What the petition asks
We think cannabis blood tests can sometimes give inaccurate results, that could lead to people losing their jobs.
There are lots of different approaches to testing for cannabis use. We think cannabis blood tests are a flawed system giving inaccurate results. The results of these tests can vary depending on physical factors.
