Hello, Mr Kennedy wrote on marijuana impaired driving and a person participating in simulated driving claiming it was rigged. We do marijuana impaired driving. And each project we have collected data ... when the blood results come in, there were volunteers claiming to be high but had not used marijuana and just wanted to bias the results showing no impairment. The vast majority of volunteers from the marijuana industry are truly interested in a safe marijuana experience and tend to be reliable...but there are those who do not have the public interest or safety in mind and just have motives, often political.
