@Brent cv,
It is dependant of the law. Supposedly when you are in you home no one can bother you. Do what you will, but up to a point. If you commit a murder in your home it matters not. If state law says no sodomy even in your home it is illegal. Same with drugs. If there were a right to privacy all would be legal in the eyes of the constitution. which superceeds state law. IMO
