Congress has the authority to regulate trade and commerce.
Drugs are trade, a commodity that can be regulated and taxed. Section 8 is more than just those words “general welfare.”
If Congress taxes some drugs at 100%, it is their exclusive authority to do so.
The proliferation of recreational drugs is chemical warfare against the young people of this country and Congress is also authorized to provide for the “common Defense.”
To put it plainly, you don't have the slightest idea of what you are talking about...
Instead let me introduce Thomas Jefferson, had you been familiar with this man at all you would have understood my comments.
Jefferson expains precisely what I said about the limits of Section 8, but of course he says it far better;
"I consider the foundation of the Constitution as laid on this ground that "all powers not delegated to the U.S. by the Constitution, not prohibited by it to the states, are reserved to the states or to the people" [XIIth. Amendmt.]. To take a single step beyond the boundaries thus specially drawn around the powers of Congress, is to take possession of a boundless feild of power, no longer susceptible of any definition. (just what I said)...snip...
1. "To lay taxes to provide for the general welfare of the U.S." that is to say "to lay taxes for the purpose of providing for the general welfare." For the laying of taxes is the power and the general welfare the purpose for which the power is to be exercised. They are not to lay taxes ad libitum for any purpose they please; but only to pay the debts or provide for the welfare of the Union. In like manner they are not to do anything they please to provide for the general welfare, but only to lay taxes for that purpose. To consider the latter phrase, not as describing the purpose of the first, but as giving a distinct and independent power to do any act they please, which might be for the good of the Union, would render all the preceding and subsequent enumerations of power completely useless. It would reduce the whole instrument to a single phrase, that of instituting a Congress with power to do whatever would be for the good of the U.S. and as they would be the sole judges of the good or evil, it would be also a power to do whatever evil they pleased. It is an established rule of construction, where a phrase will bear either of two meanings, to give it that which will allow some meaning to the other parts of the instrument, and not that which would render all the others useless. Certainly no such universal power was meant to be given them. It was intended to lace them up straitly within the enumerated powers, and those without which, as means, these powers could not be be carried into effect. It is known that the very power now proposed as a means, was rejected as an end, by the Convention which formed the constitution." -- Thomas Jefferson, The Founders' Constitution Volume 3, Article 1, Section 8, Clause 18, Document 10
Before you step in and debate further I suggest a review of the writings of the founders.
The very problem we have with the monstrous, outrageous government to day is that men are undeducated and no longer behave like men.
