properties of these critical plant components.

Other regulations

There are many critical aspects of the new regulations that residence issues over consumer safety. Here are some key points:

  • There is effectively no longer a extent on the distance of grows. Each permit allows a organisation or particular to grow up to one hactare of cannabis, but there is no extent on the series of licenses a organisation can get. Project CBD shares the concerns of farmers who are worried that this will concede large-scale cultivation to pull out smaller, some-more tolerable gardens. Privileging rich out-of-state investors and big players at the responsibility of family farmers is bad policy with diseased long-term implications for California’s economy and environment.
  • Law coercion are allowed to duplicate the materials, records, and books of any employee of any protected cannabis business. See §5800(a)(4).
  • Recreational products can’t be given divided for free. Medical patients can be given free products by a merciful caring program, but this program must be run by a internal jurisdiction, not a cannabis business. Moreover, only protected retailers (e.g. a authorised dispensary), not product manufacturers, can yield free products to patients. See §5411.
  • Medical patients under the age of 18 can't be served at a dispensary. Their caregiver must buy product for them. See §5400(b).
  • Edibles are compulsory to enclose no some-more than 10 mg THC per portion and 100 mg THC per package. Other products must enclose reduction than 1000 mg or 2000 mg THC per package, depending if the product is recreational or medical. See §40306.
  • Edibles can't enclose any other addictive substances, including caffeine, alcohol, and nicotine. Exceptions are done for cannabis chocolate, tea, and coffee. See §40300(b).
  • Labs are compulsory to be approved by one of two groups (the International Standard Oganization or International Electrotechnical Commission). This will help safeguard the correctness and coherence of lab tests, which has been cryptic in the past.
  • It is now much easier to get a permit to do ethanol extraction, given it is deliberate a “nonvolatile solvent.” See the clarification of “nonvolatile solvent” in §40100.

1 Solvents are personal into one of 3 groups by the FDA. Class 1 solvents like benzene are possibly very poisonous or environmental hazards and should be avoided in production if at all possible. Class 3 solvents like ethanol and butane are sincerely protected at low concentrations. Class 2 solvents like chloroform and dichloromethane are reduction dangerous than category 1 solvents, but should be avoided if the use of a category 3 well-off is possible.
2 This is not to contend that the excusable boundary are wrong. But compared to reserve information from OSHA, boundary are disproportionately messy for ethanol and despotic for category 2 solvents.
3 A second series to be listed on lab reports is the extent of quantification (LOQ), which is at slightest as vast as the LOD. The LOQ is the extent at which the thoroughness of a chemical can be accurately discerned. The operation between the LOD and the LOQ is the operation of concentrations where a test can show that a chemical is present, but can't establish its accurate concentration.
4 Products with mixed servings (e.g. a chocolate bar) will be tested every 6 months to safeguard that every piece has roughly the same volume of cannabinoids in it. Specifically, the relations customary flaw must be reduction than 10% of the meant volume of each cannabinoid.
