IMO you are caught in the trap of ethno-centrism. i.e. you refuse /or seem incapable of understanding the term used (pursuit of happiness) in the profane and modern sense and ignore its original meaning—oops— just knocked the old lid off that can of worms again—Sorry.

I don't think it adds to the conversation to assume that the framers equated “pursuit of happiness” with being high on methamphetamines or heroin. In the TV series “Adams” there is a great piece of dialog on what the intent was regarding this little phrase.

O thou seer of man’s understanding and intent, at least do us the favor of expounding on original intent as it applies to the words, “pursuit of happiness.” Obviously it means more than the shallow pursuit of self-gratification. On the other hand, I would not go so far as to suggest it completely rules out the right for an individual to use substances that lighten the burdens of every day life, or increase industry.

Here is a decent explication on the phrase "pursuit of happiness." There tends to be a wide interpretation otherwise.
