Very good post Caps!! I couldn't have said it better myself.
It all goes back to the perceived threat of the drug. Heck there are some perscrition drugs that have HORIBLE side effects and this that and the other, but they are not stigmatized as being bad because they are prescrition. We have a mentality in this country to see scripts as ok, but they are the most widely abused drugs out there. They are just "legal" because of the script and they are prescribed.
Cannabis has a bad rap because of propoganda after prohabition ended and something about the lazy mexican. The DEA needed something to go after so they stigmatized pot since alcohol was legal again.
I agree that there cannot be a one blanket answer to the issue because it is WAY more complex than that.
