I did see that program....it did not impress me....or change my thoughts on the use of this substance.

Yes, you can buy alcohol and get off your face on it.....and some people do it.
It has a lot to answer for...but it has been available since the dawn of time.
It has been used and misused during that time.
In the US it was made illegal for a period of time.
It did not stop its' use.
Tobacco and alcohol are very large revenue generators for government coffers....so they will not bring in measures to curb the use.

Drinking alcohol and smoking tobacco does not(in the main) lead to the use of hard drugs.

Legalising these substances will not limit their use....the government would very likely tax it and this would still leave a market for illegal stuff.
