The largest pot rally in the world is coming to Seattle this weekend, and the Washington State Patrol is gearing up, reports Smell the Truth.

Seattle Hempfest runs from August 16-18. Coincidentally, Washington State's "Drive Sober or Get Pulled Over" also starts on August 16 and will run until September 2. The focus of the driving under the influence campaign will be on stoned drivers.

As marijuana smokers celebrate newly legalized recreational marijuana use at Hempfest, authorities will be on the lookout for impaired drivers breaking the law by driving stoned.

As you may know, the legal limit to smoke weed and drive in Washington is five nanograms of THC. However, regardless of THC level, someone may still be arrested for a DUI if marijuana use impairs his or her driving ability. For example, even if you only have one puff of a joint and test for a THC level of one nanogram, you may still be arrested for a DUI if the marijuana negatively affects your driving ability.

Organizers of Seattle Hempfest anticipate over 100,000 revelers at the weekend-long event. With certain Washington police officers trained to be drug recognition experts, the odds are that some percentage of these revelers will be busted for a DUI.

If you face a drugged driving charge, it is important that you work with a defense attorney. Marijuana use and driving is a relatively new (and uncertain) area of law. As a result, an experienced DUI defense attorney can help you establish your defenses and negotiate with prosecutors.
