- Subject: MOLDY MJ...The straight dope (2d attempt!)
-
- Recently, the subject of moldy pot has arisen and unfortunately, there is some
- erroneous information circulating. Someone has even suggested burying your
- stash to make it more potent! Reading this article should point out the
- dangers of that stunt, as well as other methods of storing pot that can be
- hazardous to your health and even fatal.
-
- The following article was published in the May 1993 High Times and although
- I have no permission to copy it, here it is. Read it carefully as your life
- may well depend on it.
-
- N.B.: Underscores, e.g. "_Lasioderma_" indicate italics.

- "HOW TO PRESERVE POT POTENCY...by stopping bugs and fungi before they damage
- your weed," by The Bush Doctor
- //////////////////////////////////////////////////////////////////////////////
-
- Growers taking time to harvest a healthy cornucpoia of cannabis must also
- carefully watch over their cut crops. In addition to two-legged thieves,
- myriad bacteria, molds and insects have been known to rip-off your stash while
- curing, drying, or in the fridge. Avoiding these ubiquitous threats is nearly
- impossible, but there is a way to lessen their impact. The key is being able
- to manipulate storage conditions.
-
- A variety of bacteria grow on damp marijuana. Many are deadly. Researchers
- have found _Klebsiella pneumoniae_, _Enterobacter cloacae_ and _Streptococcus_
- (group D) growing in government-supplied reefer. _Salmonella muenchen_ was
- found in marijuana growing across the Midwest. (Let someone else roll the
- joints. I don't lick rolling papers anymore!) Under anaerobic conditions
- (i.e., damp marijuana stored in airtight containers), _Clostridium_ species
- will rot pot; these are the famous boutlism bacteria.
-
- In addition, a number of bacteria-like Actinomycetes have been identified in
- confiscated ganja, including _Thermoactinomyces candidus_, _T. vulgaris_, and
- _Micropolyspora faeni._ These bugs cause allergic reactions (sometimes
- severe), as well as "Farmer's lung" disease.
-
- Insects in pot are less intense. Growroom critters, such as aphids and spider
- mites, rarely damage marijuana after harvest. Smith & Olson (a list of
- references appears at the end of this article) identified five beetle species
- from confiscated Mexican weed in San Francisco. They completed this study at
- the request of the DEA agents, whose offices were overrun by the pests. The
- predominant species, _Tribolium confusum_ (confused flour beetle), attacks only
- seeds, not marijuana proper. Two other beetles cited in the study,
- _Adistermia watsoni_ and _Microgramme arga_, are fungus feeders (the marijuana
- was moldy). Thankfully, the researchers found no cannabis equivalent to
- _Lasioderma serricone_, the tobacco cigarette beetle. Otherwise some whacked
- government lab would be growing the bugs en masse to spread across the
- continent.
-
- Fungi destroy more bud than bacteria and insects combined. Bacteria in
- marijuana may be more dangerous to humans, but they are rare. Molds are
- common, and can be nasty: Ramirez reports four policeman developing pulmonary
- histoplasmosis after pulling up a 5,000-square-meter plot of marijuana in
- Puerto Rico. Some fungi won't rot pot, but they will put you in the hospital.
-
- Many fungi causing disease in plants die off after their host is harvested.
- Exceptions include _Botrytis cinerea_ (the cause of gray mold) and _Alternaria
- alternata_ (brown blight). After harvest, your competition becomes
- _Aspergillus_, _Penicillium_, _Rhizopus_, and _Mucor_, the baddest actors on
- the planet. Each genus causes disease under different conditions:
-
- Ubiquitous _Aspergillus_ grows on anything from rocket fuel to astronauts. The
- genus is millions of years old; while _Home sapiens_ may come and go,
- _Aspergillus_ will remain. Westendorp first found an _Aspergillus_ species
- attacking _Cannabis_ in 1854. More recently, Margolis & Clorfene describe a
- mold that _increases_ potency in marijuana. Their "black weblike fungus"
- sounds like an _Aspergillus_ species. _What_ species, I'd like to know....
-
- Schwartz scraped _Aspergillus niger_ from the skull of a marijuana smoker
- experiencing sinus headaches. I frequently encounter _A. niger_ growing in
- ganja stored at room temperature. It does _not_ increase potency. Kagen also
- reports _A. niger_ growing in moldy marijuana, along with two _even nastier_
- Aspergilli: _A. fumigatus_ and _A. flavus._
-
- Chusid et al. blame _A. fumigatus_ for causing near-fatal pneumonitis in a
- 17-year-old. They note the patient buried his marijuana underground for
- "aging." No doubt the patient was looking for Margolis & Clorfene's fungus,
- but _A. fumigatus_ found him instead. _A. flavus_, on the other hand, kills
- slowly. It oozes carcinogenic metabolites called aflatoxins. Llewellyn &
- O'Rear found aflatoxins contaminating Virginian marijuana.
-
- _Aspergillus_ species grow better in warmer climates, _Penicillium_ in cooler
- climates. Refrigerator storage encourages _Penicillium_ infestation. Kagen et
- al. isolated _Penicillium_ from marijuana cigarettes. Babu et al. identified
- _P. chrysogenum_ attacking marijuana. (_P. chrysogenum_ occurs abundantly in
- nature, and was Alexander Fleming's source of penicillin.) I isolated _P.
- italicum_ from marijuana stored with an orange peel at 0 degrees Centigrade.
- Adding peels to pot imparts a "pleasant bouquet" (Frank & Rosenthal). In my
- case, the peel imparted a nidus of infection. _P italicum_, the "blue citrus
- mold," is notorious for its ability to spread by contact (i.e., "one bad apple
- spoils the whole bunch").
-
- Five _Mucor_ species have been described on _Cannabis._ Members of this genus
- grow fast and die young. One of them, _M. hiemalis_, regrettably
- bioconcentrates (and cannot metabolize) the herbicide paraquat from tainted
- substrates (Domsch et al.). _Mucor's_ first cousin, _Rhizopus,_ occurs in
- soil, ripe foodstuffs, and occasionally on people (especially diabetics).
- Grebeniuk isolated _R. stolonifer_ from hemp stems. In an inoculation
- experiment, I quickly rotted some damp marijuana with a colony of _R.
- stolonifer_ found growing on bread.
-
- DIAGNOSIS
- Rotting marijuana produces a spectrum of odors, from stale to musty to moldy.
- _P. italicum_ perfumes a lavender bouquet, while _A. flavus_ smells like a
- locker room. _Clostridium_ bacteria stink like carrion.
-
- Infested marijuana often darkens in color and becomes crumbly. Anaerobic
- bacteria turn marijuana into brown slime. Marijuana undergoing rapid decay may
- feel warm to touch. (At this stage your stash is ready for the compost heap.)
- Tufts of fungi are often visible in mold material. In marijuana stored in
- darkness, strands look white to light grey. Exposed to light, storage molds
- spawn millions of colored spores in velvet clumps. A slight tap sends these
- spores into great billowing clouds. Generally, _Rhizopus_ and _Mucor_ produce
- grey-black spores; _Penicillium_ species are light blue-green; and
- _Aspergillus_ species are dark green-black.
-
- To check for aflatoxins, inspect your stash under a black light (in medicalese,
- a "Wood's Lamp"). Material contaminated with aflatoxin-producing _A. flavus_
- will fluoresce to a green hue under ultraviolet light.
-
- To screen for insects, simply shake samples in a No. 10 steel sieve. Of
- course, not all bugs found in marijuana cause damage. Some are simply
- "innocent bystanders" caught during harvesting and die right away. Live (and
- chewing) insects are more suspicious. A hand lens is helpful for I.D.
-
- CONTROL
- Avoid damaging plants before they completely dry (even while they are in the
- ground and growing). Wounded tissues release exudates on which fungi feed and
- establish a foothold. Lucas says diseased and nutrient-deficient leaves (as
- well as old yellow leaves) produce more exudates than healthy leaves. Expect
- more mold problems in poorly grown plants.
-
- The secret to stopping bacteria and mildew is moisture control. Even grey mold
- dies if plants are carefully and quickly dried. Oven-cured pot rots less than
- air or sweat-cured crops. Sweat-cured _Cannabis_ (remember '70's Colombian?)
- maintains a "tradition" of _Aspergillus_ contamination.
-
- The oven-drying method inevitably leads to a harsh product. So most people
- air-dry by suspending plants upside down with enough space for circulation.
- Drying rooms should be cool and dry, preferably in uninterrupted darkness.
- (Most storage fungi require light to sporulate and spread.)
-
- Living cannabis plants are about 80% water. Perfectly dried marijuana contains
- about 10%-15% water or moisture content (MC). Material below 10% MC becomes
- too brittle and disintegrates. Fungi cannot grow below 15% MC. Unfortunately,
- many growers market their crop _above_ 15% MC. Cannabis, like corn flakes, is
- sold by weight, not volume. Tobacco farmers also allow thier product to gain
- weight by reabsorbing moisture before sale. They term this risky business
- "coming into order." Recently purchased products should be redried. Freezer
- storage will not protect damp pot. Placing lemon or orange peels in stored
- marjiuana is discouraged, as they raise the MC above 15%. Dipping
- _Penicillium_-infested plants in a solution of baking powder will inhibit these
- acid-loving fungi but the product must be rapidly redried.
-
- Maintaining stored marijuana at 10%-15% MC also discourages insects.
- Insecticides have no application in stored marijuana. Their residue pose a
- danger to customers. Also, water-based sprays will kill bugs but trigger a
- fungus infection by raising the MC. Fumigants (gas, not sprays or aerosols)
- contain no liquid, thus they do not trigger mold infestations. But they leave
- residues in air pockets of fumigated material. Big buds are full of air
- pockets. Poisons are very useful for disinfecting drying rooms, but only
- _after_ the crop has been cleared out.
-
- Low temperatures will "freeze" an insect infestation. However, with rewarming,
- many bugs continue their destruction. Another drawback to freezing above-15%
- MC marijuana involves the aforementioned exacerbation of _Penicillium._
- Heating marijuana in a 66-93 degree Centigrade oven for 10 minutes will kill
- most pests. This also dries out the product--again, the cornerstone of
- control. Marijuana should not be heated longer than 10 minutes or 93 degrees
- Centigrade to prevent THC oxidation.
-
- CONSUMER CAVEATS
- Immunosuppressed individuals and asthmatics should never be exposed to molds,
- especially _Aspergillus._ People using medical marijuana should take extra
- precautions:
-
- Ungerlerder et al. sterilized marijuana with ethylene oxide, reporting no loss
- of THC from fumigation. These researchers also irradiated their dope with
- high-dose Cobalt 60 (15,000 to 20,000 Gray Units!) with no loss of THC. _This
- method is not recommended for novices._
-
- Moody et al. evaluated waterpipes for smoking _Aspergillus_-contaminated
- marijuana. Unfortunately, they found only a 15% reduction in transmission of
- fungal spores.
-
- In Chicago, goofy dudes spray their marijuana with formaldehyde. This kills
- insects and fungi, but at a price. The treated weed, known as AMP, causes
- anoxia and psychomotor retardation when smoked (Spector). According to
- _Newsweek_ (Jan. 20, 1986), a few ill-intentioned dealers dipped marijuana in
- rat poison or insecticides like Black Flag or Raid. They called this product
- "WAC." Indeed. Have a nice day.
