So why do you believe them?
Do you believe marijuana is more harmful than alcohol? If not, do you favor criminalization of alcohol?
No by saying its not a universal truth, it was an admission that just because a government chooses to spend money on raising awareness over a certain issue, doesn't mean to say that the the view of the government is necessarily the correct one.
That said it is irrelevant because regardless, I happen to believe the governments education campaign relating to drugs, and so whether or not what the government says is always right or not is unimportant.
I believe that marijuana is a potentially harmful drug whose use shouldn't be endoresed by the government through its legalisation.
Alcohol is one of the most destructive drugs in terms of damage to individuals and harm to society, but this is mainly because it is legal and so easy to obtain and over expose oneself to.
Likewise, I think that if currently illicet drugs such as marijuana were made legal, the number of people using them would increase dramatically and as such it would cause more harm to society. The fact that it is illegal is a major deterant to its use and severly increases the risks associated with obtaining it.
I don't think the government on a practical level could ban alcohol even if they wanted to as it is engrained as an almost central aspect of Western and Australian culture.
