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.
