Pot heads think they have a constitutional right to smoke marijuana. Just ask them. They'll tell ya, its their right to get stoned on marijuana. LOL
Okay, you have adequately represented the "pot heads" and "dope smokers" I think it was. But you have NOT adequately represented those of us who wouldn't dream of smoking a joint (or any other recreational drug, including alcohol), but who still know that the Constitution does not in any way grant rights to smoke marijuana or for a citizen to do anything else. The Constitution, in the Bill of Rights, makes explicit those natural rights we already have that the government cannot abridge and lists the rights that the GOVERNMENT may employ to maintain a civil society.
That may be too subtle, but is an important distinction that many of us make and wish weren't being eroded. Just pass the Amendment to ban marijuana and I'll go along with you. Until then, the Constitution is silent---therefore, it's none of my or your business at the federal level.
You probably won't tackle that and certainly can't tackle it with any intellectual rigor.
