Why so anti cannabis?

CDU call Cannabis legalization a mistake, you can only have 9nanograms(whatever that none sense is) of it in your blood order to be able to drive. Walking around any busy area you get hit in the face with smoke from people cancer sticks, but y’all scream to the high heavens if you smell some weed even though half of Germany smells like manure the entire spring. What’s your problem with weed? I genuinely want to know if you are all still gripped by the war on drugs propaganda or if you all are actually knowledgeable on the plant and have an actual reasonable issue with it. Y’all are so loose with alcohol which is a literal nurotoxin and it’s proven to be much harder to drive under the influence of alcohol than it is under the influence of weed. So this whole anti weed attitude makes no logical sense. I need answers.
