What is the penalty in Texas for possession of controlled substance meth over 4 grams as a second drug offense?

The answer is in the Texas Health and Safety Code, Section 481.115(d).

Possession of methamphetamine (a Penalty Group 1 substance) is a second degree felony. The Texas Penal Code, Section 12.33 says punishment for a second degree felony ranges from 2-20 years in prison and a fine of not more than $10,000.

However, under the Penal Code, Section 12.42, a second conviction is "enhanced" by a previous conviction. If the previous conviction was also a second degree felony, then the second conviction is eligible to be enhanced to a first degree felony which ranges in punishment from 5-99 years in prison and a fine of not more than $10,000.
