Is Seroquel a controlled substance?

Although Seroquel is often abused and sold as a street drug it is not a government controlled substance. It is only available by perscription but is not government controlled the way that other similar drugs such as valium or xanax are. That being said it is felt by many people that Seroquel is a strong anti-psychotic drug and should be better controlled to prevent such abuse. Street use and abuse of this or any drug is dangerous and can leave lasting effects.
