The Constitution doesn't grant rights. Rights are natural. The Constitution defines the nature of our government and the powers and responsibilities bestowed upon it, while the Bill of Rights, by many founders considered redundant, further restricts the power of the government to infringe on them. Just because something isn't specifically mentioned in the Bill of Rights doesn't mean that the government can legitimately legislate rights away.Hmm, wasn’t aware marijuana consumption was a constitutional right.
You have the natural right to do with your property as you wish so long as you don't violate the rights of others. You own nothing so much as your own self. Unless you are owned by others. That's called slavery and is prohibited by the 13th amendment to the Constitution. So, in a roundabout way, I'd say it is protected by the Constitution, even if, like many things, it is illegitimately infringed upon.
