No problem @ajn I’m sure that it has its benefits. All I wanted to do was alert people to the fact that cannabis can remain at a level that is above the legal limit to drive for several days after use. For example, someone using Cannabis on a Saturday night may assume that they would be safe to drive on Sunday. In reality, they are likely to still be over the limit on Monday and even Tuesday. Bizarrely, it stays in the system longer than some class A drugs.
