DUI & Impaired Driving

Edmonton Marijuana DUI Lawyers

If you have been charged with a marijuana DUI offense in Alberta, you will need an experienced and aggressive defence lawyer who truly has your best interests in mind. Call Haryett & Company in Edmonton and let us use our experience, knowledge and resources to fight for you. The penalties of a marijuana DUI conviction, even for a first offense, can include severe fines, court fees, increased car insurance premiums and loss of driving privileges, not to mention the potential damage to your reputation.

Signs of Driving Under the Influence of Marijuana

There are a number of signs that indicate to law enforcement that a driver could be under the influence or impaired by marijuana, including:

  • Slurred speech
  • Bloodshot eyes
  • Smell of marijuana in car
  • Driving excessively slowly
  • Erratic driving behaviour
  • Impaired cognitive function
  • Impaired motor skills

If you are also found in possession of marijuana, drug paraphernalia or both at the time you are stopped, you will also face additional charges related to the possession of drugs and drug paraphernalia. The consequences of these additional charges could be substantially more severe than the DUI charges and involve fines, court fees, community service and jail time.

Marijuana DUI Defence

First, it must be determined that the police had reason to pull you over. If or when it is established that the police had sufficient reason to pull you over the focus of the defence may shift to how the marijuana was detected in your system. There can be flaws in a marijuana blood or urine test that can help your case in court. Flaws may be test accuracy, was the marijuana medically prescribed and how long had it been since you ingested it prior to driving. We will use our extensive experience of Alberta DUI and marijuana laws to devise a strategic defence. Our ultimate goal is to have your charges dropped, dismissed, or mitigated in any way we can.
