Yes I do not think those drugs are safe for more reasons than the others in my head I just don't agree with drugs in general I don't think you can ever really know how they work in the body and what they may cause into the future. People used to think the medical treatment in the 1800's was safe and effective and accurate but only because they didn't have anything better to reference and some way down the future people will look back and say how terrible the medical treatment was for this time period. I don't think you can ever say a medical treatment is safe because anytime you alter the body there is a risk.
