Medical Marijuana treatment and driving vehicles, including a bicycle. Good morning. I apologize in advance for the length of the post, but in order to include all my questions and concerns in it, I must write in one way and not another, counting on specific answers. I know that the topic has already been discussed, but it is quite a paradoxical issue, requiring corrections and specific legal solutions so that it does not fill patients with unnecessary anxiety. - I am a legal patient and take regular medical mj with thc, mainly in the evening and a micro dose in the morning. Riding e.g. by bike / car at 6 p.m., I am not high, but thc metabolites in the blood are found all the time. (and would be found even a few days after possible discontinuation of the drug) However, I am nervous about what if, for example, I am stopped by a roadman for a routine check-up and asks: "Do you use any psychoactive substances?" And then what>? Will the policeman understand that having something in his blood does not equal being under the influence? During routine check-ups: whether it is riding a bicycle or a car - to warn about the fact that you are a patient? On a lollipop test or in a urine/blood sample, a positive result will still come out. The only question is what approach the services have to this and whether they understand the issues of metabolizing THC in the body, or whether with a positive result they will not care that someone is a legal patient, and at the moment is not actually high. I believe that the law should be regulated here to some extent and some limit of nanograms of THC in the blood should be allowed. However, as you know today, there are no such records yet, what to do about it? To speak, not to speak? Count on the fact that the policeman will not come up with the initiative to take the test? Should you talk about everything honestly and openly? P.s. I would like to add that if it turned out that in connection with the metabolites of thc you can not currently drive at all - I will say this - with the lack of driving a car I would still reconcile, but cycling is necessary for me in everyday life. Now - as for cyclists, will the road be more understanding and understand that someone is a patient and it is as if he was taking SSRIs / Benzodiazepines, or can a policeman say that even cycling with thc metabolites is a crime and will not want to listen to the argument about medical legality and the need for treatment and, for example, will he refer the case to court? Thank you for reading the post and please reply. Yours sincerely!
