What meth level is legally prohibited? 7 Answers as of March 12, 2012

No specific legal level, other than it is measurable in the blood. Breathing fumes will get you there.

All meth is illegal. As to a DUI and the amount in your system, my undersatnding is there is no correlation as to any specific amount.

Unless you have a valid prescription, no amount is legal.

There is no magic number like in a DUI case. It's whether or not they can prove that you were under the influence. Individuals react differently to different levels, so the number matter, but there's no set base level. If your symptoms were inconclusive and the levels were low, it could lead to a not guilty and/or dismissal. You'll have to discuss the entire case with your attorney though.

All meth levels are prohibited.

A very interesting question that is the subject of much debate in the legal and scientific community right now. The present answer (unless there is alcohol involved as well) is that there is no established level of intoxication for meth (or any other drug). Scientifically, there are some studies that suggest that some people actually drive better, are more alert, with certain amounts of meth in the system. The legislatures in many states are taking a serious look into this right now, and for many drugs, are trying to pass statutes prohibiting the use of any amount in the system while driving despite this scientific uncertainty. So, the issue for you will boil down to whether you were "under the influence" (a defined element) while driving. This could be shown by the level of drugs in your system coupled with objective symptoms, the field sobriety tests, and observed driving. This is a hot-bed area of criminal defense right now. Bear in mind, though, that being under the influence of a controlled substance, and possession of a controlled substance are separate charges themselves, and can be felonies depending on the substances. Get a good criminal defense attorney to help you with this. It is not as easy as it might sound and even many lawyers are unaware of the technicalities of DUI-drugs.

This is a difficult issue to prove, that is why you should contact a lawyer to help you. A lot of times these cases can be reduced or even dismissed via statute (if you complete a drug class).
