Personally, I think it would be a good thing to decriminalise, I think it'd be even better to fully legalise, then the govt could tax and control it and use it as another revenue stream.
Yup.
If we legalized all drugs, then the drugs will become virtually worthless, and smuggling will no longer be necessary. This will reduce drug-related violence between rivalling dealers to almost zero, and it will very likely put some criminal, aswell as terrorist organisations out of business.
If the drugs are distributed by an apothecary or drugstore then the distributors can ensure quality, which means that the drugs will be pure, and be less of a hazard to the health of the people who use drugs. Information concerning health can be provided with the products aswell. Addicted customers can be monitored and registered, which means the distributor can decrease their dose step by step. People who use drugs will be less likely to get violent, end up homeless, and will no longer have to steal or even prostitute themselves for their shots. People who shoot won't have to share their needles anymore, which will reduce the spread of HIV and a variety of other diseases. Oh, and don't forget about the age limit!
If taxes are paid over all these drugs legally, then this will mean billions of extra income for the government. It will also mean that less tax money will be wasted on the war on drugs, and it will probably save a lot of lives of a lot of Police Officers, which in turn, will be able to focus on other violent crimes, although I'm convinced that the crime rates will drop by atleast 50% if all the crime that's involved with drugs will cease to exist.
And last but not least; Doing drugs will no longer be vieuwed as something illegal, so to a lot of young and rebellious people who are seeking the thrills and the kicks of doing something that's obviously not allowed, it might not appeal that much, or even seem adventurous anymore.
Oh, and to all the people who oppose legalization; People who want to use drugs will use it anyway. By opposing legalization, you're actually helping the criminals to make money, you're keeping all the dealers on the streets, and since the quality of their drugs is really poor, some drugs might even be deadly in the smallest dose.
