It takes time. Pot should be managed in Canada the same way that beer is managed in Germany.
The link with psychosis and hydroponic pot is very real, the CBD is taken out loading up on THC. That's not what nature intended. CBD is effective for people living with multiple sclerosis and the buzz from the THC is euphoric. Another form, Nabilone works very well on cancer patients undergoing chemotherapy. Other forms of health benefits have not been entirely proven. The problem with hydroponic is that it's not a buzz, it's an onslaught.
This is entirely a new field, we'll be learning as we progress. Unfortunately Charles McVety is against it, if Scheer becomes PM, he'll make pot illegal again. All that valuable RD will go out th window.
