I think it's a very good step! It looks like south america will lead the world to a healthier drug policy.
Indeed, some of these drugs are very dangerous and addictive, and I personally think it would be great if cocaine, methamphetamine and heroin disappear from the earth forever. The problem is that this will not happen. Where there is demand, there will be supply. Look at the prohibition, did people stop drinking? No, the market went into criminal hands.
There are of course other examples, which makes the debate more complicated. When heroin was made illegal (it used to be cough medicine), it's use declined. This was because by making it illegal people were given a signal that this stuff is bad for you.
However, usually making a substance illegal simply doesn't effect the number of users, and it has many adverse effects.
The best strategy is to still give that signal to people by teaching them the effects different drugs have, and teaching them to research something before they use it. Many, many thousands of people are addicted to painkillers, and new drugs which are still legal can cause serious harm too.
If you educate people, and regulate the drug market:
- (Problematic) use of drugs will decline
- The drug market will become legal, cause huge tax benefits and dealing a serious blow to criminality. Prisons will be half empty.
- Drugs will become cheap, so addicts don't have to steal or rob to support their habit, and don't wind up on the street
- Addict can be given professional help
In Holland a research group calculated that legalizing drugs would make all our huge budget cuts superfluous. For the Dutchies:

We should focus on regulating every drug. If done correctly, this will only have beneficial effects. And these social, economic, and medical effects are HUGE.
