Re: "too mature to use the junk"

You may have meant "too old", not "too mature". 

Except, in Florida, 82% of seniors are in favor of legal pot - medicinally and recreationally.

Young stoners will do what young stoners have always done. And, it will still be illegal for them to do it. And, I'm pretty sure legal age for consumption will be part and parcel of the regulations. Despite your evident disapproval. 

One could get the impression you think it's going to be made mandatory ... sorta like same-sex marriage was.
