I would put the number much higher given their age.
Can anyone list a state or county where marijuana was decriminalized against the wishes of the majority in that area?
I actually agree with the banning of it's use in public areas, since people not partaking in this drug should not be exposed, no different than not needing to smell or inhale second hand cigarette smoke.
However, what people do on their private property, as consenting adults, is no one's business in regards to marijuana. If someone is going to pull this public health, environment or safety crap from their rear, then they should also accept it when the left use the same argument style to ban gas stoves, gasoline cars, ATVs, and guns... You can make ANYTHING into an environmental, public safety or health issue - ANYTHING.
There needs to be a direct correlation, a “provable causality,” and real damages (not dreamed up theoretic junk) for you to strip people of a freedom.
