       | Despite the lecture I've gotten from every stoner on this, I've
       | never been convinced by people claiming that weed doesn't have
       | side effects. It always seemed like it would make my friends'

       | weed exacerbated things. [2]

       | Obviously this isn't a study, just vibes on my end, so it can

       | 
       | [1] I still think it should be legal since I think enforcing it
       | is worse than doing it, but I think it'll always make me
       | uncomfortable
       | 
       | [2] I was always terrified of doing any illegal drugs because I
       | was always afraid that drug dealers would cut it with something
       | horrible, so I to this day have never done any drugs that weren't
       | federally legal.

             | We don't need to go even that far. Upwards of 50% of people

             | emotionally self-regulating with _coffee_. 13% of the

             | This is not to demonize any of it - just to point out that

             | substances in a ritual of emotional self-regulation. The

             | but they're so deeply embedded in our cultures, that we

           | The material used in vaporizers is typically from
           | concentrated extracts. This is another product born out of
           | the long standing legal status of the flower. The real
           | question is, are users consuming _more_ when they vape as
           | opposed to other methods, or is this simply a more efficient
           | delivery mechanism for them?

           | > So the industry does this on purpose out of greed
           | 
           | You're ignoring edibles entirely. These products really
           | didn't exist before legalization. A large segment of these
           | products are much lower dose than the other specialty
           | products and often have reduced THC in favor of higher CBD,
           | CBG or CBN.

           | 
           | This single minded focus on potency of product and not on the
           | impact of users is unusual. Why have you made this such a
           | focus?
