Personally I'm all for legalising most drugs because it would put drug dealers out of a job and tbh if people want to portugal themselves up I feel that is their choice. Also a few currently illegal substances are rather nice.
That's not going to happen.
Cigarettes and alcohol are also dangerous, but tolerated. Do you ask yourself why?
Now here's how the politicians see it:
- Marihuana (not even talking about other drugs here) can ruin
* younger people who are just starting their school/career. They will become a burden for society = less profit on taxes
- Long term consequences of cigarettes and alcohol will often show on older people. You know what's wrong about old people? They are retired (in most cases). Getting rid of them = profit! (just speeding up natural process in order to get more money)
Don't think that politicians care about something else than money.
* ruin - not really defined, but marijuana is usually considered as a first step in the bigger world of more dangerous drugs. And as we all know that usually happens in the teenage years under peer pressure.
