I think you did a great job covering this extensive, illegal(in most places), and not giving medical advice. That's the clincher when you talk to people like us about a treatment, though benign, it's unorthodox and illegal. So we can only go on what we know thus far. Whether DEA, Congress, or States want to recognize it, yes marijuana is more effective in pain relief than opiates, because it's stress relief, muscle relaxation, neuralgia pain relief, migraine relief and pain relief. Yes there is some down time with a euphoric feeling. Lie down, read a positive book, pray, meditate, take some you time. Opiates modify our moods, also. We shouldn't operate machinery or drive under the influence of opiates. This subject is a thesis. My goodness all because someone might take a puff too many enjoy themselves and giggle! Someone call the Joy Gestapo, someone might crack a smile!
