Show me the right you have to cause damage to others in public and liability to your potential employer.

All of which can be dealt with via laws regarding said damage and liability. But those laws are state and local laws. My specific question is, where is the War on Drugs enumerated in the Constitution as a power of the Federal government?

I've dealt with enough pot smoking losers of late (all of which get aggressive and violent with all the pot) and it is a cancer on Americans and our children if it appears acceptable to them.
I can only see it for cancer or other dying people. The rest IMO are just junkies trying to get mainstream

“My specific question is, where is the War on Drugs enumerated in the Constitution as a power of the Federal government?”

The Constitution specifically directs the federal government to provide for the common defense.

Drug cartels are not in the business of empowering Americans and keeping them safe. Furthermore, they are highly organized and well funded. Via the common-defense language throughout the Constitution, the federal government provides for our common defense against the cartels.
