I wish my government was asking people to be careful buying weed.

Instead they prefer the "don't buy weed! you'll be an addict, lose everything, go to prison, detox, maybe you'll die die, or be a homeless hobo living under a bridge".
We're the opposite. I still prefer the negative perspective of our government or at least the majority of our population when it comes to marijuana's legalization, but the sad thing is I think this mindset will change sooner or later
just because one of the answers of the current reigning Miss Universe strongly influenced others' way of thinking. How silly to think that a simple answer from a pageant suddenly made our government officials to consider passing a bill/law favorable to marijuana

.
I'm not really against to its legalization because I know that it could :)contribute a lot for medicating patients. Maybe I'm just scared that time will come when the obedience of the policies and regulations regarding this just become an option that others will be out of control and can easily access it for "fun".
I'd recommend you not to blindly accept and follow the rules but question them. 100 years ago smoking weed was legal and nobody was put in jail for possession. Did that make everyone forget about their jobs and responsibilities and run high all day long? Of course not.
What you're experiencing is a baseless fear of the unknown that the government is inciting. They're telling you that if weed was legal your children would be able to get it and lower their IQ by getting high on regular basis. It's funny, because in many countries possessing small amounts of drugs for private use is not illegal, and in those countries there is no higher drug use than everywhere else. For instance in the Czech Republic possession of drugs is a misdemeanor, which means that if you're caught smoking in public you will get a fine, just like for pissing in a park. Despite that, people aren't smoking in public more than US citizens who can go to jail for the same thing.
