Seroquil for anxiety sounds like a serious overkill.
25 years ago I had severe generalized anxiety attacks and the only response I received from any MD was a script for meds that were addictive, over time. I refused them all beleiving then as I do now, severe anxiety is bad enough without risking addiction to control it. Like with everything, it passed. The attacks eventually stopped as suddenly as they started.
I have no doubt kids are mixing it with pot. Kids will mix dirt with pot if they think it will be a new buzz.
I often think we are turning into a culture of addicts.
