Marijuana is now the most valuable agricultural product in Canada, finishing ahead of wheat, cattle and timber, the Guardian reported Nov. 4.

According to Forbes magazine, marijuana cultivation is generating $7 billion in sales annually in British Columbia alone. Even higher revenues are expected over the coming years.

“Canadian dope, boosted by custom nutrients, high-intensity metal-halide lights, and 20 years of breeding, is five times as potent as what Americans smoked in the 1970s,” according to Forbes.

Forbes said the Canadian marijuana business has become strong because the growers are “not a small coterie of drug lords who could be decimated with a few well-targeted prosecutions, but an army of ordinary folks.”

Furthermore, relaxed marijuana laws in the country have resulted in increased confidence in the industry.
