You are right, and the key in the equation is the right to "regulate", which even when done vigorously results in the current pain killer issues.
Do not misunderstand. I said that if pharmaceuticals can be derived from cannibis, they should be regulated as are all pharmaceuticals. They should not be available except as prescribed by a physician to treat a legitimate malady. There is no tax on prescription medicines.
I might argue however that many products offer medicinal benefit without being regulated as a pharmaceutical. Vitamin supplements etc., but, I'm not saying cannibus is in that class.
Yes, you might argue that, but you would be incorrect. Over the counter products cannot carry a statement or advertise that they can treat, cure, or improve any medical condition. If you don't believe this, read the fine print, or listen carefully to the advertising sales pitch and you'll discover the disclaimers.
Liquor is one of the major sources of tax revenue for the states.
Maybe so. However, the cost to the public far outweighs the tax revenues. Treatment of alcohol related diseases is one of the reasons that Medicare is a losing proposition. It accounts for a substantial share of welfare and unemployment benefits, too.
Cannibus offers the same opportunity if properly regulated, manufactured and taxes.
As if things are not bad enough already, you propose making them worse.
Afterall, these states are lining up to put slot machines and casinos everywhere, to cut their budget deficits... why not a sin tax on pot?
For all of the reasons stated above.
