Houston Drug Lawyer

Can the government prove possession?

The government must prove you:

  1. Knew of the drug’s existence; AND
  2. Exercised control over the drug.

If there is insufficient proof of either, our Houston drug criminal defense lawyers will push for complete dismissal.

Texas Drug Lawyer and Field Tests

Unreliable Drug Field Tests

If the officer used a field test during your drug arrest, to a qualified drug attorney the results are meaningless. Drug Field test are nothing more than unreliable, junk-science and inadmissible in court.

Drug Defense Attorney – Houston

Was the stop, search, and arrest lawful?

  • Did the officer have reasonable suspicion to stop you?
  • Did the officer have reasonable suspicion to detain you?
  • Did the officer have probable cause to search you?
  • Did the officer have probable cause to arrest you?
  • Did the officer obtain a lawful drug warrant?

If any of the officer’s actions were unlawful, then our Houston drug criminal defense lawyers should get the evidence suppressed.
