Look, whether you have superior knowledge of the qualities of MJ than I do, you have ZIP understanding of how narcotics destroy civilizations where the people abuse them.
I have no intention of letting you destroy America no matter how badly you feel the need to do that.
"The term narcotic, derived from the Greek word for stupor, originally referred to a variety of substances that induced sleep (such state is narcosis). In the U.S. legal context, narcotic refers to opium, opium derivatives, and their semisynthetic or totally synthetic substitutes. Cocaine and coca leaves, which are classified as "narcotics" in the U.S. Controlled Substances Act (CSA), are technically not narcotics.
Because the term is often used broadly, inaccurately and/or pejoratively outside medical contexts, most medical professionals prefer the more precise term opioid for all natural, semi-synthetic and synthetic substances that behave pharmacologically like morphine, the primary constituent of natural opium."

Your contention that Narcotics destroy civilization can be debated in another topic. The topic here is Marijuana and laws concerning it and it's derivitives. Marijuana is not a narcotic, nor is it addictive as you claim. Legalizing it will not end civilization as we know it or harm it in any way.
Your enemy is Poppy, another plant of infamy, where opium, heroin, and morphine come from. Don't get them confused.
Poppy has pretty pink, white, and red flowers. Cannabis has thick dense resinous flowers and is not all that pretty to look at unless you want to smoke it.
You have your preferences for one thing over another. So what?
