When we were carrying out our study on the decriminalization of marijuana—which you may recall—the Americans were of the opinion that one plant equalled 100 grams. As a result, according to the American system, it would be approximately 30 plants. I had done some research on the Internet. I read there that a single plant could grow to up to 375 grams over a two- to three-month period, if everything went well.
