In response to a question about having a tax stamp legalizing weed in one's possession, the answer is - NO.
The Texas Tax Code requires the State Comptroller to produce tax stamps for controlled substances. Stamps are $200 per gram for each controlled substance except weed. Pot is $3.50 per gram.
The Texas tax code states that "nothing in this chapter provides a defense or affirmative defense to, exception to, or immunity from prosecution under the penal laws of this state relating to controlled substances, counterfeit substances, simulated controlled substances, or marihuana."
Sound like double jeopardy? It is.

The courts ruling simply means you will only be charged for possession, sale or whatever, not for failing to pay taxes.
Texas marihuana tax stamps can usually be found on ebay for $10-20.
