Does alcohol use destroy society? Did Prohibition work? If we'd end the War on Drugs we'd save a lot of time, money, (not to mention we'd stop violating an individual's right to do with his/her bodies as he pleases). Drug use is not harmful. Drug abuse is. I know plenty of people who smoke weed occasionally and they're better off than my friends who get smashed on alcohol every weekend.
But drug use is against the law! You mean the laws intended to prevent drug use (gasp) aren't working?
Does drug prohibition build or maintain societies? Was America more civilized during the 19 years of alcohol prohibition than we are now? Are Muslim theocracies that are even less tolerant of drugs the we are more enlightened societies?
Drug use does not destroy society. Drug abuse might, but that's another discussion.
No, I'm not kidding. I've used many drugs and still do. I drink alcohol, used to smoke including grass when I was young. So have most of my friends and acquaintances and most of them are VERY productive members of society. Now the ABUSE of drugs, food, automobiles, tempers,etc., can and will destroy society or it's people. Sometimes it kills and destroys families. ALMOST anything in moderation is fine - and should be left to individual choice.
My motto is: GET THE GOVERNMENT OUT of my bedroom and my habits. The main purpose of the Federal Gov is to keep it's citizens safe and secure from Foreign or Domestic intrusion.
