Let's see. Health: 1. Purity would be guaranteed, much as it is with acetaminophen and aspirin. Varying purity between batches of drugs is one of the leading causes of overdose. 2. Substances would be what they are marketed as. No more people dying because they took PMA that they thought was MDMA. 3. IV use could be made safer. No more bans on buying needles without prescriptions , as exist in some areas. Needle exchanges can be set up, they are also banned some places. 4. Serious drug health education can begin, drugs can come with harm reduction sheets on how to minimize the damages. 5. Drug combinations can be created that reduce the risk of damage from the drug use. Recreational drugs can be mixed with neuroprotective drugs to inhibit brain damage. 6. The new found purity of drugs means they wont be cut with dangerous substances like cocaine currently tends to be cut with levamisole leading to people having flesh rotting away from their faces and arms where they inject it at 7. Actual research on the harmful effects of drugs can be carried out. Research chemicals can actually be professionally analyzed with animal experiments and such carried out, in the hopes of preventing people from using inherently highly dangerous drugs. 8. Professional quality control during manufacturing means that we will avoid things like MPPP/MPTP happening again 9. Prepackaging of drugs means that you will get pre measured doses in the correct units, no more stupid kids trying to eyeball drugs that are active at 1 MG Other: 1. People will no longer need to go to dangerous areas to purchase drugs (some do!) 2. The Cartels will immediately go out of business, saving tens of thousands of lives every single year 3. Drug oriented gangs will have their profits majorly slashed, leading to an over all reduction in crime 4. Not to mention there will no longer be drug related gang wars, saving thousands of lives a year including the lives of innocents caught in the cross fire 5. Not to mention kids wont be caught with drugs and sent to prisons where they turn into hardened career criminals 6. Not to mention the prison population will be cut in half almost immediately, leading to a major upswing in the economy not only from all of the new productive citizens but also from our lack of need to fund a massive prison industry (but boo fucking hoo some dumb fuck DEA agent will lose his job! IMO they will be lucky to not lose their lives by the time people wake up to this farce) 7. Not to mention trillions of dollars a year spent fighting the war on drugs can be spent on more important things, like rehabilitation for the people who actually need it (hint: not everyone who uses drugs is a fucking addict!), like research into drug safety and all kinds of other good productive things that don't involve ENSLAVING THE INNOCENT I am sure the list goes on and on but I just wanted to get it started, feel free to add the many things I missed.
