The average price for a gram of legal recreational marijuana costs almost twice as much as the same amount from an illegal supplier.

Statistics Canada says between October 17th, legalization day, and December 31st, a gram of pot purchased through legal channels sold for nine-dollars and 70 cents on average, while black market cannabis sold for about six-dollars and 51 cents.

The agency also notes the average amount of non-medical cannabis purchased from an illegal supplier was more than double the quantity bought from government-run stores or websites, averaging at about 17.2 grams from illegal suppliers, compared with 8.3 grams from legal outlets.

Those who responded to StatsCannabis said they purchased an average of 4.7 grams when buying at a retail outlet and an average of 9.1 grams when purchasing via mail delivery.
