Re: Yet even with these privacy invasions
Even more, the underlying cause of the "drugs problem" is demand. Humans have always had a desire for recreational substances. All over the world, in all cultures, there has been some form of drug available and in widespread use. In the west it was mostly alcohol, Native Americans had tobacco, in South America they had the cocoa leaf... the list goes on. Now, these have spread from their native lands, some have been defined, so people have more choice.
While demand exists, someone will supply, legal or not. If the government ban it, criminals (or someone, who then becomes a criminal) will step in to fill the gap. A lot of the time this is large criminal organisations. So by banning the substance, you feed more money into the criminal organisations, which use that money for other criminal activities.
The war on drugs is doomed to failure on the grounds of basic human nature, and (IMHO) does more harm than good.
