What the heck is the rush on this?  

To legalize it to make it harder for young people to acquire the drug seems counterintuitive.  We increase the amount of the drug available and yet, somehow, teen use is going to drop?  This makes no sense.  Teens are going to see this as the government condoning drug use.

Criminals won't be cut out of the supply chain either as they will either continue to sell the drug to minors who can't get it legally and/or they will just redouble their efforts peddling the harder stuff like they have done in the US states that have gone the legalization route.

Driving while under the influence will skyrocket as it has in the US because people think they can't get caught and they are basically right.  We have no reliable way to do a roadside test on this stuff that will hold up in court.  It's hard enough to get an alcohol related offence prosecuted right now and we have breathalyzers.

This is all about "revenue generation" trumping public safety.
