From my understanding, at least in Canada, we’ve an increase in older people using and a decrease in younger people trying.
Essentially older people who may have used back in the day generally gave it up when they had kids and lost their plug. Now that it’s legal and available they are going back to it since its easier to get now then having to know some guy and go through that whole rigmarole. As for the younger crowd, dealers aren’t as common since most people just buy it from the store, or grow their own and they have other avenues to form addictions, like social media.
