Just when did the government get this right? Certainly not in the constitution. Congress may not pass any law that violates the limits of Federal authority spelled out in Article 1, section 8 or added by amendment.
You will note that when they wanted to ban alcohol, they still remembered this and passed an amendment to give them the authority. Absent the 18th amendment, they had no such authority. What is the number of the amendment that was passed to give them similar power over drugs? I can't seem to find it.
If you are truly a conservative, then you should be upholding the constitution and demanding an end to the unconstitutional and insane drug war. Otherwise people might think that you are showing some fascist colors.
The The Controlled Substances Act of 1970 and the Supreme Court decision in Touby v. United States, 1991, are the legislative and legal foundation for the federal governments efforts against the abuse of drugs and other substances.
This is a conservative website and I am a conservative. If you don't agree with America's national drug control policy, work to get it changed. Just watch the inflammatory rhetoric.
