Uhhhhhhhhhhh.......isn't that what the decriminalization crowd is yelling for in this country?
Lying is not friendly, fwtw.
Yes, there are standards of behavior -- one can't tolerate public intoxication or semi-intoxication of those operating dangerous equipment. Nor can a society ignore the dangers of addictive drugs in times and places a culture is more prone to addiction.
All drugs should be legal, some regulated to create a modest barrier to use -- as we do today with tobacco and alcohol, or drugs that require purchase at a pharmacy with the transfer professional hand to adult hand. Only a few should be extremely restricted for and only for extreme danger to the public -- and that depends on time and place.
In a truly free nation NO item should be wholly banned for any properly responsible adult can take upon himself or herself the duty to hold and use a thing wisely, and indeed at some time and place he or she may have to so use it for some great meritorious purpose.
Do you thing Our G0d placed ANYTHING on this Earth so is so dangerous that no man might somehow use it for the good.
No! Everything has its purpose, therefore let people be able to possess and investigate uses and learn and discover proper uses. Why hobble humanity?
