As Canadian medical cannabis is becoming a real possibility, it’s worth noting that all the pot thousands of patients would require could be grown by a handful of farmer-ceutical workers on a few hectares of land.
The following rough calculations suggest that the entire legal medical marijuana farming proposal will not be a big deal, certainly much smaller in scale than many med-pot watchers may imagine.
Consider that one cannabis plant, occupying one square metre of soil, could yield at maturity 100 grams of excellent bud at 12% THC. Assume one patient requires three grams of bud for one day’s medicine in the form of three 1 gram joints (or six half gram joints, whatever) to receive 0.36 grams of THC daily.
Therefore one patient requires 1095 grams of bud per year ? the yield of about ten mature female cannabis plants that occupy ten square meters of cultivated land and produce 120 grams of THC per year. A year’s supply of medical pot for one person could be grown in a space about the size of one parking space for a Volkswagen.
One hectare of farmland (10,000 square metres or 2.7 acres) could produce enough marijuana to supply 1,000 patients with 3 grams of bud each day for one year. That’s a million grams of bud, rolled into a million, one gram joints, for a grand total of 120,000 grams (or 120 kilograms) of THC. From just a single hectare of soil ? the area of a small parking lot.
A single bonded farm could generate all the medical marijuana required to make medicine for many, many thousands
Certain considerations have been ignored in this simplified formula, such as many tons of semi-potent leaves and twigs left over. These residual cannabinoids could be expertly extracted and added to the stockpile.
If you recalculate with more generous consumption rates, or believe even higher yields of even stronger potency bud per metre are more accurate, go right ahead. The farmland required to produce medical pot for a lot of people is not going to turn out to be a very big operation in the final wash…
