Legalization of Cannabis, unexpected effects

Incidents of cannabis poisoning in the province of Quebec have more than tripled since marijuana was legalized for recreational use, according to the poison center, who filed a report with the public health department. It announced 89 recorded cases of marijuana poisoning between October and December of 2018, compared to 25 cases in the same time frame the previous year, according to CBC.
The reason behind the rise in marijuana poisoning is unclear at this time, but Maude Saint-Onge, director of the Poison Control Center, has a few theories. “Right now, it’s hard to distinguish whether there is more exposure, more cases of over-intoxication, or simply more people calling because they feel more comfortable now that it’s legal,” she said.

We as citizens are left wondering where the benefits are from the taxation of this legalized recreational drug?  Do Canadians gain any benefit from this?  Are we seeing any reduction in the illegal sourced drugs?  Any improvements to our infrastructure with the raised revenues?  Another campaign promise from the Prime Minister with no results?  Just more system resources being utilized to deal with the lack of supply, poisoning increases, and call center agents bearing the brunt of the aggravation.
