Plus, unless it’s in your sources, which I didn’t check, you should be aware that God also put receptors in our brains for opiates and cannabis... which suggests to me that He meant for us to be able to use these substances as medically indicated. The intoxicating part of the drug passes through the brain/blood barrier and hits its receptor in the brain. Gee, do you suppose that today’s nanny state would ARREST GOD if they could, for enabling us to become intoxicated (feel good) by some of the drugs He ALSO put on earth? I can just picture the drug warriors trying to bust down Heaven’s main gate to get to God and arrest Him.
We also found that God put benzodiazepine receptors - think of Valium - there and in peripheral receptors too. I would tax natural plants and substances, making it legal. Synthetic chemicals and drugs would remain under the FDA and DEA. If someone wants to smoke opium, it's better than using intravenous needles spreading HIV/AIDS, various types of bloodborne hepatitis and God knows what else. If they want to chew coca leaves or khat, so be it.
There are drug treatment programs for those who can't control it. As it is, the war on drugs is funding Al Qaeda, the Taliban and organized crime besides threatening our civil liberties.
