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.
