Thank you for your feedback. It is really valuable to get the perspective of a frequent cannabis user. Cannabis tolerance is definitely a huge factor in determining whether or not someone is impaired. As a daily user, I am sure you are fine to drive after having used cannabis (although this is not legal advice :) ). However, people forget that there are significant tolerance effects for alcohol as well. There are people who can blow a 0.15% (well over the legal limit of 0.08%) and not exhibit any impairment symptoms. The key is finding a limit that allows police to identify actually impaired drivers while giving those with tolerance enough leeway to avoid being falsely charged. The scariest thing for frequent users is the blood legal limits being proposed in Canada and across the US, give that blood can have detectable levels of cannabis up to a week after abstinence. That is why one of our big focuses is finding a replacement for blood testing.

Thanks for your reply and engaging in this sort of discourse. I agree with all of your points, and also feel that technology in this area can help in conjunction with other indicators and tests to determine dangerously impaired driving. Any improvement over the existing testing methodology and legislation where some blood concentration possibly present from the week prior serves as enough for a felony conviction seems well warranted!

Given that is an impossible statement, it sounds like you are admitting this will be used to falsely prosecute more people than it will let off the hook. This is a smash and grab that will adversely effect society, not help it. You keep comparing it to alcohol, but you should be comparing it to adderall. Do you think society needs adderall testing curbside as well?
