I think the spirit is clear throughout the wording of the law: the age of use is 21. We created a MCB just like the ABC. I agree, after a full reading the exact phrase "regulated like alcohol" is not in the text. 

I'm just tired of everyone battling this. We were smart enough as a state to vote for this revenue generating, crime reducing, life saving measure and we have been utterly let down by our governing body who largely fight this at every turn.
