You can walk into a dispensary here and choose your levels and mix of THC and CBD - want 20%+ THC for an intense high? Maybe 15% CBD with no THC for almost no psychoactive high but a focus on pain relief / relaxing? All that and everything in between is available.
As research into all the other cannabinoids increases I expect to see their breakdowns included on labels as well.
And that's where the analogy to alcohol breaks down - there's typically just one active ingredient in beer but dozens in pot. And the different strains can deliver various ratios of the cannabinoids to create very different effects.
Bottom line is that I could easily see how if you only ever experienced illegal pot i.e. no choice and low quality I think you are likely to hold a different view on it than if you'd experienced the variety and nuance of legal pot.
