No. A DUI is not limited to alcohol (which by the way is also "legal"). The issue in a DUI is whether or not you were operating a motor vehicle while under the influence of alcohol or drugs. The legality of the alcohol or drugs is irrelevant. In your instance, you are not going to be offered a breath test because, the breath test only measures alcohol. By refusing a blood draw, you may well have lost your license for one year even if you are found not guilty of the DUI. This is what is called the implied consent law it is a privilege to drive not a right. As such, when you receive your drivers license, you give the "implied consent" that if an officer makes a valid stop and has probable cause to believe that you are under the influence and you refuse the test, then the Department of License can suspend your license. My advice: hire an attorney.
