Final answer:
While the provided information discusses the historical Eighteenth Amendment, the definition of "intoxication" in Texas law is actually found in the Texas Penal Code, Section 49.01.
Step-by-step explanation:
The code that clearly defines "intoxication" as it applies to the state of Texas is not provided within the provided information.
However, the discussion of the transportation or importation of intoxicating liquors relates to historical context, particularly regarding the Eighteenth Amendment.
This Constitutional Amendment, ratified in 1919, prohibited the manufacture, transport, and sale of intoxicating liquors and was part of the Prohibition era.
While this federal amendment applied to all states, including Texas, it was later repealed by the Twenty-First Amendment in 1933.
Therefore, to find the current legal definition of intoxication in Texas, one would need to refer to the Texas Penal Code, specifically to Section 49.01, which defines intoxication with regard to alcohol concentration levels or loss of normal mental or physical faculties.
