Marijuana is not a narcotic, in law or practical life. A light-bulb in the basement is not exactly a laboratory. A single plant weighing 115 grams is not worth $2,500 on the black market. Your figures suggest that marijuana is worth $21.73 a gram. That's an error of fourfold. That's like saying the Monday edition of The Star sells for $3 when in fact it sells for 75 cents (outside Metro). Roddy Heading Niagra-on-the-Lake
