A driving under the influence conviction can follow you well beyond the courtroom. Depending on the circumstances, you could face incarceration or house arrest, a driver's license suspension, ignition interlock requirements, and additional consequences if you drive while suspended.

A decades-old criminal conviction may still be affecting your right to possess a firearm. Federal law provides a process under Title 18 of the United States Code, Section 925(c), through which certain individuals may seek restoration of their federal firearm rights.

Eligibility is highly dependent on the facts of the conviction, the person’s history since that conviction, and any separate state restrictions that may still apply. If an old conviction continues to affect your firearm rights, Patrick Nightingale can review your circumstances and help you understand whether a path forward may exist. Schedule a consultation at (412) 454-5582 or patricknightingale.com.

A police report may describe signs of impairment, but dash camera and body camera footage can provide a much clearer picture of what actually happened. The recording may show how the vehicle was being driven, how field sobriety tests were administered, and whether the officer's description is supported by the evidence.

A product can be sold openly in a smoke shop, labeled as h**p, and still raise serious legal questions. THCA flower and other intoxicating h**p products have exposed a gap between what consumers see on the shelf and how cannabis may be classified under federal and Pennsylvania law.

08/27/2026

The 2018 Farm Bill did more than legalize certain forms of h**p. Its definition of h**p helped create a rapidly expanding market for intoxicating products containing compounds such as delta-8 tetrahydrocannabinol, delta-10 tetrahydrocannabinol, and tetrahydrocannabinolic acid.

08/26/2026

Cannabis products marketed as Farm Bill compliant continue to raise important questions in Pennsylvania criminal cases. A label may claim a product is legal, but the real issue is whether the testing and documentation actually connect that specific product to cannabis that satisfied the applicable requirements before harvest.

08/21/2026

Federal h**p law is changing, and the consequences could extend beyond products designed to produce an intoxicating effect. Beginning November 12, 2026, the federal definition is scheduled to consider total tetrahydrocannabinol, including tetrahydrocannabinolic acid, while certain finished h**p-derived cannabinoid products will face an extremely low per-container limit.

08/21/2026

THCA cases raise a basic question that can become very complicated in court: can the prosecution actually prove that the cannabis seized was not Farm Bill compliant when it mattered? A receipt or certificate of analysis may show that a product was represented as compliant, yet the connection between that document and the specific plant material seized can become a major evidentiary issue.

These cases can turn on testing, documentation, chain of custody, and whether the government can establish that the substance falls outside the legal definition of h**p. If you are facing a cannabis or drug-related investigation, you can schedule a consultation with PKN Law at (412) 454-5582 or patricknightingale.com.

A driving under the influence case often starts long before field sobriety testing or a chemical test. One of the first questions I ask is whether law enforcement had a lawful reason to stop the vehicle in the first place. The details surrounding that traffic stop can matter throughout the case. If you are facing a driving under the influence charge in Pennsylvania, PKN Law can review what happened from the beginning and determine whether the stop should be challenged.

A major federal ma*****na change could have a direct impact on Pennsylvania medical ma*****na patients. The change may affect how prosecutors prove driving under the influence cases involving properly authorized medical ma*****na, while firearm ownership raises a separate and much more complicated legal question.
