Good Morning Cap'n
As someone who has sold drugs legally for many years I can tell you, if people could get their hands on all the drugs they wanted, society would be in a gigantic mess in short order. Hard core use of narcotics and hallucinogens might not go up but the number of people abusing anti-anxiety drugs and muscle relaxants (which don't work anyway) would increase rapidly. There would also be widespread use of antibiotics for trival viral infections which would increase drug resistance in bacteria and affect us all. Without the present restrictions related to prescriptions drugs, drug prices would decrease (this happens every time a prescription drug goes OTC). On he surface this sounds like a good thing but it would severely restrict the dollars available for research. Unless you think we already have all the drugs we need, you can see that this is a bad thing.
The bottom line is that the average person does not have the training and knowledge needed to determine what drugs he needs. The government is doing you a service by limiting your access to drugs, both therapeutic and recreational.
I am not suggesting that there be no restrictions. I am suggesting #1 that the federal government has no Constitutional authority to do so and that any restrictions remain at the state level.
Relative to "contrrolled dangerous substances" who is in control of them, but, the illegal cartels, gangs, smugglers, and the mob? The legal drugs are controlled by the government and I agree there should be controls as to the quality and who can use them so we can know for sure that what we put into our body is of a quality that is safe and the content is accurate. As it is now, any ad hock chemist can make something in his bath tub or basement lab which could contain contaminates or other impurities and we'll never know for sure that the dosages are accurate like we can with the legal drugs. That is another reason to legalize everything.
I put no weight in the argument that drug abuse would increase if we did that simply because those who want drugs now can get them and those who don't and know where to get them do n't use them by choice. If we legalized say LSD or Herion or Pot or whatever it's unrealistic to think people would all of a sudden say "oh herion is now legal I think I'll start using Herion".
In fact because of the illegal status of certain drugs that are in demand it throws the entire merket into the black market which is the cause of most of the vio0lent crimes associated with drugs along with the over doses and deaths due to impurities that dealers put into the drugs to increase their profit margin.
Also, unscrupulous drug dealers and gangs think nothing of selling drugs to anyone including our kids while a legal outlet would lose his entire livlihood if he made that mistake. So legalization would actually reduce the accessability to our children especially if we increased the jail time associated with selling drugs to minors in the event of legalization.
So on one hand I advocate legalization of everything but on the other I also advocate say a 20-30 year sentence for selling drugs to minors. I also advocate increasing the penality for other harm that one does to another either while high on drugs or alcohol or in the procurement of drugs. If a violent crime is committed after legalization the penality should be severe because that person is a violent preditor. But, if a person ingests a substance he is harming himself and in my opinion there is no room for the government to protect us from harm that we do to ourselves otherwise they will start to pass laws trying to protect us from everything and anything. Oh wait. They already do that.
